Uggh get rid of StyleXP - it's loaded with spyware, keyloggers and adware...
Another way to clear some of those nasty things is to:
Open Start Menu and Select 'Run'
Type: msconfig
Press Enter key
click on startup tab (end tab)
deselect everything from the list (except stuff you're sure is safe - ctfmon.exe always reloads itself so there's no need to disable that, and msnmsngr.exe will probably reload itself upon startup).
Apply and restart the machine
