It's causes problems with Windows update after every 2-3 months. It's real world detection rate is lower than Bitdefender/Kaspersky/Avira. Only best thing it has now is bells and whistles.
I've spent some times in an south Asian AV shop. Here general people most often make bad choices when buying an AV, their choice heavily depend of friend's suggestion(who is not probably tech savvy) and on "Visual Looks, bells and whistles". Many people here use Indian made Quick Heal seeing TV ads whose detection rate is actually worse than Windows Defender itself. In other words, your PC is comparativly safer without an "Antivirus" than installing one like this.
