Does antivirus slow down PC?
There’s an old theory that antivirus can slow your computer down by 50%. While this may have once been true, it’s no longer a reality. However, your antivirus will have some effect on the overall speed of your device. It’s frustrating when you arm your computer with security tools and then the speed takes a nosedive.
Does Norton Antivirus slow down your computer?
Norton will slow down its running process when another antivirus program is installed and running on your computer.

Why is my computer slow after installing antivirus?

Can you have 2 antivirus programs at once?
While you should never run two antivirus programs at the same time, having two on your system can be beneficial. Most antivirus software (e.g. McAffee, Norton) try to track down viruses on the web and elsewhere to identify them, then send you an update with virus definitions so your system can detect potential threats.

Norton is rubbish. It is the worst anti-virus product currently on the market. At one time it used to be good – before Symantec took over. Norton acts more like a virus and entrenches itself deep into your system.

Norton is better for overall security, performance, and extra features. If you don’t mind spending a little extra to get the best protection in 2021, go with Norton. McAfee is a bit cheaper than Norton. If you want a secure, feature-rich, and more affordable internet security suite, go with McAfee.

Norton is taking up a lot of CPU because Norton stinks and shouldn’t be used in my own personal and professional opinion.
