System Lock 2011

System Lock 2011, or SystemLock2011, is a rogue anti-virus program that may spread throughout the Web with the aid of a trojan downloader (such as Trojan.Zlob or Trojan.Vundo) typically found on porn, warez, or similar questionable websites. System Lock 2011 is a clone of Security Tool and System Tool. Once the trojan downloader has installed on a users' machine, it will display misleading messages that look similar to Microsoft Windows system alert messages. These fake alert messages have titles such as "Critical System Error!" or "Your Computer Is Infected" which are meant to scare users into believing that their computer is in danger and they must click on the 'OK' button to get the "fix" from System Lock 2011.

As soon as System Lock 2011 is installed, it will perform a fake system scan that will result in exaggerated spyware reports and even more misleading warning messages will pop up encouraging users to purchase System Lock 2011's full version. It is advised to delete any popups or fake system messages related to System Lock 2011 or Trojan.Zlob. No matter how legitimate System Lock 2011 or it's website may look, you should not download or purchase the System Lock 2011 program.
