I was useing my Hp laptop last week and i download a torrent it was windows Chicago which was made in 1993 (so they say) and i used Bit Torrent to fully download it. the next DAY i boot it up and the welcome screen loads longer and the following ERROR shows up:
"Security Warning!
Worm. Win32. Netsky detected on your machine.
This virus is distributed via the internet though e-mail and active-x objects.
The worm has it's own SMTP engine which means it gathers e-mails from your local computer and re-distributes itself.
viruses can damage your confidential data and work on your computer.
Continue working in unprotected mode is very dangerous.

Type: virus
system affected: windows 2000, Nt, Me, Xp, vista, 7

then when i click ok the computer finishes loading and instead of my desktop it shows a green screen with the words Your system is infected and some more............
