Windows Defender and Herd Immunity

Types of computers, protected with antivirus software:

  1. Fully Protected Machine
  2. Partially Protected Machine (detection patterns are not kept updated)
  3. No Protection, with Common Sense
  4. No Protection, no Common Sense

Scenario 1: Everyone has #1 computers. Herd Immunity working at full protection.
Result: The spread of viruses, trojans, and malware are virtually nonexistent.

Scenario 2: Most everyone has #2 computers. Herd Immunity works, but there are certain rare vectors of attacks that are vulnerable.
Result: viruses, trojans, and malware are sporadically spread through unprotected computers, causing havoc but damage is minimal.

Scenario 3: Everyone has #3 computers. Herd Immunity is not enabled as there are too many unprotected vectors.
Result: viruses, trojans, and malware spread throughout connected networks undetected (as there are no antivirus to identify & protect). Persons with no antivirus on their computer’s don’t even know they’re infected. Damage is high.

Scenario 4: Everyone has #4 computers. Herd Immunity is not enabled as there are no protected vectors.
Result: viruses, trojans, and malware spread rapidly throughout connected networks undetected (as there are no antivirus to identify & protect). Persons with no antivirus on their computer’s don’t even know they’re infected. Damage is extremely high.

Conclusion: People who think they can’t/won’t get infected because they’re ‘smarter’ than badware, can & will eventually get infected because they don’t have antivirus active.
