Today I opened my PC & was using it normally and then I tried installing a new game but the setup didn't start, Then I tried starting utorrent but that also didn't open. Now I opened Task Manager to find out what's wrong. I found 2 thing wrong.
1) ClamAv Or clamd.exe was taking approx 350MB of ram (Usally 0.4 - 40 MB)
2) The process sanotifier.exe was open approx 20 Times (Usally 2) Then ram uses of each was approx 500KB.
These are the process stopping the software because the notification was not shown the software were unable to open.
As I found that I tried disabling the whole av but still nothing happened then I restarted the PC and now its normal. I didn't knew what caused that. I tried doing the same thing after restarting but it was all fine. I don't know the cause of the problem.
