Awoke feeling inexplicably paranoid about computer security. Soon discovered my freeware versions of AVG, Spybot and Ad-Aware had all been superceded. And that an individual who SHAN'T remain nameless - PG! - had registered one of them to "Magic: The Gathering" creator Richard Garfield. Downloaded the new programs on the block, updated their respective databases and performed exhaustive (ie. looooooong and boring) scans. A dozen aberrant but probably benign files were zapped before my PC was given a clean bill of machine health. No idea why I neglected this stuff for so many months - it's a wonder a Nigerian e-mail scammer isn't partying hearty on my credit card.
