A technician has verified a computer is infected with malware.

Malware is malicious software that can cause damage or harm to a computer system or network4. A technician has verified a computer is infected with malware by observing unusual behavior, such as slow performance, pop-ups, or unwanted ads. The technician isolates the system and updates the anti-malware software to prevent further infection or spread of the malware. The next step is to run repeated remediation scans until the malware is removed. A remediation scan is a scan that detects and removes malware from the system. Running one scan may not be enough to remove all traces of malware, as some malware may hide or regenerate itself.
