I really need help with my computer, I dont know much about computers so may need quite a bit of detail. Recently my windows defender has been showing I have a virus called Backdoor:Win32/IRCbot.gen!W iv tried downloading avg and avast and have also tried my norton but each time I try to set up these anti virus softwares it comes up with a system error so I cant open any of them. iv added a picture to this post,,, this is the message I get whenever I try to open my anti virus softwear, it happens on everyone iv tried.
