Answer:
download pop-up
Explanation:
Download pop-up (otherwise known as pop-up download) is an alert, modal or pop-up window that prompts a user to download a particular program. This program might be a malware. So once clicked, the program may automatically install on the user's computer. Since the program might be a malware, installing such on the user's computer will cause the computer to misbehave. The malware might steal, corrupt or damage files or data on the computer system.
