What is the first thing you should do when you discover a computer is infected with malware? The second thing?

Quarantine the computer.

Explanation:

Malware can be characterized with negative software capable of causing various damages to a computer, such as theft of data and information, in addition to damage to devices.

In order to avoid having your computer infected with malware, it is essential to have installed reliable malware-checking software, in addition to taking all appropriate security measures when accessing the internet and never clicking on unknown or suspicious links.

Therefore, when realizing that the computer has been infected by malware, it is necessary to quarantine the computer and immediately disconnect from a network so that it does not infect other computers. The quarantine acts as an action where the infected file is moved to an encrypted folder where the malware cannot be executed and spread by the operating system.
