In some respects, the signs that your printer has been infected with malware are similar to the general signs of a malware infection on your computer, the signs include unusual behaviour by your printer, such as not responding to your commands, printing unauthorised print jobs and refusing to install security updates.
There are a few telltale signs that your printer has been hacked: Un-authorized printing jobs− If your machine is printing unknown documents that nobody authorized, your printer may be compromised.
In Windows, search for and open Windows Security, and then select Virus & threat protection . Click Quick scan, Scan options, or Run an advanced scan, and then select the type of scan you want to run. If you choose Quick scan, the scan begins.

Installing antivirus software in Windows
If antivirus software is not installed, HP recommends you install antivirus software. New viruses are created and released often, and without antivirus software, the files and folders on the computer are at risk.
To do that, press Ctrl + Alt + Delete and open the task manager. Then, go to 'Processes' and check for any unfamiliar programs running. To confirm if it is a virus, search online. Once confirmed, highlight it and press 'End Process' to stop it.
Wireless printers can be a security risk because they are connected to your network and are often left unsecured. If a hacker gains access to your printer, they can not only steal sensitive information that you have printed, but they can also use your printer to distribute malware or print fraudulent documents.
Printers aren't usually considered vulnerable devices. But the truth is that modern multi-function printers face various threats and vulnerabilities. Anytime you connect a device to your network, you are taking on some security risks; printers are no exception to this rule.
Your printer is a gateway to the rest of your network, assuming the printer is network connected. Because printers are a weak spot in many networks, hackers often target them as a way to get to the computers and other servers.
Hackers can directly access your printer if it's not password-protected or if the password is weak. Once they gain access, they can view and print your documents, change the printer settings, and even install malware on the device.
The easiest way to remove viruses is by using an antivirus program designed to clean your system safely. If a virus is already on your computer, however, you may need to run this program under very specific conditions.
Like the real thing, computer viruses replicate themselves, spreading through your operating system and network. At the same time, the virus is wreaking havoc: it can damage programs, delete files, and make devastating changes to your hard drive, all of which can result in reduced performance.
Protection from unknown threats: While free antivirus solutions can protect against known viruses, most cannot detect unknown threats, or malicious files whose signatures the system has not yet identified. Most premium antivirus tools protect against both known and unknown or yet-known threats.
Windows Security is built-in to Windows and includes an antivirus program called Microsoft Defender Antivirus.
Norton is a much better antivirus software than McAfee.
Based on independent and our in-house tests, Norton has better malware protection rated, more features, brings more value for your money, and offers great customer support options.
The most common symptoms of a computer virus infection are…
Programs or files become missing. Corrupted files. Your computer restarts in unusual ways. Some files or programs suddenly don't work properly.
Instead, the virus is detected directly from the suspect source. Direct detection methods usually involve sophisticated techniques, including nucleic acid and immunological detection.
