Avast is now installed on the new netbook, and I uninstalled Norton. Should I also uninstall Windows Defender, or is that something different? Does Avast cover pretty much everything?
Thanks to everyone who responded!
Your response will be easier to understand this way.
Windows Defender is an addition layer of protection and can be removed but its not necessary to remove it.
Windows 7 provides default sounds that are OK but the sounds that are provided by the audio driver from provider for Windows 7 are much better.
When I updated to Windows 7 I had Windows sounds but they were tame compared to what I was used to before I updated so I installed the Windows 7 audio drivers for my Gigabyte motherboard that has Realtek High Definition Audio.
I did not want to trust Windows Update as it did not find the Realtek audio adapter present.
I tried to use the CD that came with the motherboard to update the basic audio driver but it would not run on the 64-bit system.
