Hi, I'm PhuGamer I'm using Wins 7 Ult x32 ( CPU E5200 Dual Core ) and using Bitdefender Internet Security 2012 UP-TO-DATE!! These days, when I try to open Pandora in Google Chrome or some software in my computer. One of my dual core is being up to 100% by the Vsserv.exe from BitDefender, I know that from Task Manager. Core 1 is usually normal, however, Core 2 is taken 100% by Vsserv.exe!!!!
