The McAfee antivirus that I am using has alerted me that Trojan.Fakeav-42 has infected the system. I am using Windows Vista operating system and my browser is Opera 10. The problem is that even if the antivirus has detected this infection, I cannot remove it from the antivirus interface. Nothing happens when I try to delete this infection from my system. I am getting irritated by the alerts of this infections. Hence, please provide the solutions to remove the same.
