Dealing with a virus-infected USB flash drive can be challenging, especially when it contains important files. Viruses can hide or even delete your files, making them seem lost. However, with the right approach, it is often possible to recover these files and remove the virus from the USB drive. This article will guide you through the process of recovering virus-infected files from a USB drive and safely removing the virus.
