Antivirus problem

[dialysis1]

Everything was fine until last night. I updated my AVG antivirus program. Then I no longer had internet access of any kind. I would disable AVG and my internet was back. I uninstalled the program and reinstalled. Same problem. I uninstalled AVG and installed Avast. Same problem. Firewall disabled. The only way I can have internet is to shut down the antivirus program. I've done a system restore and cleaned the registry with CCleaner.
Any ideas?

How are you connected...dialup, DSL, or cable?

I fixed the problem.
I have disabled ZoneAlarm firewall weeks ago from my startup. There was nothing I could find that showed anything relating to ZoneAlarm running yet I just noticed that it was still creating .tmp files in my Windows/Temp folder. They were dated today. I completely uninstalled ZoneAlarm and reinstalled AVG. Everything is fine. Go figure.
Thanks anyway.
