Hi there! I have noticed on the users folder that a new entry wangzhisong is present although no one has created this. I did a google search and this forum (particularly this topic came up). It seems my computer is infected and read the numerous step to clean. Can I follow the same thing or its a case to case basis? My computer has an active anti visur program (McAfee). I noticed as well as the firewall of my anti virus automatically turns off which indicates its compromise too. Help!
