Help with identifying these temp files

For the last few months I've noticed that my Temporary folder is filling with ~df files, that is, small files with names such as ~df7958, ~df8aa8, ~dfddba, etc. They're all sized between 2k and 8k and I can't glean much from opening them, it's usually meaningless (to me) garble, although strangely one did have some readable text from my internet home page, a word forum. They seem to be created once or twice a day, and I have to delete them myself, all but the ones with a current date as these refuse to be deleted until the next day.

I've run my AGV antivirus, Hijack This, Adaware, Spybot Search & Destroy and Swatit Trojan Finder but they all give me a clean bill of health.

Any ideas as to what these files are? My computer is running fine, so I don't think they're harmful. I'd just like to know what they are.

 

Do you have SpyGuard installed?

SpyGuard ~DFxxxx.tmp files in My TEMP Folder :-(

 

You can safely delete the contents of the C:\Windows\Cookies; Temp and Temporary Internet Files at any time. A good way is in Safe Mode.

(tap F8 five times per second during a restart; Choose option number three (3) in the Windows Startup dialog box using the arrow keys below the Delete key, and strike the Enter key; Click Ok when prompted).

 

You hit the nail on the head, virtualme! Thank you for putting my mind at rest.
