During unfortunate circumstances my pc has become infected and so Ive decided to do a full system wipe and flash my bios to be sure however I only have basic knowledge of how to reinstall my OS and format my drives, and I have zero knowledge of how to flash my bios and so guidance would be greatly appreciated. But ive read about viruses being able to save themselves on microcontrollers in usb keyboards and other obscure locations so I would love any advice on what more to clean and what other procedures to undergo to ensure system safety. I also have a bit of a problem, currently im backing up a large selection of images and music to a dropbox account, I want to keep these files after my wipe but I dont know how to ensure theyre clean so help with that would also be greatly appreciated.
