What occurs before the crash? Also, what settings did you alter when you activated CF? It refers too the first upload, if you downloaded it now it would be correct. (Date of upload apparently didn't get updated is what I have been thinking, read it somewhere here)
I had crashing problems at first, left most of it as default and screen capture off. I also had too turn on the compatibility mode for lesser graph. cards, of course I had done that the first time anyway.
If we gambled, my money would be on a setting when activating.. which looks like I wouldn't get much of a pay off.
hehe
Best of wishes for you Kermit, I am sure you will get passed this, it is only a matter of time. (Pretty short time most likely)

As for the Trojan issue, try making exceptions for CF maybe?
Otherwise I would suggest turning of the Res Shield or w/e it is for you for the time. You would then want too reactivate it and make an exception for CF and its folders. I am pretty sure this should end the problem.
