Why does it keep happening to me???

its well known that avg thinks maple is a virus due to the encryption they use to protect the wz files. the only ways i know of to prevent all this pain is to either go into avg's ignore list and add your maplestory files and go to the virus vault to restore the ones it "deleted" or change to a different virus scanner/firewall.

personally i'd go with microsoft security essentials, its free and doesn't cause the mini lag spikes i get with avg
