Gamepad on Windows

Thought I would reach out to see if there are any diehard gamers left after 4 months on steam. I have been using my PS3 controller on Windows 10 for years and it has stopped working. It now has 4 flashing red dots indicating it is not paired. The program that was used to install it is motion....... which is now a virus hotspot. Has anyone recently used a PS3 controller on a PC? If not I guess I will bite the bullet and buy a Xbox controller. Thanks, David
