Windows Defender: "" this operation has been cancelled due to restrictions in effect on the computer, contact your system administrator ""

original title: windows Defender

I am a beginner and need help. I uninstalled net protect + because it wasn't, not with BT which were unnecessary, but thanks to a member of the forum. Net + had problems trying to reinstall Protect so therefor I installed internet security essentials and now windows Defender does not work! When I try to open the message reads "this operation has been cancelled due to restrictions in effect on the computer, contact your system administrator" can someone help me with this problem. The system is windows vista Home premium.

Have you installed Microsoft Security Essentials (MSE)? If so, you need not and should not run Windows Defender.  MSE does all what does Windows Defender and much more. Boulder computer Maven
