Today Comodo Firewall stopped a rogue software trying to connect to the internet via AdAware update. Thanks Comodo, this is what I got the firewall for.
PS, the CPU usage did go very high during this, but this may have been more to do with the agression of the rogue software more than Comodo.
Anyway, ditched the rogue sw and cleaned registry and rebooted, goes good again now.
