In all honesty if you have MBAM then SAS is a bit surplus to requirement, its scans are mostly going to be showing tracking cookies, which really aren’t an issue and one which MBAM and avast doesn’t bother looking for.

You should set your browser/s not to accept third party cookies, these are commonly the ones considered as tracking cookies. If you use firefox you can also use CookieMonster to manage cookies and you can also set your browser to clear browsing history, temp files and cookies when you close the browser.
