Introduction

After discovering your computer has been compromised by a cyberattack, it’s crucial to check your internet connection to ensure it hasn’t been affected. Begin by disconnecting from the internet to prevent further damage. Then, run a full system scan using your antivirus software to detect and remove any malware. Once the scan is complete, check your network settings for any suspicious changes, such as DNS settings or proxy configurations, and revert them to their original state if necessary. After verifying that your computer is clean and your network settings are secure, reconnect to the internet and test your connection by accessing a website. If the website loads successfully, your internet connection is likely safe. However, it’s essential to remain vigilant and keep your antivirus software up to date to protect against future cyber threats.

Step 1: Disconnect from the Internet

After discovering a cyberattack on your computer, it’s crucial to check your internet connection to ensure it hasn’t been compromised. The first step is to disconnect your computer from the internet to prevent further damage. This can be done by unplugging the Ethernet cable or disabling Wi-Fi on your device. Next, run a full system scan using your antivirus software to detect and remove any malware or viruses that may have caused the cyberattack. Once the scan is complete, check your network settings to ensure they haven’t been altered by the attack. Look for any suspicious changes, such as DNS settings or proxy configurations, and revert them to their original state if necessary. After verifying that your computer is clean and your network settings are secure, you can reconnect to the internet and test your connection to ensure it’s working properly.

Step 2: Run a Security Scan

After disconnecting from the internet, the next step is to run a full system scan using your antivirus software to check for any malware or viruses that may have caused the cyberattack. This scan will thoroughly examine all files and programs on your computer, looking for any signs of malicious activity. If the scan detects any threats, such as viruses, trojans, or ransomware, it will prompt you to remove them. It’s important to follow the software’s instructions carefully to ensure that all threats are properly removed.

Once you check your internet connection the scan is complete and any threats have been removed, you should restart your computer to apply any necessary changes. After restarting, it’s a good idea to run another scan to confirm that your system is clean. If the scan comes back clean, you can then reconnect to the internet and check your internet connection to ensure that it is working properly.

Step 3: Check Your Network Settings

After removing the malware from your computer, it’s important to check your internet connection for any signs of compromise. One of the first things to do is check your network settings to ensure they haven’t been altered by the cyberattack. Look for any suspicious changes, such as DNS settings or proxy configurations, and revert them to their original state if necessary. 

You can check your DNS settings by accessing your network settings on your computer or router. Ensure that the DNS servers listed are the correct ones provided by your internet service provider or a trusted source. If you suspect that your DNS settings have been changed, you can manually set them to the correct values. 

Additionally, check your proxy settings to ensure they are configured correctly. If you’re not sure what your proxy settings should be, contact your internet service provider or network administrator for assistance. Once you’ve verified that your network settings are correct, you can reconnect to the internet and check your internet connection to ensure it’s working properly.

Step 4: Reconnect to the Internet

Once you check your internet connection and have verified that your computer is clean and your network settings are secure, you can reconnect to the internet. Plug in the Ethernet cable or re-enable Wi-Fi on your device. After reconnecting, it’s important to check your internet connection to ensure that it is working properly. 

Open a web browser and try to access a website. If the website loads successfully, your internet connection is likely back to normal. However, if you encounter any issues, such as slow speeds or error messages, there may still be a problem with your connection. 

In this case, you may need to check your internet connection and troubleshoot further or contact your internet service provider for assistance. They can help you diagnose and resolve any issues with your internet connection. By following these steps, you can check your internet connection after a cyberattack and ensure that your online activities remain safe and secure.

Step 5: Test Your Internet Connection

Finally, after you check your internet connection and ensure that your computer is clean and your network settings are secure, it’s time to check your internet connection. Open a web browser and try to access a website. If the website loads successfully, your internet connection is likely back to normal. 

However, if you encounter any issues such as slow loading times, error messages, or the website failure to load, there may still be a problem with your connection. In this case, you may need to troubleshoot further or contact your internet service provider for assistance. 

It’s also a good idea to test your connection speed using a speed-testing website or application. This will give you an idea of how fast your connection is and whether it is performing as expected. By following these steps, you can check your internet connection after a cyberattack and ensure that your online activities remain safe and secure.

Run a full system scan using your antivirus software to detect and remove any malware or viruses that may have caused the attack.
