Hi, I keep getting a pop-up message from a little red ball with a white cross in the middle - situated at the extreme right-hand side of the bottom of my screen, which says - Your computer is infected - Windows has detected spyware - It is recommended that you use special anti-spyware tools to prevent data loss - Windows will now download and install the most up-to-date anti-spyware for you. Click here to protect your computer from spyware! When I click on this icon, nothing gets downloaded or installed. I do have Windows Defender, which scans my PC on a daily basis, so I don't know what to do. I can't get rid of this icon either!!!!! HELP!!!!
