Internet Defender is a fake anti-virus scanning tool made to look like a legitimate Windows program. Once installed to a computer Internet Defender will configure itself to start automatically when Windows starts up. Once the program runs it will begin to do numerous scans that come up with virus entries that it found on your computer. These warnings and scans are problems it finds are not actual threats but made up ones the program creates. If you attempt to remove the issues with Internet Defender it will ask that you pay for the full version. You should never purchase this program, Internet Defender was created to trick users into purchasing a fake program in an attempt to steal credit card information.
Manual Removal: Internet Defender will configure itself to disable some Windows Utilities so in order to remove it you will need to restart the computer in safe mode. To do this first shutdown the computer, during the next start up tap the F8 button until you are given a black screen with the advance start up options. Once at this screen choose Safe Mode or Safe Mode with networking. If you do not get the advance start up opition when pressing F8 it most likely is due to incorrect timing of the button press. Once in safe mode find the files listed below and remove them.
