When I follow link from either QR code or email and go to Norton to install antivirus software, it says software is not compatible. Tablet is running android 11 so should be fine.
Solved! Go to Solution.
Seems that Samsung Galaxy tab a has McAfee pre installed, though there is no McAfee icon. That seems to be reason it won't install.
Thanks for your time.
The McAfee App may be pre installed but it shouldn't be activated unless you have set it up.
If it is not activated just fined the app and uninstall it.
