Hello my dad has the s10+ and his screen flashes blue and notifications keep popping up about virus and stuff like that any help/advice would be appreciated.

There is an inbuilt virus scanner in your Device Care @zoeaustin 

Other options are available in the PlayStore too. 

You can also try Clear Cache Files from the phone's System Partition Section  > https://www.samsung.com/uk/support/mobile-devices/how-do-i-clear-the-cache-on-my-device/ You may need to insert your earphones or hook upto a powered On Laptop or use a Tv's USB Port or a usb-c to usb-c phone to phone set up to access the Clear Partition Section. This may help with lag or stutters as this clears the phone of old/unused or broken cache files.There is also a Repair Apps option in the Menu System too { Possibly excluding the s²⁴ Series of phone's }

We just disabled google Chrome for now that seemed to work also removed some permissions as well
