Detecting and preventing viruses on the android OS
Here’s the bad news. As a programmer, there is more money in taking the Android operating system apart and exploiting it than there is in helping people prevent and detect viruses/malware.
Why such a bleak outlook?
Go to Google Play and you will find a chunk of virus/malware detectors for free. People aren’t spending big money on protecting themselves, so companies are not investing big money in protecting people (it’s called economics).
How to tell if you have a virus/malware?
You are reading this, so you have. You are reading this because your device goes slower, it freezes, or it acts abnormally: maybe you keep getting charged for something;, maybe you cannot sign into a website that they should be able to sign into; or maybe you cannot figure out why you are getting more spam calls, texts, emails or social media posts.
Guess what? All of those are symptoms that your Android has been infected, and the worst part is that there is little chance your virus/malware checker will pick it up. It could be anything from a system infection or bad cookie, to a backdoor in one of your apps.
You have two options
Try as many virus/malware checkers as you can until you find the problem, or re-format your device and start from scratch. The worst part is that most free virus/malware checkers will show false positives to make you glad you downloaded the checker. They can then market their paid services to you more effectively because you mistakenly believe the software works.
The situation has become so dire because the Android is the most widely used “mobile” operating system, but unlike with Windows there is no financial advantage to helping people protect themselves because companies simply cannot make enough money to afford large programming teams.
