I bought Nod32 yesterday and was startled at something I found in a list in the program settings. Nod32 users can see the list in question by opening Nod32, going to IMON, clicking Setup, then the HTTP tab, then the Client Compatibility button.

This is apparently a list of files on my computer that have accessed the Internet. Looking through the list, I found something that I thought was kind of suspicious:

User Agent: IS Download DLL
File: is-9HEIL.tmp

I ran deep scans this morning with fully-updated copies of Spybot S&D, AdAware, and Windows Defender. They all came back clean. I also ran RootkitRevealer, which also detected nothing unusual.

Now for the part that either makes me feel a lot better or a lot worse....

This morning, the first thing I did when I turned on my computer was check Nod32 to see if that is-9HEIL.tmp file was still in that list. It was. After checking the list, I ran the scans mentioned above, updating each of the applications first.

After running the scans, I checked the list in Nod32 again. To my surprise, I found is-9HEIL.tmp still listed, but right below it was another similar file:

User Agent: IS Download DLL
File: is-JCD3A.tmp

I couldn't find this file on my computer, but I did find a prefetch file for it (which I have saved and can probably send to someone if they're interested in seeing it).

I immediately ran HijackThis, but the log looks pretty normal to me. (Pasted it below.)

So I guess my question boils down to a pretty simple one. Is there any legitimate reason for temp files to be created, access the Internet, and be deleted? If so, I can probably count on my computer being okay. If not, I may need to keep checking.

(FWIW, I consider myself a fairly small attack target. I'm behind a NAT router, all ports stealth, no port forwarding or DMZ. I use Firefox and only visit reputable websites. I'm not a downloader and I try to keep my computer clean. No filesharing goes on here, no dodgy websites, etc. So I would think my risk is pretty low.)

Anyway, here's my HijackThis log:
