Did you check on false positives by BitDefender?

BitDefender Free or paid?
BitDefender Free is known to put files in quarantine,
without asking the user.
That means that in the case of a false positive of a system file,
said file will be moved to quarantine, creating the risk that your
Windows will not start.

Are you sure?
(I would put not a cent on that assumption.)

MBAM and SAS are known to be ADDITIONAL to av-programs.
They can find malware not found by your av-program.
You should run both (after update) to be sure.
Maybe you will be surprised at what they find and your av-program did
not find.

Who can tell?
Did you check on false positives by BitDefender?

Real-time protection without a regular full scan, is not sufficient.

Email scanning is not needed.

What to do:
Use your av-program real-time, update every hour, 
scan frequently (full scan).

Additionally:
Update and scan with both MBAM and SAS at least weekly (after update!)

If you think BitDefender (Free?) is better than Avast (Free?),
then uninstall Avast and install BitDefender.
(maybe will make you feel better.)

Both will have false positives.
Both will screw up occasionally.

Screw up = by updating with wrong updates,
system files will be wrongly marked as infected and will be removed,
after which your PC will be unoperable.
This happened to almost all av-programs sometime in the last years.

But as you make images, that should not be a problem.
