Hey. This may not be related, but this issue started when my Webroot Spysweeper encounter a trojan, which was Quarantined after it found it. At this point the system sounds stopped working (start up, clicking on items, etc), but I could play music using Winamp. I did some searching on the net and performed a few of the recommended tasks to fix this issue.

The problem is is that no sounds will play at all now and I get the PC speaker beep when windows loads, and also when I am asked if I want to close a box (like mozilla in the Task Manager). Also, and this may be as a result of the PC installing/looking for other drivers (not SURE), but each time I load up windows (from a restart) it locks up my internet browser and I need to close it (which takes ~15 min to close) since it goes to the not responding state. I will attach a PICTURE of the items in the device manager and maybe you can guide me on what to do?? I'm really fed up with this and I cannot find the correct driver or what to do. I tried downloading a driver off of Dell's website, since I think they have the rights to the version I need, but I was thinking that the correct driver is probably still on the PC somewhere.

My motherboard is

1. How do I stop all the Microsoft Kernel ..... items from being installed each start up?
2. More importantly, how do I get SigmaTel High Definition Audio to work again?

I hope I didn't forget anything. The PC works fine otherwise. Any HELP would be so greatly appreciated. This has been going on for 4 or 5 months and I can't seem to find a good resolution elsewhere.
What's the name of the Trojan?Your audio drivers are here
BTW, the EASIEST way for you to get Dell Support is to enter the Service Tag Number located on the bottom of the laptop.
