When using a VPN app, your primary assumption is that whatever the app is doing is done on a network that will keep your web browsing and personal data safe. But this may not always be the case when you’re not using the best mobile VPN. Research has raised concerns about the use of malicious VPN apps, largely due to the fact that Google Play has failed to warn against or restrict download access in its store. You can usually tell if your device has been affected by malware or adware when you notice significant changes in performance. If you don’t trust the VPN app or clearly understand what data they’re collecting and why, delete! Always check the VPN app reviews before downloading. In addition, run additional third-party malware scanners on top of what your device already provides.
