I want to reformat my computer but I want to make sure first that when I do, I won't keep files that are possibly infected. Note that any antivirus/antimalware tools I download are possibly corrupted so please tell me if there's a way to pinpoint the infected files without using such tools. Note also that I've been keeping the said files even before the intrusion on my system was made. How can you tell if a doc/jpg/mp3 file is infected? Is it possible to infect the old files without suspicious signs being apparent?
