As David said, it is very likly that you have a lot more files compromised and modified. Once someone is able to get into your site they modify lots of different files in order to give them as much exposure and chances of always having a hacked site accessable again.
If they spam is coming from libraries/rokcommon/Overrides it mean that they most likly modifed those files in order to do sending of spam. This is probably not ther point where they compormised your site.
