[lonewolf999]

my friends computer got infected with the Internet Security 2010 virus and when i when to try to remove it the virus put the computer into a log in\off loop once i fixed that the desktop freezes and the virus has disabled task manager. the cursor is the I beam you cant click on any icons and you get an hourglass when you hover over the taskbar. but when left on for a bit my antivirus started updating so it dosnt look like a complete freeze
