that's a tough read! I was wondering if you could describe the issue? from the look of it, it seems that your SQL server is configured to corrupt data? When does the issue occur? During updates, running scripts? I'm no pro. I can just surf around to help. Interesting file though, although I didn't enjoy the website! , funny you should mention AVG as that website has ads precisely like AVG's. You also have Norton installed, geekU has said time and again multiple anti-virus programs is a bad idea!
In either case, if you could elaborate I will look it up and see what I can find on the matter. Hope your business isn't suffering, huh? It's encoded, which isn't even really a topic I stare at if it isn't in letters and numbers, I'm very unfamiliar with the matter.
