After free 2011 AVG install with Clamwin still in machine. icons have disappered off desktop and no connection + message this computer has been locked only owner can unlock. start menu says owner so ?? HELP this is for my Lady friend who needs computer for biz.
I don't know what Clamwin does, but AVG 2011 (ver10) has different security than 9, you need to grant Clamwin any and all permissions on AVG to allow it to run normally. I had to setup secure e-mail account by account on this new AVG.
Second thought, try loggin in as Administrator.
