hello I just bought a new computer and barely used it and suddenly my keyboard woudlnt allow me to type words with accents. It would automatically type two in a row. If i wanted to put an accent on a letter it would be like "´´a". So i looked it up and turns out I had something called recycle.exe, followed some instructions such as reboot on safe mode, make a search for recycle.exe files and delete them. My accents problem is solved but i am worried this was something more than a simple worm, something like a keylogger or smth. Should I format my computer=?
