My Security Shield removal instructions (Uninstall Guide)

Tell your friends:
My Security Shield is a piece of malware that pretends to be a legitimate anti-virus software. Actually, it's pretty generic looking rogue anti-virus program that may arrive on the compromised computer as a manually install or may be downloaded by other malware. Usually, My Security Shield is promoted through the use of fake online scanners and infected websites. It prevents other applications from being executed and displays fake security warnings. MySecurityShield reports false scan results and states that your computer is infected with various viruses, adware, spyware or other malware. As a typical rogue anti-virus program it will prompt you to pay for a full version of the program to remove the infections. It goes without saying that you should uninstall this virus from your computer instead of buying it. Unfortunately, it's rather difficult to remove this fake program from a computer, thankfully we've got My Security Shield removal instructions to help you. Please follow the removal instructions below.

While the rogue program is running, it will flag harmless files as malware infections. In fact, My Security Shield drops several files on the system and later detects those files Trojans, worms or other malicious software. This misleading application adds itself to the list of programs that start automatically when Windows OS starts. It will hijack Internet Explorer and other web browsers. It may display search results from instead of Google. And of course, it may block safe security related websites and legitimate anti-virus and anti-spyware programs. Last, but not least, you wouldn't imagine a rogue program without fake security alerts and pop-ups from Windows taskbar. My Security Shield has it all. The fake program may display any of the following warning messages:
Warning! Virus detected
Threat Detected: Trojan-PSW.VBS.Half
Description: This is a VBScript-virus. It steals user's passwords.

Ran Malwarebytes twice (afer updating it), but Security Shield is still on my computer.

Security shield messes up all of your computer processes as I was to discover. Don't bother trying to download any removal tools. They probably won't run. Simply restart your computer and keep tapping F8 until the black screen appears. Select safe mode with networking and then press enter.
When windows starts, click start, select programs, accessories, system tools, and then system restore. This should only take a few minutes. It completely removed Security shield from my computer. I hope it works for you. Good luck...

I appears that Jonathan's method worked for me as well. Even better since I could even get my internet to come up to TRY to download a remover. Thank you, Jonathan!

Some of these fake anti-virus programs also remove system restore from safe mode. At work what we do to overcome this problem is to use a CD called ERD commander, it is a boot cd that is able to run a system restore from the CD. This is the quickest way of fixing the problem. It is also wise once the virus has been removed to disable system restore and enable it again. This is a measure to make sure that it can't escape the system restore files and reinfect your computer.

System Restore in the Safe Mode Works. I tried other programs that did not work but this did and it worked quickly!
