I had win32/agent.pz but finally removed it using spybot and malewarebytes, the system is clean, however the virus disabled quite a few devices. A majority I was able to fix by uninstalling in device manager and then using the add hardware option in control panel. My audio still shows no audio device. Its a gateway 5310 desktop with an imbedded sound card. The motherboard is Intel Grantsdale- G i915 GV with the audio adapter being Intel 828801Fb ICH6. Ive tried to install the drivers for the above items but I still get no audio. At startup the install hardware pop up shows PCI Device, then the install hardware wizard for Microsoft UAA Bus Driver for High Definition audio. Ive installed that download as well and still get the same results at startup. Im at a loss, do I really need to use the gateway system recovery disc to reinstall windows and go back to square one? I would hate to have to do that after all of this time I've invested in trying to get this computer running correctly. Im desperate for some advice.
