A very fast and effective free virus scanner produced by avast.

A review by Tina de Pierre

avast! Free Antivirus is the latest update to the popular free version of the Avast suite of AntiVirus products.

Avast Anti-Virus is the perfect antivirus solution for those that surf the web and send emails. It's optimized for Internet Explorer 9 [and IE8] with Scriptshield. The team has added new advanced capabilities not normally seen in anti-virus software and exceeds expectations for a free solution and infact for professional paid solutions.

Avast can scan directly from the command line prompt, includes both Antivirus and Anti-spyware, includes a Boot-time scanner and can also scan files in real-time.

Another standard feature is auto-sandbox which the program will automatically send malicious and/or suspicious files.

This newest version sports a brand new interface and was rated by AV-Comparatives.org as a 5.0 for speed, faster than the other top 20 antivirus programs tested, hands down!
