Autocom, I think, is a brand known for car diagnostic tools. Autocom CDP (Car Diagnostic Program) is a product they offer. Autocom CDP 2021.11 could be a version of their software. Keygen is short for key generator, which is a program that generates activation keys for software, often pirated. So a "verified keygen" for Autocom 2021.11 might be a cracked version of their software that some users are trying to legitimize. But using pirated software is illegal and unethical. Need to address that in the article.
