Step 1: Isolate the Infected Laptop

The first step is to isolate the infected laptop from any network connections, both wired and wireless. Disconnect from the internet to prevent the virus from spreading further. This isolation is crucial to contain the infection.

Step 2: Assess the Extent of the Infection

Before proceeding, assess the extent of the virus infection. Check for signs of data corruption or unusual behavior on your laptop. This assessment will help you prioritize which data to back up first.

Step 3: Use External Media

To safely back up your data, you'll need an external storage device. This could be an external hard drive, USB flash drive, or even a network-attached storage (NAS) device. Ensure it's clean and hasn't been used with the infected laptop recently to avoid contamination.

Step 4: Boot into Safe Mode

Reboot your laptop in Safe Mode to minimize the virus's ability to operate. Safe Mode loads only essential drivers and services, which can help prevent the virus from actively interfering with your backup process.

For Windows: Restart your laptop and repeatedly press the F8 key before the Windows logo appears. Select "Safe Mode with Networking" if you need internet access for downloading backup software.
For macOS: Restart your MacBook and hold down the Shift key until the Apple logo appears. This will boot your laptop into Safe Mode.

Step 5: Backup Your Data

Now that you're in Safe Mode, it's time to start the backup process:

Windows:

Use Built-in Tools: Windows has a built-in backup utility called File History or Backup and Restore. Use it to back up your files to your external storage device.
Third-party Backup Software: Alternatively, you can use trusted third-party backup software like Acronis True Image, EaseUS Todo Backup, or Macrium Reflect.

macOS:

Time Machine: macOS users can use Time Machine, Apple's built-in backup solution. Connect your external drive and set up Time Machine to initiate the backup process.
Third-party Backup Software: If you prefer third-party options, you can use applications like Carbon Copy Cloner or SuperDuper! for more control over your backups.

Step 6: Scan the Backup

After completing the backup, it's essential to scan the external storage device with reliable antivirus software. This will ensure that the backup files themselves are not infected.

Step 7: Wipe and Reinstall

With your data safely backed up, it's time to wipe your infected laptop's hard drive and reinstall the operating system. This step is crucial to remove the virus completely.

Step 8: Restore Your Data

After reinstalling the operating system, you can safely restore your data from the external storage device using the same backup software or utilities you used initially.

Backing up data from a virus-infected laptop can be a delicate process, but by following these step-by-step instructions, you can ensure the safety of your valuable information. Remember to keep your antivirus software up to date, practice safe online habits, and regularly back up your data to prevent future virus-related headaches.
