Adblock plus isn’t a security program, and it doesn’t clash, it just blocks some ads.
The clash problem is running more than one anti-virus, or more than on firewall.
Your superantispyware and malwarebytes won’t clash either, because for one thing, you are using the free versions, which only come on when you manually update them and do a manual scan, they don’t run on their own, unless paid for.
Open your malwarebytes, and click on scan, it will automatically update, and then do a quick scan, when your computer is going to be on for a couple of hours do a deeper scan by clicking on the scan button and click on “custom” scan, then the “configure” button, and check everything, including “rootkit”, then start the scan.
That deep scan is much slower, but you can use your computer while it scans, and it really digs into the system.
So, did anything come up up when you did your Malwarebytes rootkit scan?
