i have a USB and it has these files that wont go away. the directory is D:/a/r8/b/c/d/e/f/g so i'm assuming that its some kind of virus or something. i cant delete any of them for various different like: the file name is not valid or too long, could not find the item, and some are system files that keep coming back every time they are deleted. the extensions are things like: .OLD, .OL@, .BLD, .OHD, .F(femalesign)@, .JDD, .KD@, and it goes on and on. it started with only three then there was five then i stopped trying to delete them for a month and now there is 48 of them and its taking up 754 MB of space on my 2 GB USB. is there anyway i can get rid of these? if not can i just wipe the drive completely and still have it be useable? if needed i will post the entire list of files. it's taking up a lot of data and i cant get rid of it.

oh, and i'm running windows 7 starter edition with latest update, and another with windows 7 home edition also latest update,
i dont know whether it was one computer or the other or both causing it. PLEASE HELP!!!
