boot scans

;D is it safe to turn off boot scans or is this a no no ?

turn off ???

the boot scan is used when/if the normal scan find some malware it can not remove…for whatever reason

The boot-time scanner is an expert feature, and was designed to be used when there’s something bad going on on the system.
