Invalid License ???

Recently installed COMODO Firewall Pro version: Firewall status is not functioning. Run Diagnositics wont work and the thing is just stuck. Have tried to uninstall it just keeps coming up with errors. Have also tried to install a fresh copy, but that wont work.

Help…please ???

You need to do a complete uninstall. I use Revo Uninstaller in Advanced mode. When Comodo says reboot, dont and click next on Revo and delete the left over registry and program entries it finds then reboot. Use CCleaner registry cleaner and reboot. Install Comodo. Are you using any other security products?

Im using AVG Anti Virus and Spyware Terminator. I will try to uninstall…many thanks.

Spyware Terminator is not needed and is bloated junk. Spyware Terminator also has HIPS so you cannot run 2 HIPS at the same time.
