What should be done if the computer in the instrumentation system gets infected with malware?
Thread Content
As the title suggests, since antivirus software is generally not installed on instrument computers, the preventive measure is to use new discs that have not been used before. Although prevention and control are effective, if the system computer is still infected with a virus, is it necessary to back up all the files on the computer, then remove the virus or reinstall the system? If virus files are also backed up during the backup process, it seems to be of no use. So I would like to ask the experts here: what should be done if the computer controlling the instrument system gets infected with a virus?
This should still be handled by the DCS manufacturer; they usually provide customized McAfee antivirus software.
Placing the computer in a pressure cooker and steaming it for a while will disinfect it.
1. If the computer at the system operation station is infected with malware, the operation station will not be able to connect to the Internet; it’s unlikely for an infection to occur over the Internet. So someone must have plugged in a USB drive at the control station, haha. Here, our night shift operators watch movies at the control station. This is due to poor management on a regular basis. 2. If it’s an office computer used for monitoring instruments, one can simply back up the necessary files and reinstall the system – it’s not a big deal at all.
Since you think it’s necessary to have antivirus protection, it’s better to take precautions and install antivirus software first. Generally, DCS manufacturers will recommend certified antivirus software brands.
Find a professional system manufacturer to handle it; it’s quite difficult. If the project file is infected, the project has to be redone. Under no circumstances should you handle it by yourself.

Important things definitely need to be backed up in advance; it’s essential to do so to avoid any problems
Generally, antivirus scans can only be performed one file at a time, and backup files may also contain viruses. It is best to consult the manufacturer regarding which antivirus software to use; some antivirus programs can damage the system. If there are early backups that have not been modified, the system can be reinstalled from those backups
