Solve : Firewall Slowing Internet Connection?

1.	Solve : Firewall Slowing Internet Connection?
Answer» My ISP is Bell South (ATT). I recently up-graded my DSL connection to U-Verse, having been assured that this would improve my Internet download speed. It didn't; I was getting about 5Mbs before the change, and after it. (The speed was checked with ) Since my cost didn't increase, I stayed with the up-grade. Recently I have seen the speed decrease until it was only 2Mbs. My OS is Win2K, I am connected to the internet through a 2-wire router, which has a built-in firewall. My computer also had a firewall (ZoneAlarm) and an anti-virus program (Avast).I contacted U-Verse support about my problem, and, after the usual run-around, was told that the reason for the slow speed was a conflict between the router's firewall, and my installed programs. I disabled my programs, and the speed increased to about 10.5Mbs. I am concerned about no longer being able to use my anti-virus program. I can't get enough info from BellSouth about their program to quiet my fears. They say they no longer support Win2k, and ca't PROVIDE any info on what I can do. Does anyone have any suggestions as to what Anti-Virus program might work with the SETUP I have?I'd rather blame ZA, than Avast for your issue.

I have uninstalled each of them and re-installed them one at a time. ZA has a greater effect on the speed than does Avast, but both of them slow the speed down significantly.
