i think normal windows anti virus
you can turn it off only before the next reboot. More easier way is just to download other free antivirus (AVG is pretty nice)
Uhh it says there is somthing missing...
the best FREE antivirus could be AVAST Antivirus. best PAID one could be KASPERSKY Antivirus, yes.
I use norton, it that one like one of the worst?
