!avast Or My Old Router Causing Game Lag?

[Krocket]

Maybe 2 months ago I started getting choke in every Valve game I play. Not sure if I get it in any other games because a 'choke' value is not displayed but they seem to be okay. Anytime a server has a lot of entities/players I get VERY laggy. On servers with 24+ players my choke can go from 50-100 which is not even close to playable. Is !avast behind it or something else? Fresh installs of the games and making sure my system is completely clean of any virus didn't help. It's on any server as long as it's a busy one as well.

BTW I've never been able to connect to local servers my friends host. Doesn't matter if it's from their computer or some provider like hamachi, doesn't work. This leads me to think my problems might be from !avast and something to do with my ip.

if you right click avast tray icon and pause shields for 10min .... is problem gone then?

Guess that answers that question. Still laggy.

My internet seems flawless so I find it difficult to believe it could be my router, especially since I got back 0% packet loss on that test. Kinda lost on what to do. I'll look for programs running in the background that might be causing it.

You may want to check with your ISP and/or Valve. Lag is usually ISP's fault.
