Running an antivirus scan for malicious software is the first step that a support technician should do when a user reports a virus on a PC. The antivirus scan can detect and remove the virus, as well as prevent further damage or infection. Quarantining the host, investigating how the malware was installed and reimaging the computer are possible steps that can be done after running the antivirus scan, depending on the situation and the results of the scan.
