avast! Free Antivirus

Having earned the trust of over 180 million users worldwide, Avast Free Antivirus is easily one of the most popular security solutions. And there’s a reason for that: A free reliable utility with decent system requirements and nifty interface does a lot more than some of its paid competitors.

The core of the application is an advanced virus detection mechanism that both provides real-time protection from malicious elements and performs scans of available disks for viruses. And thanks to the transparent streaming virus database update system, the protection never falls off or gets weakened. Avast Free Antivirus offers only basic protection options compared with more advanced Avast products: firm protection against viruses and malware, security plugins for all major browsers and system scan for viral applications featuring a strong heuristic.

One of the most interesting options of the antivirus is a file reputation system that allows users to rank suspicious or non-safe files, so whenever you download a file from the Web, Avast Free Antivirus checks with the community data and determines the overall safety score of the file. And with another utterly helpful function, the Sandbox, the tool can virtualize running applications if it detects or suspect any threats coming from them.

The interface of the program is clear and intuitive; all functions are easily accessible and well illustrated which means using the tool is smooth and effortless even for a beginner user. Interestingly, the application allows a more experienced user of Avast Antivirus to help you remotely if you’re in trouble.

Avast Free Antivirus supports all Windows versions from XP to 8 and warns against literally all kinds of threats whatsoever. Protecting files and browsing; shielding dangers caused by P2P networks, instant messaging, scripts, and program’s behavior; and detecting an enormous number of possible risks - this toolset is definitely a must.
