Microsoft Security Essentials is fake. Well, it is and it isn't. Microsoft Security Essentials is a free antimalware protection program from Microsoft, but a new malware threat identified by security software vendor F-Secure is also masquerading as Microsoft Security Essentials. You want to avoid that one.

The new malware attack is distributed through a drive-by download as either hotfix.exe or mstsc.exe--both reasonably benign and almost legitimate sounding file names that might not raise red flags with some users.

Microsoft Security Essentials is a legitimate program, but don't be fooled by its drive-by-download, rogue antivirus version.The "alert" from the threat steals the Microsoft Security Essentials brand, including the little blue fortified castle icon. The software then displays a seemingly comprehensive list of antimalware solutions--including all of the top names that users are familiar with such as Trend Micro, McAfee, Panda, and Symantec-- and identifies those that are capable of detecting and blocking this nefarious threat.
