This question already has an answer here:
In the context of a) information security and b) an operating system such as Windows 10 or OS X, what actually constitutes a "hack"? Most non-technical end-users associate the term "hack" with the deliberate stealing of information or an event where somebody had unauthorised access to their data. However, the CSO website seems to have a much broader definition of a "hack" to include fake AV messages, pop-up messages and browser redirects.
So if you were documenting a problem with an end-user system which had "pop-ups", would you really feel comfortable in reporting that the system was "hacked"?
