Download multiminer from the link provided and while I was browsing through the GUI I got popup saying my computer was compromised... Looked like some type of fake virus alerts, some type of malware. Good experience for my first time trying to do this!
Many mining programs trigger AV software. I've never used multi-miner, but Timelord2067 is fairly touchy about security.
A quick look through the thread shows that support might have dropped off for the program.
Also, I don't see support for nVidia.
