Hi

 

I have a windows Vista system

 

I cannot open Avira Anti Virus or Malware Bytes Anti Malware, I get an error saying "This program is blocked by group policy" in normal mode.

 

I have tried numerous things, such as running Malware bytes in safe mode, which found nothing, and ran Spybot search and destroy again, this also found nothing too. 

 

I honestly don't know what to do next, at the end of my tether.

Hello

 

What happens if you try and run these programs as Admin? Right click on Avira -> Run as Admin is this PC a work PC or a Home PC?

Hi

 

Exactly the same thing, the "This program is blocked by group policy. For more information, contact your system administrator" comes up.

Hello, and welcome to Bleeping Computer

What version of Vista do you have? It seems that a Software Restriction Policy was set for those programs. You can look at the Software Restriction Policies with the Group Policy Editor but it is only available in Vista Pro, Ultimate, and Enterprise. You can access Group Policy Editor by typing gpedit.msc in the search box and pressing enter. If you have a Home version of Vista then I believe you may have been infected by some form of malware and should start a new thread in the "Am I Infected Forum"

 

Malwarebytes has a download called Chameleon that will let you check for malware on an infected computer.

Are these the only two programs with the problem. Create a new user and see if you can run avira and malwarebytes.

Try to uninstall Malwarebytes, reinstall and see if you get the blocked error. You may have to do the uninstall in safe mode.

I am not sure what the problem is. In the search box type regedit. Double click it and go to the following key.

 

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Safer  

 

Right click Safer and select Export. Save it to the desktop with a name you choose. Right click the saved file and select Edit.

 

In the menu bar select Edit > Select All    Then Edit > Copy  Paste the results to a text file and attach it in your next post.

 

Edit: I will be gone until tomorrow. Getting tired.
