Seriously, I kept wondering why such kept happening that way because under a normal circumstances, I believe the anti virus was even supposed to help the game play well.
Haha, I actually felt like that in my playing of PVP in Frontline Commando and it was so annoying because I really felt like I was good till I got my ass handed to me.
Seriously, I never really took it seriously till it got one of my PS console messed up pretty bad that I had to go for full maintenance before it was able to start playing again.
No matter how much people disagree with that, it doesn't change the fact that we always assimilate most of what happens around us and it takes a hold on us with gaming behavior.
