Is it okay to install an antivirus if there is a malwarebytes already?

Norton's ability to provide decent heuristic detection updates has waned in the last few years; that's why the sales 'advisors' in companies like PC World (UK) try to get you to buy it. They have a massive pressure from above because PC World and Norton as companies are in bed with each other, so to speak.

The main free antivirus programs also block attacks in real-time, even Norton; so it's not just Malwarebytes. In fact if you're using Malwarebytes there is no need in having Norton installed at all; MBAM's heuristics are far superior to Norton's!

It sounds like you are saying a real-time Anti-Virus program is not needed if Malwarebytes Pro (real-time) is used.
That's not true and is bad advice.
MBAM is designed to be used WITH a real-time Anti-Virus program.

Here is an MBAM forum thread about this:
Free version vs. the Pro Version...a few questions.... - Malwarebytes Forum

No, if you read what I said there is no need to have Norton installed. A technicality, but one which preemptively wins this "argument" before it starts.

OK, you win the argument.

I said "It sounds like you are saying a real-time Anti-Virus program is not needed".
That was the impression i had reading your post.

Your post/advice did not also state that a person should also use a different AV program if Norton is not used.
That is why i posted as I did.

Sorry i misunderstood...

It was my fault anyway for not being more clear. Editing post in question~

Thank-you for editing to clarify this!
