Now that you’ve selected your tool, it’s time to create the bootable USB drive. Here’s a step-by-step guide:

Once your bootable USB drive is ready, follow these steps to remove viruses:

4.1. Boot From the USB

Insert the USB drive into the infected computer and restart it. You’ll need to enter the BIOS or UEFI settings (usually by pressing a key like F2, F10, or ESC) and set the USB drive as the primary boot device.

4.2. Scan for Viruses

Once your computer boots from the USB, the virus removal tool should launch automatically. Run a full system scan to detect and remove malware.

4.3. Follow the Prompts

Follow any on-screen instructions provided by the virus removal tool. Most tools will give you options for handling detected threats, such as quarantining or deleting infected files.

5. Tips for Effective Virus Removal

To ensure the virus removal process goes smoothly, here are a few tips:

Even before you need to use a bootable USB, ensure that your regular antivirus software is up-to-date. Prevention is key to keeping your system safe.

Regular backups are essential to protecting your data. In case a virus wipes your system, having a backup can save you from losing important files.
