Me too. I use Windows Security Essentials and Malwarebytes, very compatable and no interference (slow down) with other programs even when editing HD video. Norton sucks. A computer programmer once told me that Norton gets into everything and your computer slows way down.
What does Malwarebytes add that Windows Security Essentials doesn’t have?
Heh, I just posted (#39) and then scrolled the earlier replies and noticed you have the same setup as I have. I’ve had zero problems, and I agree that the two programs are very compatible and there is no computer slowdown with both going at once.
