The Firefox browser window is not displayed the first time after the computer has been started up and running Windows XP Professional Version 2002 SP3. In Task Manager the firefox.exe is running. When the firefox.exe process is ended and restarted, it will take a very long time to display the browser window. When I looked at the task manager again I noticed that wmiprvse was running at about 25%. When I end both the wmiprvse and firefox processes, the wmiprvse process restarts with 0 to 1% and the firefox browser is displayed in a reasonable time.
During browsing, a tab is randomly opened and a random webpage is displayed. These webpages can be removed.
Over the past couple of weeks I have run full scans of my boot drive with the latest versions of the following applications:
Each time, hi-risk trojans have been found and deleted/quarantined. A few occasions I have run regedit to remove bad entries in the HKEY_LOCAL_MACHINE\SOFTWARE|Microsoft\WindowsNT\CurrentVersion\Winlogon\Userinit or Shell registries. e.g. rundll32.exe, twex.exe, sdra64.exe and cdav.ixo ukqudnn. I used the 60 second timer method for removing the bad entry.
Today it is "msjiyf32.exe" in the Userinit registry.
What shall I do next?
