Hello, I have a PUB called BuyNSave on my chrome internet extensions that refuses to go away. I ran Malwarebytes, Malwarebytes Rootkiller BETA (MBAR), Roguekiller64, Rkill, Adwcleaner, Spybot Search & Destroy, TDSSKiller, Combofix, JRT, TFC, and Farbar. I've ran scans that deleted some stuff, restarted computer, then found nothing to remove yet the BuyNSave extension was still enabled in my Chrome extensions. Then I uninstalled Chrome and reinstalled it, which now I have the option to disable developer mode extensions. So now the BuyNSave extension is still in Chrome, but not enabled. I'm not exactly sure what to do now. But if these are still major threats I'd like to know how to get rid of it if there's anyone that can help me. Thank you.
