It’s best not to run more than one antivirus/malware application as they interfere with each other and actually reduce protection.

In reality programs like the free Avast covers all aspects of the above programs you mention and much more, so is the only type you need.

The Windows firewall is good for most usage and only needs upgrading if you have very sensitive information on your computer.

Hope this helps
