Can a Virus Escape a Virtual Machine? Exploring the Fact!

With the vast advancement of technology, computer viruses are constantly upgrading themselves. Without a strong antimalware program, getting rid of them is almost impossible. And when it comes to virtual machines, visiting any suspicious website is likely to cause virus adaptation to them. 

But here our main concern is whether a virus can escape a virtual machine or not, or in other words, can a virtual machine protect the system from the viruses? Therefore, we have come up with relevant information that’ll explain the matter – Yes, a virus can escape from any virtual machine under some circumstances

Then without wasting any more time, let’s get into them. 

Can a Virus Escape a Virtual Machine

Is It Possible for a Virus to Escape a Virtual Machine?

Yes, it’s possible for a virus to do so. There are a few yet notable ways that a virus can get away from a virtual machine. For easier understanding, we’re providing them separately by the primary procedure. Here are them –

  1. Using Network Connections

When your virtual machine is connected to the internet, the virus uses it to update itself and gets a way to break through the virtual machine and get into the system. 

  1. Using Shared Resources

A virus can make use of the shared resources between the host operating system and the virtual machine to get out of the machine. The shared resources consist of folders, clipboards, USB drives, etc. Therefore, if a virus somehow gets access to these resources, it can successfully use them to deliver itself from the virtual machine to the host operating system.

  1. Exploiting Virtual Machine’s Vulnerabilities 

This is considered the most common way for a virus to break free from the virtual machine. If the virtual machine isn’t properly configured or if there’s a vulnerability in the hypervisor software, or if there are any other notable vulnerabilities, the virus can exploit successfully.  

Can You Prevent a Virus from Escaping a Virtual Machine?

Preventing a virus from escaping a virtual machine isn’t a big deal. There are some simple precautions that can help you in doing so. So, to make sure that any virus doesn’t escape the virtual machine –

  • It’s better to use any reputable virtual machine program as it tends to be more secure than others. 
  • Avoid connecting your virtual machine to the internet unless you require it most. If you do connect to a network, don’t forget to make use of a powerful antimalware program and a firewall. Use the antimalware program regularly to scan the virtual machine for viruses so that they can be detected and removed.  
  • Disable the shared resources between the host operating system and the virtual machine. Doing so will ensure that the virus can’t make use of the resources and fails to break into the operating system. 
  • Make sure to update your virtual machine program on a regular basis. As you know, software updates usually contain the latest security patches that make the program invulnerable. That’s why updating the virtual machine will protect it from viruses. 

By taking these precautions, the risk of a virus escaping a virtual machine and infecting your computer system will be very low.

Bonus Points

The fact is not all viruses are capable of escaping virtual machines. Some viruses are specifically designed to only infect virtual machines, and they don’t intend to escape to the host operating system. But concerning the other viruses, it’s important to take the aforementioned precautions.

FAQs – Frequently Asked Questions and Answers

Can a program escape a virtual machine?

Yes, it can. In computer security, it’s called virtual machine escape. This process signifies that a program is getting out of the virtual machine with the intention of interacting with the host operating system.

Is it safe to test viruses on a virtual machine?

Even though the chances are slight that viruses spread from a virtual machine to the host operating system, it’s always better and wise to take prominent precautions to make the virtual machine protect the operating system from those unwanted viruses.  It gets ensured due to the isolation. 

What is the risk of the virtual machine escaping?

Virtual machine escape is basically an exploit that lets any hackers or digital intruders interact straightforwardly with the hypervisor by applying code to the virtual machine. Then it makes the host operating system run within it to break free. This way the hackers access the host system and the virtual machines operating in it. That’s definitely a huge risk.


Now that you’ve read this far, it’s pretty assumable that you’ve understood that a virus can escape a virtual machine if it gets any vulnerable point to exploit. So, the best thing to do is take precautions and don’t do anything that can possibly make a chance for the virus to break through.  If you find this post informative and have any further questions, feel free to mention them in the comment section.
