For those of you who use AVG, go here and see if it alerts on trying to download these. [eicar test files] http://www.rexswain.com/eicar.html It DID NOT for me, I wanted to make sure.... I tried AVG last week as a backup for my daughter's PC with PC-Cillin on it. I uninstalled it, made PC-Cillin as backup and installed KAV4.5 PRO as main RTM. If it could not catch those tests BEFORE it downloads, it's not a goer for me as far as I am concerned. Yes, they *may* be safe until you try ti execute them [AVG did alert when I dbl clicked them after dl], but that's not the point for me. AVGv6 FREE was the one I tried. Cheers, TAS edit: Just a side note in case some of you are very observant. The filename on KAV's alert does not say eicar.com.... that's because KAV renames the file with random letters/numbers and quarantines it so it's useless.
