A bug... i think...

Ok… so i got comodo EasyVPN and set it up yea yea, everything working fine. Then, while we were playing a game of Star Wars: Jedi Knights 2(me and my buddy), it started having enormous lag! the pings shot up to 999ms from 50ms. Confusion? So anyways, it’s been happening all the time in every game where when we play it will be fine and then after a little while it would just freeze and then it would go back to normal… getting "connection interrupted"s all the ■■■■ time.

There is no net usage apart from Comodo at any time during the games and i dunno what to do.
