I did add this to another thread but reakised too late that the thread had been marked as resolved so here it is. Can't install firewall Hi guys, some time ago I uninstalled PC-cillin 2003 which included a firewall because it had come to the end of licence, I installed AVG without problems, but just lately I tried to install "Zonealarm" but my PC informed me that I already had a firewall installedon my PC, the PC-cillin one was the only one I have ever had installed. There must still be some evidence of that firewall somewhere on my PC. Does anyone have any ideas on getting rid of it so that I can install one that works? Thanks, Boon.
