That was an old sig... Fixed... I just noticed that whenever I'm surfing in IE 11, my laptop fan comes on because my CPU is hitting like 70-90% and I assumed it was Malwarebytes fighting something trying to take over the browser...
Have Crap Cleaner and MalwareBytes Paid version... Still having issues with IE though...
In case of a badly infected system, you may want to consider using an AV scanner totally outside of the operating system.
Note: all of these linked items are free of cost.

Dr. Web LiveCD-LiveUSB 9.0.0 (03/11/2016)

Alternative: create a bootable USB 3.0 thumb drive (32 Gb or larger) as a "Windows to Go" operating system, onto which would also be installed several AV/anti-malware scanners.
Aomei Partition Assistant 6.0

This free software allows creation of the bootable Win-to-Go USB thumb drive.
This anti-spyware scanner is especially good for finding browser cookie spyware:

No but if you run CCleaner first it will delete a ton of files that your scanners won't have to scan which can save a lot of time. It's uninstaller can also be used to uninstall unwanted programs, toolbars, etc. Run CCleaner first before you run your scans.I just have to say this right now. Ccleaner IS NOT a virus cleaner. I don't know why so many people on the Internet think that.
