I don't know if this will fix the problems you're having, but let's get your system clean then fix the problems (if they still exist).
Reboot into Safe Mode
Open Windows Explorer, click on Tools, Folder Options, View, and select "Show hidden files and folders," and uncheck "Hide protected operating system files".
For every user account listed under C:\Documents and Settings, delete the entire contents of these folders:
Cookies
History
Local Settings\Temp
Local Settings\Temporary Internet Files\Content.IE5
Delete the entire content of
C:\Windows\Temp folder
C:\Temp folder
Do a search for *.tmp and delete everything found (hopefully your search function will work in Safe Mode)
Empty your Recycle Bin
Scan with HJT, and have it fix the following entries:
O2 - BHO: CATLEvents Object - {2527BEEF-1B3C-4D3B-98F0-7F3C1EB910A0} - C:\DOCUME~1\JULIAN~1\LOCALS~1\Temp\avajxaf.dat
O4 - HKLM\..\Run: [*faxjava] C:\WINDOWS\Tasks\faxjava.exe
O4 - HKLM\..\RunOnce: [*faxjava] C:\WINDOWS\Tasks\faxjava.exe rerun
Close all windows, other then HJT, before hitting the Fix button
Go to C:\WINDOWS\Tasks and delete faxjava.exe
Reboot normally
Go to Windows Update for updates (this may fix your WMP)
Close all browser windows, scan with HJT, and post a new log please.
