So I’m planning to backup a Mac which is possibly infected, 10 year old kid downloaded random movie, music, and gaming, and lord knows what kind of files from untrustworthy sites and I installed almost every top anti-virus software: Avast, malwarebytes, cleanmymacx and deleted 5 possible malware and the rest came back clean. Could there be viruses that could bypass antiviruses? If so how do I handle them? And because I don’t want to possibly risk having some invisible virus get into the backup or damage files/infect the disk.
Any help appreciated!!
