The only way to get rid of them in the Free version is to select Silent/Gaming Mode in General Settings.
The problem with that is you will not get important alerts about malware or virus infections/attempts.
2. By all accounts this isn't totally correct virus alerts would take precedence over silent mode.
However there are some interactive windows such as, if you have hardened mode (Aggressive) enabled you don't see the interactive window when you launch a program. The program just won't launch, that is essentially your only indication there is something going on under silent mode.
At that point disable silent mode and launch the program and you should see the Hardened Mode interactive window.
