- Almost Every Anti-Virus App
What it is:
There are loads to choose from; most of the well-known desktop anti-viruses now have a smartphone offering.
Why it’s bad:
They aren’t bad per se, but they are largely unnecessary – that’s why the biggest names in the industry now market their apps’ anti-virus capabilities as part of a larger security package. There are a couple of caveats, however; if you install software from third-party sources(i.e., not the Google Play Store), or if you have a rooted device. Both these situations can open you up to malware that Google has no control over.
What you should use instead:
In this case, it’s not so much what you should install instead, but rather that you need to make sure you’re installing a full-fledged security package from a recognized provider. The apps from companies like Avast and Avira tend to offer additional features such as password-locked apps, remote device wiping, and call blockers.
