Battery Consumption

A couple of days ago, "Webroot Secure Anywhere" began chewing up the battery on my Android phone. I depleted my 100% charge down to almost nothing in a couple of hours and my my phone got hot. I look at my battery log and it says that it is that app that is causing it. I uninstalled the app and the battery consumption resumed a normal pattern. After an hour or so I reinstalled the app. For the next hour and a half it was fine, then kicked back in sucking my battery dry. My phone is only a couple of months old. Has anybody else experienced this? Is there a solution??
