Under the terms of the settlement Sony BMG will exchange CDs loaded with the rootkit for DRM-free discs. Customers will also be offered a $7.50 cash payment and one free album download, or no cash and three album downloads.
"Submitting a claim lets fans get music that will play on their computers without restriction or security risk, and lets Sony BMG know that consumers care about this issue," said the group in a statement.
"And for those who have not yet protected their computers, it's long past time to download the uninstallers that will sweep that DRM off their systems and eliminate its dangerous security risks."
Malware that exploited the rootkit appeared shortly after the existence of the software was revealed.
