Puntos fuertes de Avast Antivirus 2019

Avast Antivirus 2019 tiene funcionalidades interesantes que se ofrecen ya desde su plan más básico, lo que hace de él un buen antivirus para aquellos que no quieren gastar mucho en el mismo.

Ventajas

      • Bloquea malware de todo tipo: virus, troyanos, etc.
      • Gestor de contraseñas
      • Analiza vulnerabilidades wi-fi
      • Se pueden abrir archivos sospechosos de forma segura
      • Cortafuegos
      • Protección de correo electrónico: spam y phishing
      • Escudo ransomware
      • Modo no molestar para cuando juegas o ves películas

Avast Internet Security

Avast Internet Security es un plan que ofrece una protección de nivel alto a un precio razonable. Hasta 2016, Avast no conseguía ofrecer una protección al nivel de los mejores, pero a partir de 2017 ha cambiado y según los tests de av comparatives, su peor resultado en los últimos años ha sido una detección del 98,6 %. Si a eso le añadimos una potente apuesta por cuidar el rendimiento del ordenador, la conclusión es que Avast es uno de esos antivirus que aunque nos proteja, no va a hacer que nuestro procesador se vuelva lento y pesado.

La licencia se adquiere para un PC, pero el aumento de precio para tres PCs es menos de la mitad del precio, por lo que no es mala opción.

En cuanto a protecciones específicas, ya el plan de pago más básico tiene todos los puntos fuertes que hemos mencionado arriba. Además de eso, comprueba los DNS de las webs que visitas para que no entres en webs fraudulentas que se hacen pasar por legítimas.
Puedes probarlo sin compromiso durante 30 días, y si no te gusta te devuelven el dinero, así que no tengas miedo a hacerlo ya que no hay nada como probar un software de verdad, para saber si es el adecuado para ti.

Avast Premier

Como siempre el plan Premier de Avast Antivirus cuenta con todas y cada una de las protecciones del plan anterior. Además, añade algunas cositas interesantes que pueden merecer la pena en función del uso que hagas de tu ordenador.

La primera es el bloqueo de webcam, de modo que solo las apps a las que tú des permiso tendrán acceso a ella. Así, nadie podrá grabarte y enviarte el típico email de intento de extorsión. Estos correos electrónicos casi siempre son falsos y es raro que el timador haya tenido acceso real a la webcam, pero desde luego no es imposible y pasa de vez en cuando.

Muy interesante también es la posibilidad de destruir archivos de forma permanente para que no se puedan recuperar, ya que normalmente cuando envías archivos a la papelera de reciclaje, estos sí que se pueden recuperar.
Finalmente, ofrece un actualizador de software que te permitirá tener todos tus programas a la última, lo que es una medida de seguridad importante, ya que los desarrolladores suelen mejorar la seguridad de sus programas y apps según se van dando cuenta de las debilidades.

Avast Ultimate

El plan premium de Avast Antivirus 2019 se llama Ultimate y ofrece extras importantes a los planes anteriores. La verdad es que nos parece que Avast es de los antivirus que mejor escalan sus planes y que mejoran el producto de acuerdo al precio de una forma muy lógica.

El plan Ultimate te ofrece un gestor de contraseñas mejorado que notifica cuando ha habido una filtración de contraseñas y te permite iniciar sesión con un solo clic.

También añade la opción CleanUp para eliminar archivos que ya no se usan y mejorar el rendimiento del ordenador.
Finalmente, la mejor característica es que te da la posibilidad de navegar mediante una VPN de forma que nadie sepa que eres tú quien visita las páginas que visitas. La navegación VPN de Avast se basa en OpenVPN y OpenSSL y lleva un cifrado Cifrado AES de 256 bits. En nuestra opinión la navegación VPN es uno de los servicios más interesantes de los softwares de antivirus.

Protección móvil

La protección móvil de Avast te permite analizar el dispositivo, bloquear virus y otro malware, detectar apps maliciosas, detectar links nocivos en los SMS y comprobar la seguridad de la red wi-fi antes de conectarte. También podrás bloquear el spam y, atención otra función interesante, las llamadas no deseadas. Asimismo te permite localizar tu dispositivo y bloquearlo o borrar los datos confidenciales de forma remota.

Aparte de esto, con el plan Pro puedes poner una contraseña a las fotos y otras apps que quieras proteger de forma extra, hacer fotos o grabaciones secretas si te roban el dispositivo y configurarlo para que el dispositivo se registre como perdido en el momento en que cambie la SIM.

Y con el plan Ultimate podrás navegar mediante VPN igual que podrías hacerlo desde el ordenador.

Conclusión

Avast Antivirus 2019 es un antivirus más que interesante y por ello lo incluimos en nuestro top 10 de mejores antivirus. ¿Por qué no está más arriba en la lista? Sencillo, debido a que la funcionalidad de navegación VPN solo está disponible en el plan Ultimate. Pero si lo que quieres saber es si Avast te va a proteger bien de todas las amenazas online, la respuesta es sí. Su software de detección y limpieza está entre los mejores y el rendimiento del ordenador no se ve afectado, ofreciendo una experiencia de uso fantástica.

Desde luego es un Antivirus que merece la pena probar, ya que hay bastantes posibilidades de que si se hace, se decida continuar con él. Como te ofrecen 30 días de prueba sin compromiso, tampoco perderás nada por hacerlo.

¡Protege tus dispositivos desde ya!

Conoce los peligros de usar las extensiones de tu antivirus en el navegador

A finales del pasado año conocimos como la extensión AVG Web TuneUP del antivirus gratuito AVG, causaba problemas a los usuarios del navegador Google Chrome, al exponer la totalidad del historial de navegación a ciertas páginas que se visitaban debido a una vulnerabilidad descubierta en las APIs de JavaScript. Esto creaba la paradoja de que una herramienta de seguridad expusiera la información personal del propio usuario en Internet, algo que tratamos de proteger a diario.

Lejos de encontrarnos ante un caso aislado, cada vez se suceden las incompatibilidades causadas por las extensiones de las suites de seguridad y otro buen ejemplo de ello lo encontramos en su día con la extensión de Avast! Online Security, un add-on para el navegador que trataba de protegernos en nuestra navegación diaria. El problema vino cuando los usuarios que la instalaron fueron testigos de la aparición de la barra de herramientas de SafePrice, un comparador de precios online que se derivaba de la instalación de la extensión de Avast.

Lo cierto es que muchas de las funciones de esta clase de barras de herramientas o extensiones del navegador son duplicidades de las ventajas que ya ofrecen navegadores como Google Chrome o Mozilla Firefox, e incluso el buscador Google cuentan con una enorme base de datos con la cual cotejan las páginas web mostradas en los resultados para filtrar las páginas que pueden incluir malware o esconden trampas de phising.

Protégete con tu antivirus del malware que se descargue a tu PC

Además hay que recordar que la mayoría de páginas web que ocultan algún tipo de virus basarán el ataque sobre el usuario en la descarga de un archivo malicioso a nuestro ordenador, algo que el propio antivirus supuestamente se encargará de bloquear, tengamos o no activas las funciones de navegación segura que pueden ofrecer a través de extensiones adicionales.

  • Foro de seguridad informática

Lo primordial al final y al cabo es encontrar un antivirus, ya sea de pago o al menos gratuito, con el que podamos estar protegidos durante todo el tiempo y que tengamos actualizado a la última versión para tener al día la base de datos de virus.

What does it take to promote a simple antivirus to security suite status? Firewall and spam filtering are among the popular additions, and Avast Internet Security has both of those. It also adds ransomware protection to prevent modification of important files, and a sandbox feature that experts can use to examine suspect files. However, some users may be put off by the many apparent bonus features that turn out to require an extra fee.

An Avast suite subscription costs $59.99 per year, or (more practically) $79.99 for three licenses. That’s a popular price point; Bitdefender, ESET, Kaspersky, and Trend Micro all go for the same. You pay $89.99 per year for McAfee Internet Security, but that subscription lets you install protection on every device in your household.

Astute readers may notice the absence of Avast Pro Antivirus in this discussion. That product is on the outs, and not promoted for new installations—though existing users can renew. When you click a non-free component in the free antivirus, it prompts you to upgrade to this suite.

Appearance-wise, this suite looks almost identical to the free antivirus product. The main Status page features a big notification saying, «You’re protected,» with a button to launch a Smart Scan. A simple menu down the left side lets you view features related to Protection, Privacy, and Performance. The main difference is that suite-specific features aren’t locked away.

Features Shared With Avast Free Antivirus

Avast Free Antivirus comes with Avast’s full arsenal of malware protection, plus a useful collection of bonus features. It’s one of our Editors’ Choice products for free antivirus, and naturally this suite includes all the same protective features. You can read my review of the free antivirus for a deep dive on the features shared by both products. I’ll summarize my discoveries here.

Lab Test Results Chart
Malware Protection Results Chart
Phishing Protection Results Chart

All four of the independent testing labs that I follow track Avast closely. It earned 17.5 of 18 possible points in tests by AV-Test Institute, and it achieved an Advanced+ rating (the highest possible rating) in all four tests by AV-Comparatives. SE Labs certified it at the AA level, the second-best of five certification levels. And it passed both rigorous tests imposed by MRG-Effitas.

I use an algorithm to map all scores onto a 10-point scale and generate an aggregate result. Like Avira, Avast came in at 9.6 points, with results from all four labs. Kaspersky retains the overall lab-test crown, with a perfect 10 points. Bitdefender came in next, with 9.9 points, though its omission from the latest MRG-Effitas tests means its score derived from just three of the four labs.

Avast earned 8.9 points in my own hands-on malware protection test. That’s good, but several products did even better. Tested against the same collection of samples, Cylance, F-Secure, Norton, and McAfee all managed 9.3 points. Webroot SecureAnywhere Internet Security Plus earned a perfect 10 points, but that achievement used my previous sample set, so it’s not directly comparable.

To get insight into how well each product handles the very latest malware problems, I start with a feed of malware-hosting URLs discovered by MRG-Effitas within the last few days. Avast directed the browser away from 62 percent of the 100-odd URLs and wiped out the malware download for another 29 percent. Its total of 91 percent protection is good. However, Symantec Norton Security Premium and McAfee both managed 99 percent protection in this test.

Phishing websites don’t attempt to plant malware on your system or subvert vulnerable applications. Instead, they try to trick you, the user, into blithely giving away your precious login credentials. To this end, they imitate sensitive websites such as banking sites, shopping sites, even gaming and dating sites. It just takes one unsuspecting victim to make the whole charade worthwhile.

Avast’s web-based protection really went to town on my freshly gathered phishing sites. It correctly identified 98 percent of them as frauds, steering the browser to safety. AVG scored exactly the same (no surprise, given that it uses the same engine); ZoneAlarm and Trend Micro Internet Security(39.95 3 PCs / 1 Year at Trend Micro Small Business) also managed 98 percent. However, even that estimable score doesn’t receive the antiphishing prize. Bitdefender edged out Avast with 99 percent, while Kaspersky and McAfee managed 100 percent protection.

Other Shared Features

Clicking the Smart Scan button on the main window launches a multifaceted system scan. It checks browser add-ons, scans for active malware, identifies performance issues, seeks out for network security problems, flags software that lacks security patches, and warns about weak passwords. That scan took about 10 minutes in testing, while a full system scan for malware needed more than two hours to complete, which is a good bit longer than average.

The Wi-Fi Inspector crawls your network (Wi-Fi or wired) and lists all found devices. In a modern household, full of Internet of Things devices, the list can be quite long. It displays its findings visually, with the router at the center surrounded by concentric circles. Devices that have connected most recently show up in the innermost circles. And it flags any possible network security problems. This feature works in much the same way as the free and separately available Avira Home Guard and Bitdefender Home Scanner utilities.

Implemented as a browser extension for Chrome and Firefox, Avast’s password manager component handles all the basics. It captures credentials as you log in to secure sites, and offers to replay them when you revisit those sites. It handles multiple sets of credentials for the same site, and two-page login forms don’t give it trouble. Avast doesn’t offer a complete form-fill system, but it will fill credit card data in web forms. You won’t find advanced features like secure password sharing or two-factor authentication, but it takes care of the essential tasks of a password manager.

The Online Security feature, also implemented as a browser extension for Chrome and Firefox, adds another layer of defense against malicious and fraudulent websites. It marks dangerous links in search results pages. You can use it to actively block ad trackers and other trackers from gathering information about your online activities. Its SiteCorrect feature kicks in when you misspell a popular domain name, keeping you safe from typosquatting sites.

You’ve heard again and again how important it is to install all security updates. But keeping everything up to date can be so frustrating! When you launch an app, you want to use it, not spend time on a suggested update. Avast’s Software Updater component works in the background to locate apps with missing security patches; you can also manually run a scan whenever you like. Just click the button to automatically install all found updates. Easy!

Of course, it could be even easier; if you turn on Automatic Updates it all happens totally without user interaction. But there’s a catch; turning on that feature requires an upgrade to the Avast Premier mega-suite. This component is just fine without full automation.

Still Some Extra-Cost Options

Even though you’ve paid for a security suite, quite a few of the components still require an additional fee for full functionality. In a couple cases, you really don’t need the Pro edition. As noted, you don’t get fully automated software updates without upgrading to Software Updater Pro, but the free edition does almost everything. A Pro subscription for the password manager component adds only minor goodies, among them 24/7 tech support, fingerprint login on mobile, and breach notification.

Other components just don’t work without an upgrade, however, and some of them reserve this news until you’ve already invested time in them. For example, when you launch Cleanup Premium, it scans your system for useless and erroneous items that it can delete to free up resources. It’s only when you click the button to resolve problems that you learn about this component’s separate license fees. As with Cleanup Premium, the upsell for Driver Updater doesn’t appear until after you’ve gone through the scanning process, which is frustrating.

On the Privacy page you’ll find an icon for Avast’s SecureLine VPN utility. Flipping the VPN’s switch to On reveals that you don’t yet have full access to this feature. You can enable a 60-day free trial, which is nice. But eventually you must pony up a substantial extra subscription to use the VPN.

As noted earlier, the Online Security component includes the option to actively block ad trackers and other trackers that try to profile your online activities. AntiTrack Premium goes beyond the basics, but I’m not yet sure just how. Clicking Learn More simply brings up a page showing that you must upgrade to Avast Premier in order to use the feature.

A couple more features are also locked behind the same upgrade requirement. Going for the Avast Premier mega-suite unlocks the Data Shredder, which deletes files securely, to foil even forensic recovery. It also lets you use the Webcam Shield spyware protection tool.

Robust Firewall

So, just what do you get by upgrading from the free antivirus to the full security suite? For starters, the suite adds a robust two-way firewall component. That’s the heart of most suites—antivirus plus a personal firewall.

For firewall testing, I use a physical PC that’s configured to connect through the router’s DMZ port, which effectively connects it directly to the Internet. When I challenged the test system with port scans and other web-based tests, it correctly put all the ports in stealth mode, so external attackers can’t even see them. This is no great feat, given that Windows Firewall alone can do it. It’s only relevant if a product fails to do what the built-in firewall can.

The other major task for a personal firewall is making sure programs don’t abuse their access to your network and internet connections. The firewall components in Norton and Kaspersky configure permissions for known programs and keep an eye on unknowns, making their own security decisions. I approve; relying on the user to make important security decisions is a bad idea. Other firewalls handle unknowns differently. For example, adaware antivirus total defaults to just allowing all traffic. Panda allows outbound connections but blocks unsolicited inbound connections.

For program control, Avast defaults to a mode called Auto-decide, meaning that (like Norton) it makes its own decision about each new program. For testing, I tried switching to Ask mode. Doing so didn’t result in a spate of popups about internal Windows components, because Avast had already created rules for those components in Auto-decide mode.

When I tried to get online using a browser that I coded myself, Avast first ran a quick analysis on the never-before-seen program. After vetting the program as safe, it asked whether to allow or deny its access to the internet. Avast, unlike many competitors, defines five levels of network access, but only a true firewall expert should consider switching away from the default level the firewall suggests.

If you click deny when you meant allow, or vice versa, you can open the full list of applications and correct your mistake. This list also shows all the application rules that Avast’s Auto-decide mode created on its own. If you dig deeper into the firewall’s settings, you can find extremely complex rules that even I wouldn’t consider editing. Leave these alone!

Protecting against network-based attempts to exploit vulnerabilities in the operating system or important apps is not precisely a firewall function, but it’s often included. Exploit defense isn’t something Avast attempts, as I verified in past reviews.

As part of my firewall evaluation, I check to make sure a malware coder couldn’t simply turn off protection. I couldn’t find any chinks in Avast’s armor. It protected its Registry settings against modification, and when I tried to terminate its processes, I got the message «Access Denied.» The same happened when I tried to disable its essential Windows services. Neither could I simply stop the services; doing so triggered a confirmation popup that required user permission.

Although it doesn’t block exploits at the network level, this is a sturdy firewall. If you leave its program control components in Auto-decide mode, it will do the job without a plethora of popups.

Ransomware Shield

Any time malware slips past your security product’s real-time protection, it’s bad. However, in most cases the malware doesn’t enjoy its freedom for long; the antivirus company quickly pushes out an update to smack down the zero-day offender. But that’s no help if the malware has already encrypted your important documents. Like many competitors, Avast offers an additional layer of ransomware protection. The Ransomware Shield component blocks all unauthorized modification of files in protected folders, and you can bet a ransomware attacker isn’t on the authorized list.

By default, Ransomware Shield protects the Desktop, Pictures, and Documents folders for all users. You can add or remove folders from the protected list. You can also add to the list of protected file types, useful if your important data files don’t fall among the default types.

When a program tries to modify any protected file, Ransomware Shield checks it against its cloud database of known clean programs. If the program comes back as unknown, you get a notification, and you can choose to block or allow the app. That means you can easily give the go-ahead if Avast blocks the brand-new photo editor you just installed. But if the warning is unexpected, you should block the app, and run a full scan for malware. Bitdefender Internet Security and Trend Micro offer similar protection against unauthorized file changes. Panda takes the concept farther, blocking unknown programs from even reading data in protected areas.

For a sanity check, I tried modifying text files in the Documents folder with a hand-coded text editor. Avast leapt into action, warning of an unauthorized change. It also blocked file access by a very simple ransomware simulator that I coded myself.

Next, I turned off all protective shields except Ransomware Shield, isolated the virtual machine from the network, and experimented with a half-dozen actual, real-world ransomware samples. Naturally it didn’t detect them as malware—I turned off that protection. But it successfully prevented them from harming my files. Two of them displayed their ransom notes, claiming they encrypted my files, but they lied; the files weren’t encrypted.

Spam Filter

Just about every early-days security suite included some form of spam filtering, because back then it was important. Nowadays it’s a rare user who doesn’t get spam filtered by their email provider. All the popular webmail providers do a good job, and business email tends to get filtered at the server. Having a local spam filter is unimportant to enough users that Avast doesn’t even install the antispam component until you request it.

The spam filter checks your incoming POP3 and IMAP email traffic, marking spam and phishing messages by modifying the subject line. If you’re using Microsoft Outlook, it filters any type of email account and automatically moves unwanted messages to the spam folder. Those using some other email client must define a message rule to divert the marked messages.

If you just click the component on the Privacy page, you get a very simple sensitivity slider. At the default Strict mode, it handles most spam but lets you decide on uncertain items. Slide it back to Relaxed and you get more spam, but need not worry about missing valid mail. Going the other way, to the No Mercy setting, you may find some valid mail tossed in with the spam. Your best bet is to leave this slider at the default middle setting.

The full set of spam configuration options still isn’t very complex. There’s another chance to set the sensitivity level, here described just as Low, Medium, and High. You may want to check the box that tells it to whitelist the recipients of your outbound emails, so you don’t accidentally block valid responses. There’s also an option to whitelist the entire domain when you send an email, but I’d leave that one disabled. Do you want to whitelist the entirety of gmail.com? You can also manually whitelist or blacklist specific addresses or domains, for example to ensure mail from pcmag.com never winds up in the spam folder.

That’s about it for settings. It’s quite a contrast with the eight pages of antispam settings in Check Point ZoneAlarm Extreme Security. Since most users aren’t likely to mess with the settings, keeping them simple makes sense.

Other Suite-Specific Features

As you peruse the Protection and Privacy pages, you’ll encounter a few more features unlocked by upgrading from free antivirus to this suite. Real Site is a tough one to see in action. Going beyond protection against phishing frauds, it aims to foil DNS poisoning attacks. This sort of attack hijacks the DNS servers that translate human-readable domains like PCMag.com into machine-friendly IP addresses. In effect, it creates undetectable phishing sites.

Antivirus researchers can’t just peruse the disassembled code of suspected malicious programs. They really need to let the shady file execute and watch what it does, but without letting it do any real harm. Their solution is to run the file in a sandbox, a virtual environment that lets the malware run but prevents permanent changes to the file system or Registry. You can run a file in this suite’s Sandbox just by dragging and dropping it. And you don’t have to be a researcher; the program points out that since files executed in the Sandbox leave no traces, «you can run a file without anyone knowing, or play games without having to worry about auto-saving.»

In theory, Avast’s on-demand and on-access malware scans should eliminate any data-stealing Trojans (along with other malware) before they can do their dirty deeds. The Sensitive Data Shield feature helps ensure that even if such a Trojan manages to run for a while before getting caught, it won’t find data to steal. You start by running a quick scan for exposed personal data.

My test systems don’t have a lot of data files, nothing like your own home or office computer, so I wasn’t surprised when the scan turned up nothing on the virtual or physical test machines. I went to my workaday computer and copied over a raft of sensitive documents. These included tax returns, forms for setting up a trust, an application for a Home Equity Line of Credit, and other finance-related forms. Even with this trove of sensitive data sitting temptingly in the Documents folder, the Sensitive Data Shield scan found nothing. I’m left not entirely sure of what it’s meant to do.

No Performance Drag

As noted, this is a full-featured security suite, integrating almost all of the expected suite features and then some. One might be forgiven for expecting such a product to suck up system resources and slow down performance. One would be wrong; Avast had no measurable effect in my hands-on performance tests. I ran scripts that measure boot time, the time to move and copy a big file collection between drives, and the time to zip and unzip that same file collection repeatedly. Averaging multiple runs before and after installing Avast, I didn’t find that it slowed things down at all.

Performance Results Chart

Webroot, Bitdefender, and adaware also exhibited no slowdown in my simple tests. Averaging the results of the three tests, quite a few suites came in under 10 percent. Few modern suites dare to slow down system performance by much, but I’m still impressed with no performance drag at all.

Not the Best Avast Suite

Avast Internet Security is a full-scale security suite, with antivirus, firewall, spam filtering, password management, and more. However, this suite shares a significant number of features Avast Free Antivirus, and it lacks full access to many of its apparent bonus features; Avast reserves those features for the top-of-the-line Avast Premier. If the free antivirus covers your needs, it’s a good deal. If you want everything Avast offers, with no holding back, look instead to Avast Premier. This suite is, unfortunately, stuck in the middle.

Bitdefender Internet Security and Kaspersky Internet Security represent the entry-level security suite for their respective companies. Both earn fantastic scores from the independent labs, and in some of our hands-on tests. Both go beyond the minimum features for an entry-level suite, and do include parental control a common feature that Avast omits. And we’ve named both Editors’ Choice for entry-level security suite.
