Playing copy-protected CDs may infect PCs

Mark Russinovich discovered that playing a copy-protected CD on his system lead to the installation of a rootkit – a tool often used by virus writers to hide all traces of their work on a computer- and posted a detailed step-by-step account of his findings on his blog.

According to CNET, the creator of the copy-protection software, a British company called First 4 Internet, said the cloaking mechanism was not a risk and that the cloaking function was aimed at making it difficult, though not impossible, to hack the content protection in ways that have been simple in similar products.

Many commentators on the story have raised the concern that proper notice was not being given to users that new software, which is very difficult to detect and delete, would be installed on their computer. Some have even questioned the legality of making such changes on users computers without proper consent.
