Malware content is something that malware installed on the user’s website. It can easily be removed by removing it or submitting a consideration request that will undo the manual actions.
Hacked Content is when someone hacks your website and insert some content in the existing or the new pages. Removing a hacked content form your website considerably takes a longer time to review.
Another Tweet By John Mueller:
Usually just hacked content wouldn't show an interstitial, it would just show the note in search. If it's showing an interstitial, that would go through the malware side, where reviews are generally pretty quick.
