In theory malicious software could do that in some cases.
Lets take videos as an example. If you are using a media player with an error that could be exploited to execute program code that is embedded inside a prepared (read: modified by the malicious software) video file, this could be one vector of re-infection.
Just what I was about to put. Keep in mind however that this is pretty unlikely, though perhaps it'd be worth Googling the name of the malware to see if it behaves like this. Alternatively you could scan the music, etc, with a virus scanner - they can often find files infected in this way.
