By excluding files and folders from the McAfee scan, you can prevent the software from unnecessarily scanning files that are trusted or known to be safe. This helps improve the overall scan performance and optimize the security resources of your system.

However, it is essential to be cautious when excluding files and folders, as it may potentially expose your system to security risks. Only exclude files and folders that you are confident are safe and have been verified by reputable sources.

Remember to regularly update your McAfee antivirus software and ensure that your system’s firewall is enabled for enhanced security and protection against cyber threats.

Step 9: Scheduling Scans

One of the most important aspects of ensuring the protection of your system is regular scanning for potential threats. McAfee software helps you achieve this by allowing you to schedule automatic scans on your Ubuntu system.

To schedule a scan, first open the McAfee security software on your Ubuntu device. Navigate to the Scans or Settings section, depending on the version of McAfee you are using.

Configuring the Scan Schedule

Once you are in the Scans or Settings section, locate the option for managing your scan schedule. Here, you can specify the frequency and timing of your scans. It is recommended to run a full system scan at least once a week for optimal security.

Furthermore, you can set the scan to run in the background, without interrupting your regular computer usage. This ensures that your device is continuously monitored for potential threats.

Considering Real-Time Scanning

In addition to scheduling regular scans, McAfee also provides real-time scanning functionality. This means that the software constantly monitors your system for potential threats and takes immediate action if any suspicious activity is detected.

Real-time scanning, combined with scheduled scans, provides layered protection for your Ubuntu device, significantly enhancing your overall security and reducing the risk of cyber threats.

It is important to keep in mind that while McAfee and other security software can greatly enhance your online security, it is always recommended to practice safe browsing habits and keep your firewall and other security settings up to date.

Step 10: Managing Quarantined Items

After running a scan with McAfee, it is possible that some files or programs on your Ubuntu system may be flagged as potential cybersecurity threats and moved to quarantine. Quarantine is a secure location where McAfee stores potentially harmful items to prevent them from causing harm to your system. In this step, we will discuss how to manage these quarantined items.

Viewing Quarantined Items

To view the list of quarantined items, open the McAfee software and navigate to the “Quarantine” section. Here, you will find a comprehensive list of all the files and programs that have been flagged by McAfee. Each quarantined item will have its name, description, and the reason it was flagged as a potential threat.

It is important to regularly check the quarantined items list to ensure that no legitimate files are mistakenly flagged. Sometimes, legitimate files or programs may be falsely identified as threats. If you find any such items in the quarantine, you can restore them to their original location.

Restoring and Deleting Quarantined Items

If you believe that a quarantined item is a false positive and is not actually a threat, you can restore it to its original location. To do this, select the item from the quarantine list and click on the “Restore” or “Allow” option. McAfee will move the item back to its original location on your Ubuntu system.

On the other hand, if you are certain that a quarantined item is indeed a security threat, you can choose to delete it permanently from your system. Select the item from the quarantine list and click on the “Delete” or “Remove” option. McAfee will remove the item from quarantine and delete it from your Ubuntu system.

It is important to exercise caution when dealing with quarantined items. Make sure to carefully review the details of each item before deciding to restore or delete it. If you are unsure, it is always recommended to seek assistance from a cybersecurity professional.


Managing quarantined items is an essential part of maintaining the antivirus protection offered by McAfee on your Ubuntu system. Regularly reviewing and managing the quarantined items list helps ensure that your system is protected from potential cybersecurity threats. By understanding how to handle quarantined items, you can make informed decisions about whether to restore or delete them, allowing you to keep your Ubuntu system secure and protected against potential threats.
