This is getting more an more strange, it's svchost.exe that causes the problem and it's running cryptsvc, dnscach, ktmrm, nlasvc, tapisrv and TermService looking at the thread it's either crytsvc or ntdll that are using the CPU.
However there seems to be a problem with windows update in that I tried to update avg to version 8 and it refuses as it needs KB929547 I downloaded that and it starts to install then just stops, this is despite auto-update loading all current patches. Some other installs will not work either.
I've included a Hijack this listing:

If you have an incomplete avi file, or a damaged avi file, explorer will read it frame by frame to determine it's properties (such as video size, length etc..)
You can confirm this by starting the task manager next time it happens, I know it will takes ages to open but be patient! if you see that explorer.exe is the process using all your CPU do the following:
1. Open up regedit
2. Goto HKEY_CLASSES_ROOT\SystemFileAssociations\.avi\shellex\PropertyHandler
3. Delete the "Default" value which should be "{87D62D94-71B3-4b9a-9489-5FE6850DC73E}"
After restarting the problem should be solved. **note** You won't have any video properties any more if you right-click and avi file, but I'm sure you never use it!
If the process is not explorer.exe then there are a few other problems that could cause the same symptoms. Some people suggest that the print spooler of all things was the cause!
You could also have a keyboard issue, some logitech keyboards have some driver issues which can cause the 100% cpu usage. Also physical damage could case the problem (which could mean continuous interrupt requests and hence 100% CPU utilisation)
