I suddenly notice my ping is at --- about few months ago. Port Forward won't work cuz teh login is rigged. Besides port forwarding is no longer needed. Dedicated don't work also. I believe it started happening ever since my dad got this Kaspersky Internet Security installed on my computer. What do I do? Do I shut down whole firewall on it?
What do you mean by "rigged"?
You will need to either have port forwarding enabled or UPnP, the only way to do that is by logging into your router (most routers don't have these enabled by default).
If you are 100% sure it is your firewall, as Treynolds said, just set up what is usually known as an "Exception" or "Allow Rule" in your firewall, I am not familiar with Kapersky, but I suspect it has similar features.
