• Answer:

  hi, perhaps you can try Norton to remove the virus. but you need to pay for the software. i recommand you to use firefox with Google toolbar. firefox can disable all virus to run, because the virus can only run on IE. besides, firefox can block any any poppus and disable any virus and adware, spyware on webpage, so, firefox is much safer than IE. as you know, most of the virus is spread throught internet and webpage. firefox is much smaller than IE, so i run faster than IE. download firefox for free: http://www.bernanke.cn/firefox/ Best Wishes && Good Luck!
