malware - Is this notification that keeps coming up on my phone a virus?

This notification keeps coming up, and i'm not sure if it's real or a virus, or how to stop it coming up. It says 'Android system warning! Google has found serious bugs in your Battery Module!Click on [OK] to view details.'

Any help appreciated, thanks. Lauren.

Answer

No, it's not a virus. The notification is triggered by advertisements on the webpage.

Just don't click "OK" and ignore it.
