When i start my windows, a "blank" IE page starts automatically...i dont have anything in my startup programs,,,,ive done "msconfig",,,and de-selected some things,,,ive run an AVG anti virus program which doesnt find anything,,,ive defragged, but this stupid window pops up everytime,,,,Do i have an unknown virus,,,do i need to go buy a new anti virus program,,,any suggestions would be greatly appreciated
