i doubt that famous sites like Filehippo wont add malwares to the files..
""Can somone direct me to a clean one that wont update constantly""
updating constantly doesn't mean that it has malware... its an option you choose while installing the codec pack.. while installing Klite choose advanced mode and deselect update option (( like it comes at end of installation))....
i hope that klite update on you pc is because of your selection while installing, not by filehippo or any other malware
