Automated Detection of Harmful Content

This document discloses a solution for automatically detecting malicious content by computer security routine executed in a processing device. A user input to a social media application is detected by the computer security routine. The user input indicates that a user wants to share content with at least one other user through the social media application. In response, the computer security routine suspends said sharing and performs, before determining whether or not to allow the sharing, a security check for suspiciousness of contents the user intends to share.
