Antivirus ...revisited - More programs to help fight the fight.
I know you never get tired of information that is about antivirus stuff. Well I just have two for you. Avast (http://www.avast.com/eng/down_home.html) and ClamWin (http://www.clamwin.com/). Both have free versions (ClamWin is actually open source), both seem to have no noticable conflicts with AVG from Grisoft (reviewed below). Avast has a really cool interface, I almost thought I accidently downloaded a MP3 player :). Both of these programs allow you to integrate them into software on your system, like Outlook and MS Office programs. This is great but be aware that the programs will open more slowly. Small price to pay for those of us who roam the internet and have our systems on broadband.

I haven't gone into the details of either programs, I have left you to do that when you visit their sites.

Please note that ClamWin Free Antivirus does not include an on-access real-time scanner, that is, you need to manually scan a file in order to detect a virus. Microsoft Outlook Addin, however will delete a virus-infected attachment automatically.
