In this article on Poynter, Ren LaForme gives some advice on how to avoid downloading apps which may slow down your phone or try to steal your personal information.
Trying to trick as many users as possible, some of these fake apps resemble more popular ones in terms of designs and names.
To detect untrustworthy apps, always check their description for any misspellings and make sure the developer is reliable and has a professional website.
Also, don't forget to check the reviews, as high ratings are no guarantee that the app is safe. If the comments are written in a bad language with lots of spelling and grammar mistakes, this might be a sign that the app is probably no good.
If you still notice anything odd on your phone after removing the problematic apps, LaForme recommends “considering a factory reset or a visit to the store”.
