I had major problems with Comodo. And it was the devil to remove. It left a lot of residual stuff that I had to weed out.
FWIW, I had problem’s connecting this a.m. as well, having installed Zone Alarm a few days ago, and having Windows XP updates over the past few days. I found that my Internet Security was set to HIGH in Zone Alarm. I reset it to MEDIUM and the problems went away.
Of course, this was after about an hour of fooling around with my modem & router.
Thanks for the info, I had periodic problems with ZoneAlarm in the past and if I recall I did the same as you and lowered security level to get things to work properly with certain applications. I am not too tech savvy but it seems as though ZoneAlarm was a bit more user friendly for newbies than Comodo. Maybe I’ll switch back(heh, if I can).
