I received the following virus in my email from marketing@propun.com.au...
Name of File: it_.exe
Type of File: audio/x-wav
Scan Result: Virus W32.Klez.H@mm found. File NOT cleaned

Whoever sent it, thanks! Others beware.

Unfortunately the virus sends mail from an infected computer using any address in that computer's address book/or mail. The sender of the virus may not even be aware their computer is sending out the mail, using many names as senders.
We have received the same mail ourselves.
Our advice is to have up to date virus scanning which should pick up a common virus like that.

I placed two sites for those who are after free yet effective antivirus software in the systems section of this forum.

try this site to clean it
