I received a notice from Bitdefender that a file on my computer is infected with Trojan.Groooboor.Gen.22 and was moved to quarantine. This file is 5 years old. Why am I just now getting a notice that it's infected? Is it possible that the file really isn't infected? Also, within the same time frame, I received a notice that my firewall was enabled. Does Bitdefender turn firewalls on and off? If so, why does it do that?
