users of kazaa and msn messenger be on the lookout for yet another worm, don't download any file on kazaa with a developer of ' [SN] ', if you run the program you will get a false error message that says something about an attempt to read memory from 0xffffffffh or something similar.

its not malicious at all or poses a danger to your system if you become infected at all and only takes a couple of minutes to remove, it is indicated by a program running called .exe and also some other strange names (full list on mcaffee)

here is a link to mcafees site with removal instructions:
