akala,

Can you take a screenshot of all those files so that we can see what's happening?

Had you opened a newly downloaded file just before this started happening? If so, can you remember what type of file you'd downloaded (don't name the file, just tell us what type it was - wma, mp3 etc)?

There's a fix for the popping up thing here, you can give it a try. The original poster in that thread also did a system restore after running the BFU & found that it helped...so give that a try as well.

I'd also update your AV & scan your computer. There's another link in that thread with further links to online scans if you want to try one of those. Please let us know if a scan finds any malware. If you're still having problems, go to one of the specialist malware removal sites mentioned in that thread.
