Firewall, Avast, ZoneAlarm ?s

[pegg]

Finally - you all convinced me to bid farewell to McAfee and I took the leap. It did not go quietly I must say. I finally had to run RegCleaner and even now I have a file call McAfee.com that won't completely go away because it won't delet mcvsshl.dll which the file contains soooo

BUT my real question is:

I have Windows XP home edition on my Dell. I have the computer's firewall set. I just downloaded AVAST and have that all set up. I am going to reload Zone Alarm which gave me trouble in the past (I can't remember what now -- I had lot's of problems with this computer so I think I deleted several programs and have put a few back on one at a time).

Anyway, am I going to have any CONFLICTS with firewalls trying to block each other, the same things, being counterproductive???
