Hello. This evening, I inserted a pen-drive that contained some games. Quick Heal(Full Licensed) has a habit of finding non-virus keygens as viruses. So I turned off it's protection. Then later on I realized that I was not able to open Quick Heal. I tried a lot but Quick Heal will open and within a second close. Same is the case with Task Manager. I then scanned my pc online from bit defender and found that the computer was infected by "Trojan.Agent.AOZO". I tried using temp window but to no avail. What do I do???
