99.9% of the time, viruses don't just attack you out of nowhere - rather, the user is to blame
Even on Windows, an anti-virus is unnecessary if you know what you're doing. Don't click the wrong 'download' button; check file extensions, etc. Trust no one and trust nothing before doing your research. With the right mindset you can avoid mallard and viruses without a third party scanning through your files and information
AVG is bloated, Norton is basically a death sentence for your PC. Kaspersky = Russian intelligence
A lady from work had me fix her tablet yesterday - it had the FBI lock on it, LOL. How did she even install it? Her son who 'went to school for IT' couldn't even boot it into safe mode & Uninstaller the app (literally named malware.apk)
Stuff blows my mind.
