Well I am sorry for the typo error its called win32\Deborm.Q virus , and yes the message was a Netsend messenger , but the sender was with the same name as that of my comp.
The message , file ~2.exe detected on a user's folder on my comp, but that user has never used my comp ( I am talking of the comp I used in office ). And I havent used a floppy either . That is why I am puzzeled as to how can the worm get into my comp.
Anti virus has repaired the file, but the questions that are baffaling me are :
1. How can the messenger service reported that a user's folder was infected when infact that user has never used my comp.
2. I havent used folppy since a year on my comp , my mails are scanned by antivirus s/w so what else can be the way in which worm sneak into my comp.
