Just briefly, Blain
I wondered why you had AVG 8.0 and anti-spyware products if you had no net connection.
The logical thing then would be to close, disable or uninstall such programs which weren't going to give you benefit.
Certainly, from a similar experience to yours, I've found running a ~safe~ game in a closed environment to be trouble free, with programs like AVG, ZA, AdAware and Spybot not needed.
I hope some other forum members will weigh in with their expertise. I wish you luck.
