Also called antivirus software. Virus Protection Software can detect viruses on a computer, delete viruses, and continuously scan for viruses to prevent infection. This type of software typically runs in the background providing 24/7 protection from virus attacks. Virus protection software is not often installed on Apple mobile devices because Apple says they are unnecessary. One reason is that the apps downloaded from Apple’s App Store are free of viruses. Virus protection is more popular on Android mobile devices where apps can come from anywhere.
