I am having a microsoft folder in the location C:\Program Files\Microsoft after startup. When I go in the folder then there are 2 other folders. I dont know what happened that out of nowhere this folder is now opening. This folder should start to launch after a small power failure just recently. When I turned on my pc, this folder popped up. I am able to close the folder but I dont want to do that everytime my machine boots up. Can anyone tell me how to stop this thing? Thanks. Also, I have installed Microsoft Security Essentials, could that folder related to this antivirus?
