I have some questions connected to Windows Defender. It would be great if someone would tell me a bit more about how it protects system and the whole pc. As I do a lot of research and receive lot of documents, I want to know how Defender works.

1. Does Defender protects pc and blocks sites or files which might contain virus before they are opened or downloaded (here I mean mainly Documents)? I guess that Edge uses this option (Smart Scanning or so), but does it work on other browsers? I know that some other antiviruses had such options like that. I wanted to know if Defender has it as well?
2. Does Defender deletes viruses in100%? And does one fresh reinstall system or one formatting makes viruses disappear for 100%? And what's difference in case of safety from viruses for any storage - fast vs slow (full) formatting? By the way, isn't there in reinstalling system only the 'fast formatting partition' option?
3. Are there any options worth turning on to make pc even more safe? Especially when people work and have to do a lot of research or get from others document files.
4. What is the option "Random Device Mac Address" and does it have any impact on safety of devices? If it doesn't, why is this option there, as well as for phones as I've seen? Is it like preventing virus to block device through mac address?
5. Is it safe to plug USB Key with Windows reinstallation (made through official Media Creation Tool) to the pc in order to reinstall the system, while there was a virus on the pc? Wouldn't the virus get into this USB Key, making it reinstall system with virus?

I know that some other antiviruses are quickly blocking sites or files which might contain virus before it get to the pc (For example Malwarebytes). That's why I'm wondering if Defender offers the same way protections?
