task manager disabled by admistrator

Resolution

This error is caused if the DisableTaskMgr restriction is enabled. To enable Task Manager, try one of these methods:

IMPORTANT: If this restriction was enabled in your system without you doing anything or without your knowledge, then it's highly likely that a Virus has blocked the usage of Task Manager in your system by enabling the DisableTaskMgr policy via the registry. I strongly suggest that you perform a thorough checkup of your system immediately. Steps listed in the Resolution section of this article helps you unblock the Task Manager, but that does not remove the Virus (if any) from your system.

Pls. read the methods here:

Yes, it's a virus known as Brontok, if you know how to create a registry file " .inf ", make one for yourself, name it Restore.inf or what you want, include the following inside your file.

This will enable again Task manager, Regedit, MS-Dos command line and everything Brontok disables, without forcing you to manually edit anything, avoiding the risk of damage to your registry.

Hope this help you and anyone that has the same problem.

I have a weird problem. Can you walk me through to fix my laptop please? I have a Windows XP Home Edition version 2002 Service Pack 2 with no anti-virus programs and 6 days ago after searching for 'roms' to download and finding nothing but POP UP WEBSITES. another browsing window from Internet Explorer popped up and it wouldn't close. So I tried Alt + CTRL + Delete and it said "Task Manager has been disabled by your administrator"

I tried searching for the worm, cookie or trojan by going to "RUN" "REGEDIT" And received "Registry editing has been disabled by your administrator". Then, when I went to check on my local disk 'free space' I noticed that the storage capacity kept on decreasing.

I'm not able to use Firefox as a browser, just IE and I'm not able to download anything through IE because every time I want to download something or an anti-virus it closes the window that will be used to download or my pc acts like if I hadn't clicked on the link to download.

I tried going to the sites you've listed to get my laptop scanned online and when I click, my machine doesn't do anything or sometimes it just shows a 'green progressing image' at the bottom of the browser on the status bar; like if it was trying to load the page but it's not.

What else can I do? I have a roommate who has a desktop PC and we tried uploading AVG anti-virus through her computer to my laptop; and it uploads well except that when I want to install the anti-virus the windows looks like it has been frozen and then, it shows an error message named "msiexec.exe - Application Error" it says "The instruction at "0x76c941b1" referenced memory at "0x76c941b1". The memory could not be "written". Click on OK to terminate the program.

Any alternatives besides re-formatting please?
