[JHY-IC]

Recently, I've noticed that my hard drive space keeps disappearing. I check it frequently by opening the DOS Command Prompt and entering the 'DIR' command.

I've watched my hard drive loose about 800 Megabytes.

Here is a list of actions that I have performed thus far in an effort to locate the problem:

Cleaned out all temp folders (C:\Windows\Temp, C:\Windows\Prefetch)
Ran Windows Disk Cleanup
Ran A-Squared
Ran Microsoft AntiSpyware
Ran Registry Mechanic
Ran System Mechanic 5 (Junk file removal, cleanup your tracks, etc.)
Ran TuneUp Utilities 2004
Ran Ad-aware 6 Pro
Ran Advanced System Optimizer
Ran CounterSypy
Ran Executive Software Diskeeper to defrag the drive
Ran a HiJackThis scan and upload the log to the HiJackThis Log Forum
Ran Spybot Search and Destroy
Ran System Cleaner
Ran Windows Registry Repair Pro
Ran a virus scan using Trend Micro PC-cillin 2005 Internet Security

Ran a multitude of virus and trojan scanners online including:

Panda Activescan
Trend Micro Housecall
and others that I can't even remember

If anyone has 'any' ideas please let me know.

Thanks!
