I downloaded the free home protection for my kid’s computer and the day that it expired we got a virus that will not allow me to access the internet or download any software. I tried downloading Avast to a disc and installing it via safe mode but that did not work. I do not need any data that is stored on this computer but I have no idea how to wipe it and start fresh without paying someone to do it. I’m sure it can be done, but HOW???
