I somehow believe this is a coincidence what likely happened is something else infected your computer. Or you downloaded Stuffplug from an illegitimate source, if you don't download it from the main site you can't be sure that the file you're downloading is actually a Virus. However Stuff-Plug NG does now contain Screenshot Sender 3, that has got an install script in that some antivirus software recognise as a malicious script...If you selected to install SS3 while installing StuffPlug-NG you may have gotten a warning about a malicious script, however this is not related to the virus you're describing...
