avast! Free Antivirus
The install was relatively quick, with the option to install Google Chrome and setting it as the default web browser. I guess I can’t complaint much about this since it is a free antivirus after all. As soon as the install finished, avast! quickly updated itself in the background just as the main interface was loading up.
Overall avast! looks very simple and intuitive, with the main screen showing the currently activated features and further access to the features on the left tabs panel. On idle, avast! uses up around 8mb of system memory, while running full scan takes roughly 18mb of memory! The program version tested was 5.0.677 and virus definition version was 101226-0.
Since this is a free antivirus, it doesn’t come with the built-in firewall, so Windows Firewall needs to be enables, or any other third party firewall. The second issue, which again is not really a big deal considering this is a free AV, is that you have to install Flash Player 10.1 to check out the statistics graphs.
The first complete system scan took a time of 6:56 with 166276 files canned, while the second complete scan took 3:38 to scan 166255 files. During scan, avast! used 1 core and 2 threads using roughly 20% of CPU power continuously. That’s pretty impressive scan times considering how low the load on the system is.
As for the malicious website test, I looked at a Trojan file where avast! outright blocked the page from even loading.
