After an update to ZoneAlarm personal firewall caused my PC to hang, I uninstalled it via Add/Remove programs and then followed the instructions from their support website about manually uninstalling files that remain.
I've now installed Comodo firewall but Windows Security Centre fails to recognise it and also shows that "ZoneAlarm reports that it is turned off".
Despite running a Registry Cleaner it still appears in Sec. Centre and my internet connection is almost non-existent unless I use the Windows firewall.
Any thoughts would be appreciated, as I'm scratching my head on this one....!
