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.
No, it's not a virus. The notification is triggered by advertisements on the webpage.
Just don't click "OK" and ignore it.
In this particular case I guess it is a case of an advertiser lying to you in order to convince you to buy a product which you don't need.
It seems to be an App which opens that dialog (over a webpage...).
Try to boot into safe mode:
Press and hold the power button until the power menu appears.
Hold down 'Reboot'. (On phones which do not have the option to reboot press and hold 'Power off')
Then your phone will reboot into safe mode. That means all your apps are deactivated for this session. IF you won't get any of these weird dialogs there THEN restart your phone (to get all your apps back) and deactivate/uninstall your apps step by step.
You can also try AdAway, which has an inbuilt AdWare Scanner. (https://f-droid.org/repo/org.adaway_51.apk)
Not a virus, but a simply advertising popup which leads at website to avoid. Block the url from your browser!
Screenshot Pro displays these annoying, persistent ads with "smart application management" notifications. If that's not it then look for other apps that you recently installed or updated in Google Play with WiFi access. Disable notifications on the suspected app to see if it is the source of the ads, then uninstall it if disabling removes the ads. I had to disable it as a device administrator to uninstall screenshot pro.
