What’s the difference between – Antivirus and Virus Protection?

Any Difference?

And I’m planning to uninstall avast antivirus because i already have McAfee Virus Protection but I’m not very sure yet. avast antivirus automatically tells me if what I’m download is spyware/adware/virus but with McAfee, you have to scan it but it doesnt detect as much.

Should I uninstall avast Antivirus?
