If your laptop is still under warranty I would get it looked at. There is no way a laptop of that age should be playing up. But, it also depends on what software you have installed (and whether it is required e.g. so called tune-up programs or non-essential security programs), how many programs are starting up with your computer, how much memory the system has available.
When choosing a new anti-virus, go to an independent, professional review source: https://www.av-comparatives.org/ and their 'real world' tests https://www.av-comparatives.org/dynamic-tests/
You can see that McAfee suffers from a high rate of false-positives and has an unhealthy compromise rate compared to some of the other products tested. However, you need to examine the statistics over the long-term so look at several of the test results and then move on from there to determine if the product of your choice is suitable for you and how you use your laptop.
