Microsoft announced on Wednesday
that malware writers are creating malicious applications with a similar name, look and feel to the company's legitimate security software (Microsoft Security Essentials
) -- a popular and long-used method of preying on inexperienced users. The fake antivirus is called "Security Essentials 2010" and contains the Trojan Win32/Fakeinit
Once installed, the malware downloads and installs a fake scanner that monitors processes and terminates ones
it doesn't like, claiming they are infected. It also lowers some security settings in the registry, and changes the desktop background to display the warning seen below while modifying the registry to prevent the wallpaper from being altered.
