If i were more up-to-date then I'd be here to help. Sadly, I don't know enough anymore.
I'm an owner of a small business and one of my many hats is managing my Win7 and Ubuntu network of computers (on the basis of being a LAN admin and getting a Computer Science minor 15 years ago, while in college). Really though, at this point I know only enough to keep stuff running with minimal functionality.
An infection with a trojan brought me here - it's been many years since my last trojan infection and that was fixed simply with HijackThis; the fixes are much more complicated and many more logs must be analyzed these days!
