MOVE HJT to its OWN directory, not in Desktop or Temp!
C:\Documents and Settings\Administrator.JHU-ME6KOJ489K6\Local Settings\Temp\HijackThis.exe
Boot in Safe Mode.
Press Ctrl/Alt/Del simultaneously, select Taskmanager/Processes, select the process (if there), click "End Process" for:
kapuhl.exe
Next, run a HJT scan and place a tick-mark in the little square before (if still there):
...................................................................................................
C:\WINNT\system32\kapuhl.exe
O4 - HKLM\..\Run: [KavSvc] C:\WINNT\system32\kapuhl.exe reg_run
O4 - HKLM\..\Run: [AUNPS2] RUNDLL32 AUNPS2.DLL,_Run@16
...................................................................................................
Now click on the Fix Checked button in HJT.
When done, from between the dotted lines, delete the highlighted bold files.
Delete all files and directories from: C:\Documents and Settings\[username]\Local Settings\Temp
Repeat this for ALL [usernames].
Delete all files and directories from: C:\WINDOWS\Temp (except files dated from TODAY).
Boot normal.
