I don't bother with antivirus software. One of the reasons I'm using Linux is because it's reasonably impervious to viruses, and totally impervious to spyware. And I don't use Word or Excel-format files, either. I have OpenOffice at work on my Windows box and at home on my Linux machine, all so that I don't have to worry about Microsoft Office macro viruses.
In retrospect, everything is funny.
