There are 2 things that I would try:
1. System restore to the point before you installed the software. Any personal files will not change.
2. Try 'Your Uninstaller' software. I used the trial version to get rid of a few intrusive programs like ZoneAlarm that would not uninstall or update. A Comodo customer rep truned me to this and a down computer is now working after more than a year of troubleshooting (

I hope this helps. Good luck.
