Hi there. I have a stubborn virus on my computer that I cannot get rid of it. It is called Backdoor.ExtenBro.AK. My antivirus keeps telling me my system is infected but it doesn’t seem to cure it. I clicked ‘Remove’ option a few times but when I restarted it, the virus came back again. I opened task manager and found some strange processes taking up a large amount of memories. What should I do? Is there any other way I can remove the virus completely?
