Bad installer

This messed up some stuff on my windows 7 install like uninstalling Firefox for me O.o

  1. download and open the installer
  2. keep pressing next till you get to the configuration wizard oh great theres no cancel button once you get here.
  3. press next until you get to the selecting components part e.g. firewall, antivirus
  4. press alt+f4
  5. restart the computer when asked the firewall and antivirus still decide to install them selves but mess up
  6. wait till comodo tries to installyze its self
  7. run the diagnostics wizard
  8. restart when asked this is when Firefox stooped working

Sorry Firefox doesn’t get uninstalled it just stops working even when I install Comodo correctly but it works OK once I reinstall it after downloading it from internet explorer.
