I've been looking for an antivirus app that doesn't run in the background all the time. I only want to use the scanning portion of the app, not have it monitor Android the whole time. My phone is small on RAM so I need all that I can get. I'm not a heavy web user and only access internet through apps, but I still need to keep the ads at bay. Is there such an app, or any options to turn off monitoring? I've already tried Norton and Lookout but they run in the background, and as far as I could tell there was no way to turn them off.
