Now those are some lucky kids.
I never heard of that removal though I prefer to uninstall Mcafee prior to big windows updates and reinstall after. Best to ask tech support and see what they say. They also can tell you how to get back your Mcafee installs. Did you register them if so you can download them from the account created. If not support will assist you and if you do not get a solution ask to escalate the issue.
Does the documentation have any Mcafee registration cards or similiar? Do the Asus laptops come with a resore disk to go back to the base / as bought config?
