A few weeks ago I updated my Comodo firewall to the latest version (4 i think?) after getting pop ups from my Comodo firewall icon. I had a bit of a job installing it, had to try a few different times.
Since then I've been unable to turn off my PC the normal way as 'Comodo firewall is not responding'
I tried turning off the firewall manually before turning off my pc the next time and this worked ok.
Ever since then i've been unable to even open the firewall by clicking on either the main desktop icon or the one in my toolbar, which says its running.
Is it possible i've installed a rogue Comodo firewall?
If so can you recommend a better free firewall?
i'm still using Windows XP and firefox ,by the way
