Yes, a GPU can potentially get a virus or malware if the system it is connected to becomes infected. However, the GPU itself is not a target for viruses as it does not have its own operating system or storage.
Graphics cards are an essential part of computers and laptops, allowing them to display data on the screen through a graphical interface.
But, if you have ever wondered whether or not graphics cards can get viruses like the rest of your computer.
It’s not the most common vector of infection, but it can happen, and knowing how to guard against viruses on your graphics card is an important part of being a knowledgeable computer user.
Read on to learn more about this risk and how you can cut your exposure to it.
Can a GPU Have a Virus?
Yes, Your Graphics Card Can Get a Virus
One of the most common questions we get asked is whether or not your graphics card can get a virus.
The simple answer to the question “can a GPU have a virus” is yes. But there are some things you need to know about why that’s the case and what you can do to cut your risk of getting attacked by malicious software (malware).
Let’s dig into the details of how graphics cards work, why they have access to other parts of your computer, and how malware can spread through them.
Types of viruses that can potentially infect a GPU
|Type of Virus||Description|
|Malware||Software designed to harm or exploit a computer system|
|Ransomware||Malware that encrypts a victim’s files and demands a ransom to restore access|
|Cryptojacking malware||Malware that secretly uses a victim’s computer to mine cryptocurrency|
|Adware||Software that displays unwanted advertisements on a computer|
|Spyware||Software designed to gather information about a person or organization without their knowledge|

How Do Viruses Spread To Graphics Cards?
Viruses can spread to your graphics cards in 2 ways.
- Direct contact
- Through software
Direct contact occurs when you insert a disk into your computer’s disk drive that has an infected file on it.
If the virus is came from the disk, then the virus can transfer to your computer. Software viruses are more likely to infect your graphics cards. The reason is that they’re not connected to the disk. Like they would be if you were inserting it into your drive and booting up the virus.
The virus instead spreads by attacking the program you’re using and creating an infected copy of itself.
You might think this doesn’t apply to graphics cards. But many people install games with programs on them onto their computers. They do this without realizing that there could be hidden malicious code inside those programs.
It’s also possible for a virus to come through email attachments. So make sure that you don’t open emails from unknown sources.
Finally, most video game emulators require downloading files from the internet. So if you don’t want to risk getting a virus on your graphics card, avoid these types of programs altogether.
What Symptoms Indicate An Infected Graphics Card?
While graphics cards are not susceptible to the same viruses as computers, they can still be infected with malware which will seriously reduce performance and make your computer unusable.
The most common symptom of an infected graphics card is extremely low framerate in games or other graphic-intensive programs.
To check if your graphics card has been compromised, visit PC Pitstop. It will let you know if you need to run an anti-virus scan on your system.
If PC Pitstop finds something wrong, it will provide more detailed information about what might have caused the issue and how to fix it.
For example, they’ll recommend installing a specific driver update. After following their instructions, it should resolve any problems you were experiencing with your graphics card.
If you’re experiencing this issue and suspect it might be related to malware on your graphics card, you can use anti-malware software like Malwarebytes to scan for and remove the offending program.

How Can You Clean An Infected Graphics Card?
While graphics cards do not have hard drives that can get infected with viruses, they can still be infected.
If you have an infected graphics card then it is best to take the following graphics card virus removal steps to clean it:
- Start your computer up in safe mode and run a virus scan.
- Boot into recovery mode and format your hard drive and reinstall windows or your operating system.
- Update all of the drivers for your motherboard, graphics card and other components inside of your computer.
- Run a full system scan again to make sure there are no more infections.
- Reboot your PC and make sure everything is running smoothly without any issues.
- Repeat steps 1-5 until the problem goes away.
- Remove any extra software that could cause problems on your computer such as games, browser add-ons, utility programs etc.
- Put a firewall on your computer and create some rules. So you will know when something is trying to connect to it over the internet.
- Keep antivirus software updated and installed.
- Be careful what kind of files you download from the internet. 11) Make sure your network security settings are high enough. So hackers won’t be able to easily access your computer wirelessly from outside of your home network.
How can you prevent a virus from infecting your graphics card?
There are many ways to prevent your graphics card from being infected with malware. One of the most common is to run antivirus software on your computer.
If you don’t have antivirus software installed on your computer, there are plenty of free options available online.
A second way to protect your graphics card is by installing an anti-malware program like Malwarebytes Anti-Malware or Adaware Antivirus and running it periodically.
In addition, you must keep all of the programs on your computer up-to-date. So they’re less likely to be exploited by malware. You should also stay away from suspicious websites and attachments in email messages. Even if they seem to come from friends.
Finally, if you notice any unusual behaviour on your computer such as popups that won’t go away or slowness when opening programs, stop what you’re doing immediately and contact your IT professional for help.
The best way to protect your graphics card against viruses is to update your device drivers whenever new versions are released.
These updates usually include fixes for newly discovered vulnerabilities and patches for existing ones too. Both of which might otherwise leave your graphics card open to infection.
You must take precautionary measures to prevent your computer from getting a virus such as installing antivirus software or changing your passwords regularly.
