scan not working after upgrading to windows 10

i upgraded my system yesterday from windows 7 to windows 10 but i it has issues with f secure. first f secure showed malfunction and asked to restart. after restart warning disappeared but i found that scan is not working. also after upgrade microsoft defender automatically started and it detected some default tab registry key. i removed it. than started f secure. but after hitting scan button i came to know that scan is not working. i tried several ways. full system scan right click scan but none worked. also a strange thing is that hitmanpro too is not able to scan. but malwarebytes worked absolutely normally. i think it is an issue with system not with f secure only. but still any help would be good. i saw different  discussions here related to windows upgrade so i guess this issue too can help someone if he/she ever comes through this kind of issue. i have already raised support ticket. waiting for their rply.

    one more thing. I was not able to download cleanup tool/online scanner too. but may be it has something to do with my internet bandwidth. and other strange thing i observed is that before restart i was not even able to turn off all security features. but after restart that problem seems to be corrected.

    Have you fully disabled Windows Defender? Apparently it's more persistent in Win10, so F-Secure may not automatically turn it off. Try that first, as it may be causing a conflict.
