Antivirus software effectively detects and blocks most malware on consumer computers.

Is it true that antivirus software effectively detects and blocks most malware on consumer computers?

Partly. Evidence is mixed and only partial: one skeptics discussion reports high detection rates for known viruses while conceding zero-day effectiveness is unknown, and a textbook and a prototype paper assert antivirus detects malware, but several 2025 evasion studies and an arXiv paper document that malware can still bypass antivirus detectors.
