You need to take immediate action to contain malicious code and prevent data loss or damage to your machine. A clear mind and the following simple steps can help prevent the virus and restore your device to its proper working order:


Isolate the machine

The first step in managing such a cybersecurity issue is making sure that it does not infect other computers on the same network. Make sure it’s offline to avoid cross-contamination with other computers that are otherwise “healthy.”


Start the cleanup process

When you are done isolating the machine, you should now attempt to remove the virus from it. It is essential to choose an efficient removal instrument. It depends on the types of threats; thus one should pick the one designed specifically for the very virus. The right antivirus solution should have updates and patches available that will deal effectively with the current threat.


If you have not updated your antivirus software for a while, it might be time to do so. This step will require reconnecting to the internet. However, instead of using a home network, you can create a private system to avoid harming other computers.


Restore the computer

Depending on the severity of the virus attack, it might be necessary to restore a computer to its default or factory setting. This will wipe out everything, including your files and programming additions. It is, however, a very effective way of dealing with a virus and its residual damage. After all, the virus might have done irreversible file damage already, so it is better not to take any chances at times. Also, starting with a clean slate makes the most sense.

Reinstall programming

After you have wiped out everything, you will need to perform a full reinstallation process to enable the computer to run correctly.

Under other circumstances, installing the operating system from scratch will be necessary. You might also have to install all the other programs that you need to use.

       Before initiating the reinstallation process, it is better to have the original software at your disposal. It might also be necessary to find the registration and unique serial numbers for the products you are going to use. It will guarantee an efficient reinstallation process.


Run a virus scan

To ensure that nothing sticks around after the reinstallation process, you should run a virus scan as soon as you are done. It’s best to proceed with a complete system scan to ensure all threats have been successfully eliminated. No matter how many devices there are on your network, it won’t hurt to scan the entire network.

Final step

Consider precautions

If your computer was attacked because you did not have any antivirus program, then now would be the time to get one. The right antivirus solution will help you to avoid potential reinfection. There are several good antivirus software that can offer solid protection to your computer, and you should install and use them regularly.


While antivirus software can be suitable for protecting your computer, you should also take steps to frequently back up your data. Some of the best antivirus solutions come with this option as well. This can provide an added layer of security and lessen the blow in the event of an attack.
