If you haven’t already got this software (freeware), download, install, update and run it periodically.
Don’t worry about reported tracking cookies they are a minor issue and not one of security, allow SAS to deal with them though. - See http://en.wikipedia.org/wiki/HTTP_cookie.
You can add either or both of these as on-demand scanners or if you wish purchase a one time life-time license for MBAM Pro or SAS Pro, but not both as essentially these anti-spy/malware applications follow the same guideline of only one resident anti-spy/malware application.
If you elect to have a Pro version of one of them it shouldn’t conflict with avast.
