Unforunately, UAC was never disabled on my system, and the malware easily circumvented it.

As for the malware, Avast must have just figured it out this morning. After updating last night and getting nowhere - I booted up this morning and Avast figured it out after updating with a fresh update, so apparently I got a bleeding edge virus that Avast just got protection from. (Either that or they realized it from my post)

Avast did a boot scan, and I deleted the malware this morning. Unfortunately, my .exe association is completely broken, so my system is left in shambles. I’ve been attempting to get it running as we speak, and was able to open firefox by navigating to the directory, and running the executable as administrator (somehow this works).

Thanks for the help, and I’m glad Avast released new definitions to protect against this so that others aren’t left in my situation.
