    Thanks for doing this. I just want basic malware protection and malicious website scanning; almost all these guys pack in stuff I don’t want that bloats the package and uses a ton of memory in the background. Case in point, I had been using CM Security Lite (in combination with Web of Trust) but tried Malwarebytes. Memory use went up and Malwarebytes is using more battery than any other app. My phone has 3GB of RAM, and average memory use went from 66% to 89%. No thank you. Anyway, CM Security Lite is apparently not compatible with Android 9 (I was getting “this app was designed for an earlier version of Android” prior to switching). I emailed Cheetah regarding the CM Security Lite app but did not hear back. I guess my only option is to try Dr Web Lite. If you find any other security apps that use less memory feel free to let me know.
