Disk Space disappearing

Hello everyone. ONe of my computers is acting like the disk space is disappearing. I am not sure if there is something causing this or if it may be an early indication of a disk failure. At one point, the disk (36GB) reported that it was completely full with only about 30MB of space left. After examining the system to try to figure out what was going on it appeared normal again with only about 9GB of space in use. As time goes by it appears that the disk is slowly filling up again. It is reporting about 7GB free now. I ran ad-aware and spybot and found nothing unusual. Here is a hijack this log after I have tried a couple of things with no luck. Any help would be appreciated.

Thanks,
Rob

I think I have figured this one out, mostly, and I think this line in my log file is the cause. C:\WINDOWS\inf\svchost.exe I noticed while my disk space was being eaten up that the CPU was at 100% and an instance of svchost.exe was doing it. I was able to stop it and then my space came back. Searching the drive for svchost, I found the compressed file in the I386 directory and one in the Windows\System directory where it belongs which was about 13K. I also found one in the Windows\INF directory that was 576K and a file called SVCHOST.EXE-37C64DE2.pf in the Windows\prefetch directory. I was able to delete the svchost.exe file in the INF directory after stopping another wild instance of it in task manager. My problem has not come back since deleting this file. Is anyone here interested in the file to examine it since this was not detected by anything I tried? The file properties version information makes it look like a microsoft file aside from some suspicious looking characters on the copyright line that got me thinking. Could there be some more clean up I need to do besides just deleting this file?
