Hi Neil. Thanks for the link to the Comodo firewall. I installed it tonight. After installation, when it asked me to reboot, I got an error message that my operating system was missing. Yikes! However, when I cold started the machine, Windows loaded in normally, well sort of anyway, as I was asked by Comodo to approve a lot of M$ system programs. I guess I'm spoiled by Zone Alarm which recognizes almost all of those programs and pre-approves them. Nonetheless, it seems to be working well and a scan I did with it found 3 malware programs that AVG apparently didn't. I do feel better with it running rather than the Windows Firewall. So thanks again.
Gerry
