Avast Free Antivirus

Avast! Free Antivirus 7 continues to push the envelope of top-shelf free security features with hybrid update tech, file reputation analysis, and more. It's independent benchmarks are a bit weak, but more than 150 million people trust Avast to keep them safe.
 Looking to compete with both paid and free security suites, Avast wants to create a unified approach to your computer security. Long gone are the days of the quirky interface. Avast is accessible and robust, with an impressive list of free features and strong, though hardly stellar, performance benchmarks.

Avast has improved its installation process so it's faster than before. It's not the fastest on the market, not by a longshot, but a standard installation took us about three minutes.
Some items of note during the installation that will come up later in the review: to avoid the new Windows 7 and Vista desktop gadget, or the new WebRep browser add-on, you must choose the Custom install option and uncheck those here.
Automatic installation of these features is frowned upon, although Avast does provide a clear method for uninstalling them. It's just not as simple as a check box that gets its own installation window, since you have to go through the Customize menu, which makes the auto-install sort of surreptitious.



Avast 2012, aka Avast 7, includes several new features that directly impact your security. One of the biggest changes is a hybrid update technology that pushes out updates in real time. Because a full database update isn't required, Avast users will get their security updates much faster than before. Full database updates will also be pushed out, just not as frequently.

Another important security change introduces a file reputation system for evaluating downloads. This tech has existed for a couple of years in paid security suites like Norton, Kaspersky, and Bitdefender, AVG, but Avast is the first free antivirus to offer it. It leverages community data from Avast's enormous active user base to help determine if a file is safe.

The free version of Avast is arguably the most comprehensive set of freely available security features on the market. There's a reason these guys have more than 150 million active users (at the time this review was written). The antivirus, antispyware, and heuristics engines form a security core that also includes multiple real-time shields. Along with the new features, it's got an AutoSandbox for automatically walling off suspicious programs; a full complement of shields that guard against scripts, P2P networks, instant messaging, and potentially dangerous program behavior; a silent/gaming mode; on-demand boot scanning; and a healthy output of statistics for the data nerds.
As far as Avast's impact on system performance goes, in a real-world test Avast completed its scans in a timely yet not blazingly fast manner. A Quick Scan took about 20 minutes, and the Full Scan took 59 minutes. RAM usage was surprisingly light, with Avast only eating up about 16MB when running a scan.

The latest version of Avast! Free Antivirus 7 kernel features outstanding detection abilities, together with high performance. You can expect 100% detection of In-the-Wild viruses (viruses already spreading between users) and excellent detection of Trojan horses.
The avast! engine also features outstanding unpacking support. It can scan inside the following archives: ARJ, ZIP, MIME (+ all associated formats), MAPI (Outlook pst files), DBX (Outlook Express archives), RAR, TAR, GZIP, CAB, BZIP2, ZOO, ACE, ARC, LHA/LHX, TNEF (winmail.dat), CPIO, CHM, RPM, ISO, 7ZIP and SIS. It also supports a number of executable packers (such as PKLite, Diet, UPX, ASPack, PeShield, FSG, MEW etc.).

Resident protection (the real-time protection of the operating system), is one of the most important parts of an antivirus program today. Avast! Free Antivirus 7 features a powerful resident module that is able to detect a virus before it has any chance to infect your computer. avast! Home Edition contains resident protection of the computer file system and a resident module for e-mails and news.
Avast features a module for the protection of IM (Instant Messaging, "chat") programs, and a module for the protection of P2P (peer-to-peer) programs. The list of supported IM and P2P programs is extensive with more than 30 programs currently supported.
