No, it's a complete waste. Android is a sandboxed OS, meaning that it is very unlikely to contract an actual virus. It's more important to read reviews, 1 and 2 star reviews in particular. Often these reviews will tell you if the app has annoying push notifications or pop-up ads. Check permissions. Too many permissions can lead to malicious activities and behavior long before a virus will ever invade your device. Don't be the first. Don't jump on new apps if there's less than 50k downloads you're probably better off finding another app. My rule is 100k. Don't install anything with less than 3.5 stars. Again you're probably better off finding another app. Don't install anything with as many 1 star reviews as 5 star reviews. 5 star reviews can offset the 1 star reviews and make apps look better than they are and reviews are easy to fake, and which rating do you think fake reviews will give? Stick to name brand apps, if you haven't heard of it there's probably reason. Be informed, be proactive and worry less about what might get in and more about what you let in. Gl
