Guess it's Panda time for that nice Ryzen system. Go for it.
Here is the boot time (including system readiness time) with Windows Defender enabled for re-evaluation purposes. Fast startup is disabled and BIOS quick boot is likewise OFF. The video had stated 59 seconds for that test machine w/Defender on system.
Way too many machine/user variables to make a blanket statement. But it is interesting. Frankly I'd expected Malwarebytes to do better performance-wise, but that was not the case, it seems.
