anyone knows here how to ignore someone want to block my computer?

first thing you should do is unplug your Internet connection....Obviously, the guy is trying to attack your PC via the Internet Secondly, make sure your anti-virus is updated....do a thorough scan.....if there's no virus, try another anti-virus program if you have to And if all else fail, backup your data and prepare to format your hard disk....a clean hard disk will be cleared of all viruses and such (mostly)....
