Do you know you can hide any specific Partition from My Computer (without deleting all your data)? Well Yes, you can in few simple steps. I'm showing steps that how I hide D: Drive from my Computer. But few precautions, that you can't hide C: Drive, and my suggestion is don't forget to show it back after you think its time to show (steps to show it back also included). One thing, if the partition is being accessed by any process then you can't hide it, and if you are facing problem in hiding it and sure that no program is accessing it, its because of virus undoubtedly.
