As of now, I removed it... But there was a DLL file in my system32 folder trying to write the same file in the same place continually, and failing every time. I found it with process monitor because I was wondering why my computer was running slowly. When I forcefully deleted the DLL (It was in use, naturally...) it BSoD'd the computer. On reboot everything was fine.
I can't remember the name of the DLL, but I google'd it before I deleted it and it came up with 0 results, so I don't think that the name of it would matter much. I do remember that the name was 8 letters, all caps, began with DF, and was in use by firefox, explorer, msn messenger, and winlogon. Unfortunately when Firefox crashes, recent searches aren't saved.
Apparently Trend Micro didn't catch it, so either its a new one or Trend Micro missed it. Although I would like to note that Trend Micro was writing something to its log every few seconds, but when I checked, that particular log was not in the Trend Micro logs folder, which is all the more annoying. Trend micro is also not writing a huge number of logs now, like it was before.
Oddly, even an undelete utility didn't find it! Despite the fact it found my data-shredded passwords from 3 months ago, anyway.
It's like just gone
In any case, the reason I am posting this topic is because I want to know if there is any other malware out there that does this sort of action, in case I happen to get it again, I'll know what to look for. Even if it's not known, I'd like to know what it was trying to accomplish by writing the same file over and over, if anybody out there might have an explanation. Thanks.
