In my system if i open c: drive it opens. But the other drives are not open when i click by mouse. It shows "OPEN WITH" window. Now, i am opening this drive by clicking mouse right button and click "explore" only.
I don't know how to solve this problem. I have internet connection in my system and i have "Symantec Endpoint Protection' anti-virus system.
I checked virus also but there is no virus infected.
