A virus masquerading as a new beta version of Microsoft's MSN Messenger has begun circulating, antivirus company F-Secure said on its blog Tuesday.
The virus, which F-Secure calls Virkel.F, comes as a file called BETA8WEBINSTALL.EXE that can be downloaded from a Web site. Running the program installs not a new MSN Messenger beta, but rather a virus that sends download links to a computer user's MSN Messenger buddies. The virus falsely labels the link as "MSN Messenger 8 Working BETA."
It also connects your machine to a botnet server," F-Secure warned, meaning that a person's computer can be controlled remotely to attack other machines or send spam.
Viruses are becoming more and more sneaky...as Threi says, if the link doesn't point to MSN Messenger's site then don't download it. Simple.
