What is Windows Optimization & Security:

Threat Classification: Rogueware

Windows Optimization & Security is a malicious rogueware that is a part of the Fake Microsoft Security Essentials malware family. Windows Optimization & Security pretends to be a legitimate antivirus security program and produces fake Microsoft Security Essentials messages that your system has been infected with an Unknown/Win32 Trojan. It will then open a pop-up window and initiate a FAKE scan, which will confirm, that your computer is infected with a Trojan.Horse.Win32. Then the infection will suggest you to install the Windows Optimization & Security. 

The exact text of the pop-up is:

Threat prevention solution found

Once you’ve clicked on the OK button, the infection will download and install Windows Optimization & Security and restart the computer.

Furthermore, Windows Optimization & Security will try to kill any software you try to run on your computer.

This may be caused by severe malware infections.
Automatic restore of lsass.exe backup copy completed.
The correct system performance can not be resumed without eliminating the cause of lsass.exe corruption.

Name: c:\program files\firefox\firefox.exe
