I have a Dell XPS 15 9560 and it is running very slowly. When I use lightroom, it often crashed. Can you offer a solution pls.

Thanks rproffitt,
I have followed the instructions from your link above by scanning with all the tools suggested, but I still have PUP popping up each time I click on Chrome. It's clear of any threat by SuperAntiSpyware and HitmanPro but Malwarebytes Anti-Malware still show the following 6 PUPs:
PUP.Optional.PricePeep
PUP.Optional.PricePeep
PUP.Optional.ReMarkIt.PrxySvrRST
PUP.Optional.ReMarkIt.PrxySvrRST
PUP.Optional.Yontoo
PUP.Optional.Yontoo

What else must I do to rid all the threats?

Thanks,
JK
