Strange video settings problem

[x__CRASH__x]

I had a malware attack this past weekend, and in the course of getting rid of it, somehow my video settings in IL-2 got changed. No big deal. However, I've run into a problem setting them back.

I got into the game to drop the landscape detail from Perfect to Excellent. I hit "apply" then back out. I then go into the Config.ini and make a couple adjustments there (Forest=0, and a couple more) I hit Save, close it, then go into the game. I check the video settings... back to Perfect! I switch to Excellent and back out, check the Config.ini and the settings are back to orginal!

I changed the Config.ini to read only, which saves the settings. But the game still reverts back to Perfect when I open it up.

Anyone have any idea what is causing this?
