Why after installing "Windows System Control Center 2.0.0.2 (Windows)" did?

While installing subject program that I downloaded today from your site and at your recommendation, I received a warning from my AVG that there were many suspicious files. I committed them to the virus vault where they were all rated PUP in severity all with name of “potentially harmful program Logger.IAC, HackTools:.DOI,. LO, .OBH, .MOZ, .LQA, .MHC, .OIB, .NTK, .MYI, .CBX, .MVJ, .HEL, .NFX, .IGG, and .OBI”. What’s going on and should I be concerned?
Thank you, Ken Cook
