Recently I see that my computer is slowing down and lagging when I browse websites and opening programs. So I thought a reboot will solve this problem. But as soon as mysystem starts, it begin to run slow and lagging again. This continues until today when I disabled the resident shield of AVG and my system run smoothly again. I have been using AVG together with NAV for a long time without any problem until recently. So I guess I have to uninstall AVG soon. Anyone here can recommend any antivirus that can work well with NAV?
