Can a virus/malware free back of windows folder placed on the same hdd be infected with malware/viruses.Or this kind of backup is impervious to viruses.?Thank you.1 person needs an answerI do too

Yes, it can.

An if place on external drive, then it should not be affected.But if i create a backup with the backup utilities from antivirus programs then is it impervious to viruses/malware, and place it on the same hdd.
