Vista error "this operation has been cancelled due to restrictions in effect on this computer. Contact the administrator of the system to you. When you try to open Avira Antivirus and Windows Defender".

Whenever I try to open Avira Antivrus and Windows Defender, I get this message: "this operation has been cancelled due to restrictions in effect on this computer.  Please contact your system administrator. "I am the administrator and I have not set restrictions.  It worked, but started recently and I can't find answers.  All solutions?

Hi I_GHall

 

It seems that you receive the message you want to software conflicts. I suggest you try to disable either the Avira antivirus and windows defender and then check if the problem resolves.

 

If you disable any security software for troubleshooting temporarily, so don't forget to activate after troubleshooting is completed that your computer will be at risk.

I hope this helps.
