I have managed to download a boot secter virus What damage will it do and how the hell do i get rid of it? AVG and Malware bytes cant find it. It is properly dug deep in the drive. It has messed with the sound on my PC and has also somehow messed up Google chrome. I have had to come on using IE which keeps opening other windows by it's self and going to dodgey sites Is it a case of wiping the hard drive and booting from a floppy? Also is it safe to save anything i want to my external drive or will that also get infected?
