MSN Messenger trojan

Just read the news, there is new MSN Messenger trojan that is spreading now. Be aware of it.

The Trojan is an IRC bot that’s spreading through MSN Messenger by sending itself in a .zip file with two names. One of the names includes the word “pics” as a double extension executable—a name generally used by scanners and digital cameras: for example, DSC00432.jpg.exe. The Trojan is also contained in a .zip file with the name “images” as a .pif executable—for example, IMG34814.pif.
