My PC started behaving in a very strange manner lately: sometimes the internet connection would just fail (I can't get through to my DHCP server and get a new IP address), even though it says that it's connected. After a couple of minutes or so, the PC freezes, and something starts using the CPU so aggressively that I can't even open task manager or any other process viewer and see what the [bleep] is happening! Then, it starts to write to the HDD. The first time this happened, I remember I had about 7GB of free space on the disk, and since the pc froze, I reset it and I got a "Critically low disk space" baloon tip, saying that I only have 4MB of free disk space left!!! 4MB!!! So I deleted some stuff, and I freed about 5 more GB. The next time this happened, I only had 14MB left! Now, doesn't it seem strange? I ran a full system scan, using F-Secure AV, with newest updates, and found nothing. I scanned the system with F-Secure BlackLight and found nothing. I ran a scan with AdAware with newest definitions, and it found a couple of trojans, but this odd behaviour did not stop. You guys are my only hope of restoring my PC, because formatting the disk drives is NOT an option. I did my best to clear the Temp directories, so that the HijackThis log wouldn't be longer than necessary. And here it is:

Any help would be very much appreciated. Btw, I read the "Read this before posting a HijackThis log" topic.
