I'm not sure why a thread was deleted from a user named ShieldsUp, but I thought it was a valid question, that I wish to address. Here is my answer, and I hope it gets the opportunity to be read. If my post also gets deleted, then I will certainly have some questions of my own as to the policies of this forum.
Anyways, my comment to the earlier question is this:
There are possible truths to what you say. My approach to your concept is this: I have this computer that I use for internet access and gaming. It has absolutely 0% personal or sensitive data on it whatsoever.
If I need anything of that nature, I use the second computer, that is not connected to the internet, never has been, never will be. Used for records keeping, account information, etc.. the information contained within it's OS is as safe as one can get.
So, if one of these games happens to be that evil of all evil programs, all the information that will be garnered will be some irrelevant game site passwords, and a couple of forum passwords. Shoot, I'd happily email that information to anyone who asked. :-)
As far as someone using my computer as a possible proxy, I have taken appropriate software and hardware safeguards against that sort of threat. Good luck to any who try. Not that it cannot be done, but it will most assuredly cost more effort that it would be ultimately worth.
At the end of the day, I think that your concerns are probably valid, within an entirely different venue, however. I believe that if a "Global Attack" or anything close to that concept were to occur, it would probably be launched via the venue of cracked and illegal software that is so readily available to 100's of thousands of computer users, wanting something for nothing, or as you term it, the "free lunch" crowd. Much easier to pass code that way, than using a venue like GAOTD.
