My sister bought a Pavilion 524w a while ago, and it got infected with craploads of spyware. I tried Ad-Aware, Spybot -- everything I could think of to try to get rid of it, but I still couldn't manage to get it all off, so I just backed up her documents and reformatted the hard drive. However, now I can't seem to find sound drivers for her machine on HP.com. Can anyone help me out?

Thanks!
