vista- when turning the virus on, no sound in windows

[HostileReality]

This never used to happen, but now that i have installed everything on Vista, when i turn the virus on, my windows speaker settings change to virus TI audio, and my m-audio dissapears completely from windows sound pannel. I can stil play audio through the m-audio card via cubase, but it seems that whenever the virus it turned on, it overthrows the m-audio and takes over in windows. but i cant find a way to set the m-audio back, without restarting the computer.
