magna86 - Thank you very much for your advice. I will run the suggested tools and post the logs when I get back from work later today.

I’m afraid to say that I have already broken one of your rules. Following a link in a Microsoft forum thread, I downloaded and ran SpyHunter from Enigma. I realized that this was basically a ploy to get me to purchase their product and uninstalled it. Hope that didn’t mess us up too much. Other than that, nothing else has been attempted since the logs posted yesterday.
