Downloading apps is very fun but where you downloading the apps from is not a fun thing.
We all use playstore even though there are many alternative app stores available, like fdroid but most of us do not use them because we do not know or we scared about virus or malware.
But how many of you know that google removes apps from it's playstore if it detects that those apps are vulnerable like virus or ads or in other way.
This only happens when google finds those apps, bit in the mean time so many of us downloaded and using the apps, when google makes announcement about these apps containing vulnerabilities those viruse or data collection or any other type of malware already infected to our smartphones.
Do not be scared by reading this, do some research and download from official stores or from any other trusted sources.
