The Malicious Software Removal Tool (MSRT) is a small program Microsoft pushes out to computers on Patch Tuesday to clean out a list of malware. On this month's Patch Tuesday, Microsoft added scans for a malware file that masks itself as security software, and it found plenty of copies.
Win32/FakeSecSen has gone by various names, including Micro Antivirus 2009, MS Antivirus, Spyware Preventer, Vista Antivirus 2008, Advanced Antivirus, System Antivirus 2008, Ultimate Antivirus 2008, Windows Antivirus, XPert Antivirus, Power Antivirus, and Ultra Antivirus 2009. Furthermore, it is skinnable, so each of these variants has a different GUI, although the basic functionality is the same: bother users with warnings of malware until they pay up.
