Download, install, update, and immunize your System with it.

Important re: Safe Mode
If you happen to find a problem that you canâ€™t uninstall / delete, reboot
the computer, and go into Safe Mode.
To get into Safe mode, tap F8 right at Power On / Startup, and use UP arrow
key to get to Safe Mode from list of options, then hit ENTER.
RESCAN your computer with Anti-virus and Spybot S & D while in Safe Mode
