Specs: Windows XP
Just for anybodies info as I searched hi and lo for a solution.
I had a pc infected by My Security Shield which is a rogue programme that takes over your PC until you buy it and then its actually no good.
It disables task manager and also will not allow you to install another AV even if you think you've removed it.
The seemed to be lots of posts about taskmanager disappearing but no-one fixed it.
I found that the program had modified the key entries in the registry for taskmgr.exe.
There are three of them
In the first binary value (0) it modifies the entry after the last 28. It should be 28 0A 01but the infected pc was 28 01 0A. Changing them fixed the problem.
There were also a few entries showing DisableTaskmgr but they didn't seem to make a difference.

Hi Guys
In Regedit search for "taskmgr.exe" is the easy way, then you don't get all the other entries for taskmgr.

1st is KLM\SYSTEM\Controlset001\Control\Nls\MUILanguages\RCV2\Taskmgr.exe

2nd is KLM\SYSTEM\Controlset003\Control\Nls\MUILanguages\RCV2\Taskmgr.exe

3rd is KLM\SYSTEM\Controlset004\Control\Nls\MUILanguages\RCV2\Taskmgr.exe

4th is HKLM\SYSTEM\Controlset\Control\Nls\MUILanguages\RCV2\Taskmgr.exe

There are 4 on this PC the number of entries seems to vary. The Binary value to change is the one beginning with 52 04. Its number 0 on my PC. when you double click it you will see the last 28 0A in the third and fourth columns is the wrong way round compared to the others. Hope this helps R.

Hi Tufenuf
I tried those two fixes first and they did not cure this problem. There were DisableTaskmgr entries there which I corrected as per your fixes. Maybe you need to apply both fixes. It as when I was trying them I noticed the changes to the Taskmgr.exe entries mentioned above when compared to a non infected PC. So I had already corrected the DisableTaskmgr entries. Chrs RC
