Performing a full system scan with antivirus software is a crucial step in keeping your computer protected from various threats. Here's a step-by-step guide on how to do it:
- Launch your antivirus software: Locate the antivirus program on your computer and open it. You can usually find it in the system tray or by searching for it in the Start menu.
- Access the scanning options: Once the antivirus software is open, look for the scanning options. They are usually found in the main dashboard or under a tab labeled "Scan" or "Scan Options."
- Select a full system scan: Within the scanning options, choose the type of scan you want to perform. In this case, look for a "Full System Scan" or a similar option. This scan will thoroughly check your entire computer, including all files, folders, and system areas.
- Customize scan settings (if needed): Some antivirus software allows you to customize certain settings for the full system scan. For example, you might be able to choose whether to scan compressed files or setup specific exclusions. If you're unsure, it's advisable to keep the default settings.
- Start the scan: After selecting the full system scan option and adjusting any necessary settings, initiate the scan by clicking on the "Start" or "Scan" button. The antivirus software will then begin scanning your entire computer, analyzing each file and folder for any potential threats.
- Wait for the scan to complete: Depending on the size of your computer's storage and the speed of your antivirus software, the full system scan may take some time. Be patient and allow the scan to run to completion. You can usually monitor the progress of the scan through a progress bar or a percentage indicator.
- Review the scan results: Once the scan is finished, the antivirus software will present you with a report that summarizes its findings. This report may identify any detected threats, such as viruses, malware, or suspicious files. Take the time to carefully review these results.
- Take appropriate action: Based on the scan results, your antivirus software may offer different options, such as quarantining or deleting infected files, repairing damaged files, or ignoring certain files. Follow the recommended actions provided by the software to mitigate any threats or issues it identifies.
- Schedule regular full system scans: To maintain ongoing protection, it is recommended to schedule regular full system scans, ideally once a week or as per the antivirus software's recommendations. This will help ensure that your computer stays secure.
Remember that each antivirus software may have a slightly different interface and options, so the exact steps can vary. It's always a good idea to consult the user guide or help documentation of your specific antivirus software for more detailed instructions.
How to check if your antivirus software is working properly?
To check if your antivirus software is working properly, you can follow these steps:
- Update your antivirus: Make sure your antivirus software is up to date. Antivirus programs regularly release updates to protect against new threats.
- Perform a manual scan: Run a full system scan using your antivirus software. This scan checks all files and folders on your computer for any infections or suspicious files.
- Test with a safe virus: There are harmless files available on the internet designed to test the functionality of your antivirus software, called "EICAR test files". Download one of these files and run a scan on it. If your antivirus software is working correctly, it should detect and quarantine the file.
- Check real-time protection: Real-time protection is an essential feature of antivirus software that actively scans incoming files and monitors your system for any malicious activity. To verify real-time protection, try downloading a test file from a known infected website. If your antivirus software is operational, it should block the download and warn you about the potential threat.
- Watch for regular updates: A well-functioning antivirus software should receive regular updates from the vendor. Check if your software is receiving updates at regular intervals, as this indicates that it is actively maintained.
- Pay attention to system performance: Sometimes, malware can slow down your system, cause crashes or other unusual behavior. If you notice any major changes in system performance, it could indicate that your antivirus software is not working correctly.
If your antivirus software fails any of these checks, consider reinstalling or contacting the support team to troubleshoot the issue. Remember, it is crucial to have an updated and fully functional antivirus program to protect your computer from potential threats.
How to delete infected files detected during a scan?
When you have detected infected files during a scan, you can follow these general steps to delete them:
- Disconnect from the internet: It is wise to disconnect from the internet to prevent the spread of any infection or further damage.
- Verify the detection: Double-check that the files detected are indeed infected. Sometimes, false positives can occur, flagging harmless files as infected.
- Isolate the infected files: Identify the exact location of the infected files and make a note of their paths or names.
- Remove the files manually: Go to the location of each infected file and delete them. You can typically do this by right-clicking on the file and selecting "Delete" or by pressing the "Delete" key on your keyboard.
- Empty the Recycle Bin: Deleted files are often moved to the Recycle Bin instead of being permanently removed. Therefore, ensure you empty your Recycle Bin to delete them completely.
- Update your antivirus program: It is essential to keep your antivirus software up-to-date to protect against the latest threats. Make sure your antivirus software is updated to its latest version.
- Scan again: Run another scan on your system to ensure no remaining infected files are present.
- Reconnect to the internet: Once you are certain your system is clean, you can reconnect to the internet.
Note: The specific steps may vary depending on the antivirus software you are using. It is recommended to consult the documentation or support page provided by the antivirus software provider for precise instructions.
