Hi, BDani.
Although the general recommendation is only one real-time program monitoring your computer to prevent conflicts, there are many people who do prefer a second monitor. If you have a licensed version of either SAS or MBAM, see if you have any ill-effects with the real-time protection activated. However, I would strongly advise you not to have both real-time in addition to MSE.
Another option, my favorite, is WinPatrol. (You can read about a few of the features at
WinPatrol Features) WinPatrol is free for personal use and has a licensed version available as well.
