Norton vs McAfee

Hi:
When I scanned by using McAfee, it was taking too
long to finish. It took about two and a half hours
while on Norton, it took about one and 15 minutes.

Wonder why McAfee taking too long to scan?

Also, once awhile, McAfee at right bottom corner
popping up as warning 'need to scan.'

How often do Anti-Virus can normally need to
perform when the pc has no problem?

btw) I uninstalled Norton in favor to McAfee which
is free through my ISP.

Thanks for your help in advance.
