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.
