My computer is attacked by HORSE AGENT.YZB virus, MSE gives me the virus warning when I try to install a free program downloaded from forum, however, each time when I try to get rid of this Trojan horse by security tools, I’m told that this virus can be only removed manually but I have no idea how to do that. What is my way to remove this threat from my computer completely? Is there a guide which I can follow to save my computer? Any help will be appreciated.
