I was searching up fun computer games to play when a message came up saying I have a virus and I should download this weird app and give it a lot of my personal information including phone number and email.
I'm scared this is a scam. What do I do??
Congrats! You won 10 bottles of snake oil if you're lucky.
Honestly: this has two very clear indicators of being scam:
Ignore that message (close the tab of your browser were it appeared), but remember that website – to never visit it again.
If you're referring to the the pop-up with the (fake) countdown timer on it, which I've seen before, then just know that it doesn't have malware, and neither do any other pop-ups. They're just pieces of scareware (Advertisements designed to scare the victims into a reaction, like downloading an app). If it'll make you feel better, then feel free to download a (legit) anti-malware app on the Play Store and perform a scan with that. My personal recommendation is Malwarebyte's Android app: https://play.google.com/store/apps/details?id=org.malwarebytes.antimalware&hl=en .
