I too didn’t bother with Prevx, especially after some of the posts in the Prevx threads.

I also agree that you can go too far in the security stakes and agree with Sasha, a good AV (avast!), a good firewall, Ad and Spyware blockers. I also do regular image backups (weekly) of my C & D partitions. So if things get really screwed out, restore the latest image and latest data files, email, address book, favourites, etc. (backup daily).

Above all else a high degree of common sense, is probably your greatest asset.
