Sorry to hear that Fran. You have my total sympathies (although I am not sure what you do exactly to blow up a hard drive).
Anyway, with the use of some new virus software I have discovered the root of all evil lurks within my computer: the KLEZE WORM. I cleaned up over 200 corrupted files, but could not remove the actual virus itself. The software I have (Panda) is an online wossname and is apparently coming up with a solution in the next 48 hours.
I hope so because I want my computer back. As things stand with several hours of effort I can get online for just long enough to send maybe an email or two before everything comes crashing down!
