Lsass virus, also known as the Sasser worm, is a dangerous malicious software application that completely blocks your computer’s internet connection and uses it for other purposes. The Sasser Worm does not require you to visit any specific websites or to download any files for it to infect your computer. All it needs for the Sasser worm to attack your computer is for your firewall to be down.
The Sasser worm exploits this security weakness to the fullest and enters your computer through the internet connection and establishes itself. Once installed on the system, the Sasser worm causes dialog boxes to appear that warn you that your computer will shut down in 60 seconds. It also blocks certain websites and drastically slows down your internet connection. The Lsass virus is known by this name because it attacks the Lsass.exe process of Windows which is the process that controls the management of internet traffic on the system. Lsass.exe also handles authentication for your system, and contains all your login information such as usernames, passwords and banking information. The Sasser worm disables Lsass.exe and takes over its operations, and also steals your personal information.
