The default Windows directory (e.g. C:\Windows for Windows XP)

 

Thank you. That is how I saved my problem with windows security center, nowI have only one problem... my computer is fresh formated and i've installed nod32, now my wsc says that there is a more than one antivirus installed.
What to do?
Tnx

 

If you have NOD32 and something else , uninstall the "something else" .
If you have NOD32 only , did you other security product before

Otherwise , the reset of the WMI should have helped.

I don't have something else, only nod32

 

You must be completely sure that it is NOD32 only installed as antivirus (no other AV) . You must also be sure that if you had any other AV installed before , all leftovers are completely removed.

If the above conditions are true , then "repair" the WMI as suggested by Blackspear/Agoretsky in the above link or use this procedure:

After restart , the machine might take some more to load , this is because of the WMI service starting again and "taking some info" (let's say it so)
In step 5 , note that the part C:\ might differ if you have installed Windows in partition with different name .

 

Should you still have Security Center issues , just open Control Panel -> Security Center -> "Change the way the Security Center ..." and uncheck Antivirus protection . Confirm with OK
