My security center disappeared so how do I look to see if all is working okay. I have McAfee antivirus, but can’t open it, but when I talked to a Dell tech he told me not to worry that I can’t open it not to mess with it, that it’s working fine. So I never need to do an antivirus scan on my computer?

1) How to check firewall,antivirus auto updates are running?
2) Don’t need to do antivirus scans on my computer?

THANKS!
