Yeah it's the Netsky/Mydoom virus anyone who gets infected it sends out emails to any email address it can find on your computer, but it uses peoples names out of your address book as spoofed email addresses and names (basically comes from your computer but puts other peoples details on it, therefore they will email the return address saying WTF?? When it wasn't them in the first place.)
Everytime I get email through Outlook express, Vet Antivirus goes nuts and 2/10 emails I get are Netsky infected emails!!!

Bastard virus makers, I got infected by Mydoom a while back along with some other virus and I lost everything on my computer wasn't a happy camper
