You can download AnalyzerXP 3.5 from this post. I am still working on a few things that will be different and/or correct on the next version but for now the current version's scanning is powerful and good enough.

As far as the startup entries go, you can easily do that by using the freebie Startup Control Panel. First disable the ones I mentioned by unchecking (clearing) the boxes next to them and reboot. If for any reason you change your mind or want to play around with others, reverting back the changes will be a snap!

For your sound problem, check the Device Manager (Start > Run > devmgmt.msc > OK) to make sure nothing related was disabled or shown as problematic on the list. If all was well in there, I suggest downloading and installing the latest drivers, even if you had them installed currently.
