My friend (who I help with his computer from time to time) very recently (as in, 10 minutes ago) discovered some oddly named folders at the top of his C drive. An example of these folder names is:
He can't access them, open them or anything. In fact, he doesn't have permission to open it, with the only permission allowed being from "system" even though he is his computers Administrator. He scanned with Norton and it was given the green light that its ok.
He has, understandably, freaked out and I think hes going to go overboard with system restores.
Related to this, on my older computer (which is mostly dead, hardware failure on a gigantic scale) I had folders that were named in a similar fashion, the difference being, I could open them. They contained an odd text file that when I clicked on it, windows gave me a message along the lines of "Don't touch this if you don't know what you're doing, it MIGHT be important".
Is this a virus, spyware, data corruption, fragmented files, or just an harmless oddity that can be resolved easily? My friend is running N360, latest updates and everything.
Edit: Got posted as a wall of text.
I googled this to the best of my ability, I'm not sure if I could have searched this particular question any better, but the most I found was; various notes to old XP viruses, a few trojans that like to drop thousands of txt folders in a computer, and what appears to either be a backdoor or some one managing to shred their OS boot files.
Edit 2: The files on my older computer are "BAK" files. I can only guess that he has the same BAK files on his as well.
