Hi, I recently bought the AVG Driver Update software. Am having a problem with it in that it keeps updating the sound drivers, which then kill the sound to my speakers! I have to roll-it back manually to the previous setting to get sound back. What is going wrong and how do I fix this? Is the product faulty? I shouldn't have to do this - never had a problem with sound before I started using this product!
