exporer.exe uses 99/100% of CPU System freezes

Whenever I try and open windows explorer it freezes, and the cpu usage become 100%. If I leave it running for a few minutes I eventually get an IRQL error (with no driver). Also if I try and browse (from the run dialog for example) then it freezes after a few seconds, as does the start menu.

Everything else works fine.
I can navigate through the dos prompt.

I am thinking that is a spyware/adware issue as this is what most people with the problem have reported (I've spent a good couple of days reading on the net).

I've tried disabling everything in taskmgr and it still doesn't work.

I have run antivirus, spybot, adaware, hijack this, cwshredder bho monitor - and can find no evidence of spyware...although as I mentioned before I suspect it IS some poorly written spyware.

Any help would be greatly appreciated because I REALLY cant figure this out, and rebuilding the system would be a huge pain.

There's a new forum for all this stuff... moved.

EDIT: I just realised that you posted this here too, so I deleted the other one.

I would fix these with hijackthis:

R0 - HKCU\Software\Microsoft\Internet Explorer\Main,Local Page =
O4 - HKLM\..\Run: [DigidesignMMERefresh] C:\Program

But other than that there is no malware present that can be seen with hijackthis and the entries I am having you fix will not affect CPU.
