"Bricking" is the process of turning a physical piece of hardware into a device as useful as a "brick" (thus its name). It was coined to describe what happens when you try and flash a phone and it is unrecoverably damaged.
Even if you remove key Windows files sometimes Windows can recover its self using the backup copies located in %windir%\winsxs\Backup (and several other places depending on system configuration).
But generally bricking refers to the state of disrepair where something has to be thrown in the bin because it cannot be used in the future. The closest PC equivalents would be either corrupting the BIOS/UEFI or over-heating a component like the graphics card.
It's difficult to brick a phone these days.
1. The software becomes sentient, learns to define, recognize and delete viruses on it's own.
2. The software realizes that by every definition it is itself a virus and must delete itself. :)

Recent movement (last couple of years) by AV companies blocking everything which leads legitimate small businesses to take the stupid whitelisting route via AV companies or pointless customer calls to explain it's a false positive (and even when customer is convinced it's still not good enough because corporate doesn't allow them to exclude some binaries or disable AV).
1) Why don't they have a secure hash of each of the files and add that to a whitelist of files never to delete?
2) "You want to ensure your secondary option (when cleanup is not available or does not work) to be set to 'deny access' and not delete or move." Is this not the default configuration?
