hidden folders

My Ad Aware SE has found about 100 files of spyware adware and worms in a file thats called something like C:\\_Restore or something like that. all the files end with a weird name like A0111923 and go in sequence (im guessing the names). the problem i have is that they are unremovable by ad aware, and invisible to other spyware removers. The folder is located win WINDOWS but its hidden from what i know, and i cant find it on search/explore. so how would i go about loacting this folder and deleting the files inside.

i dont know if this has anything to do with anything, but i remember Dave talking about how to get to hidden folders by creating a .BAT file or something. i dont know, im not too good with computers.

please help.

the whole A01ect. makes it look like a huge hard drive catalogue
it might be a back up of your hard drive or a hacker is using your comp to store files or stage attacks
