It said "well-known" not "reliable" or "respected"

So, it's true. They are very well known.

Are you able to explain what is wrong with MacAfee? I'm not knowledgeable in this area.

John McAfee left only a few years into the company, and then McAfee AV slowly morphed into one of the most bloated applications in the business, riddled with spyware. They were one of the first to begin selling customer data. Like Norton, AVG, Avast and others are now doing as well.

I'm sure McAfee employs a few smart people but the management is radioactive. They simply do not have a cutting-edge security culture and people are their products, not their customers. Like Norton, they employ scare tactics and Dark UI in order to coerce customers into keeping the software installed. They try to worm their way into default installations so that they can exploit a computer for its entire lifetime.

Kapersky recently released a security bulliten on crypto mining and theft, they may be Russian but they are a crack security team and I would trust them over any of the other companies I've mentioned.

Thank you for the reply. I've only recently started becoming interested in cyber security, I participated in my first CTF late last year. I'm still very uninformed about the wider cyber security culture.
