I am no expert but willing to learn. U have had my homepage hijacked by whatsfind.com which disabled task manger, home page options and many other run commands. I have done the following: 1- restart in safe mode. 2- open my computer. 3- drill down to program files. 4- delete windows update file. 5- delete keygen.exe under windows update. 6- empty recycle bin. 7- shut down and restart. This have helped me to start my Internet Explorer whitout any problems so far. I hope it would help someone.
