I heard that due to system limitations, antivirus software cannot create antivirus and anti-virus functions for iPhone devices. I would like to know if Avast has antivirus and anti-virus software specifically designed for iPhone devices
First I don’t work for Avast nor do I use iOS, so I can’t speak from personal experience.
If it is for IOS computers laptop/desktop program I would say not.
However, there is a version for iOS Mobile - Avast Mobile Security for iOS - Avast Community
