    Before buying an antivirus you should consider factors such as price, ease of use, compatibility, and support. Installing a free trial version allows an antivirus to be tested in everyday use before purchase.

The article is not convincing because it does not use any comparative statistics. So I made a short one.
The data is taken from the tests in the period November 2022 - June 2023 in the category "Slower launch of standard software applications".

Malwarebytes - 12%, 15%, 16%, 9%, 11%, 7%, 17%, 9% ---> average ~ 12%
Kaspersky .... - 8%, 14%, 10%, 5%, 7%, 3%, 8%, 4% ----> average ~ 7%
Average AV ..- ......9% ...., ......11% , ......7%..., .....10%... ----> average ~ 9%

We can calculate differences:
Malwarebytes - Kaspersky ~ 5%
Malwarebytes - Average AV ~ 3%

So, Malwarebytes can slow the launch of standard applications by 3%. I wonder how many users can feel such a difference.
For example, 3% from 5 s is equal to 0.15 s (a blink of an eye).
Kaspersky is better by two blinks of an eye.
