The full system scan I did today took around 2 hours to complete, but as of now (another 2 hours), it's still stuck on "cleaning in progress". I'm not sure if it's even doing anything because the CPU usage light doesn't reflect it. Did anyone else have this problem, and know what's happening? Should I just let it keep "cleaning" or just force quit it? It's funny because I didn't even get to see the results of the scan or choose what I want to do; when I came back to check it was already on "cleaning in progress".
