The best part is it's free! It comes with all of my programs which makes things easier for me as I'm not constantly having different antivirus software installed everywhere (which could lead into problems).
There are some bugs here or there but nothing too major just like any other program out their - no big deal really though since they're easily fixed through updates if needed/wanted by you guys at Microsoft directly instead than waiting months until someone else fixes them themselves haha :D Overall great product so far!! Definitely recommend getting this one when looking around because once again its 100% FREE. Nothing much about exchange defender itself yet only minor stuff such us pop up ads every now & then etc.. But overall good enough considering how cheap we paid compared to others who charge more money per year subscription fee wise hahaha.
