Sober Email worm
A virus which poses as a security fix from an AV firm is the latest menace to assault Windows users.
Sober typically spreads by email. The viral messages it generates have infectious attachment names such as typically anti_virusdoc.pif, check-patch.bat, playme.exe and variable English and German subject lines. A full list can be found in an advisory from Finnish AV firm F-Secure.
