Am I over protected, to the point of possible detection issues due to conflicts? Firstly, realize that I built this x64 machine in 2012, so it's not like I just purchased all of this. Secondly, not that I could not be duped, but there is a much greater chance that my wife could. Thirdly, with a SSD and an Ivy Bridge Core i5 3570K 3.4GHz CPU and ample RAM, there is no noticeable performance hiccups either. The only recent purchase was WinAntiRansom in December, as I fell pray to the ransomware paranoia. I also updated Malwarebytes Premium to v3 today without a hitch. The list follows in alphabetical order and all but Norton are lifetime licenses. Malwarebytes (Premium), Norton Security, Sandboxie (I reasonably know how to effectively use it after all of these years!) and WinAntiRansom. Thank you!
I don't think you can have a detection issue Sandboxie is a different creature, MBAM and Norton are supposed to be compatible. The only thing that could be overkill is that you have 2 antiransomware products MBAM antiransomware module and WAR but they should be compatible or at least I have never seen anyone complaing about incompatibilities.
