AVG icon/E-Set (play on eset?) seems familiar.

edit : could not get to run in a vm or sandbox and I'm not able to use a real machine atm. If someone could show some screen that would be much appreciated :)

Found a way to run this in a VM: create a file called "nvm.ch" at the folder of the dropper, %programfiles%\E-Set\, and %windir%\system32

Oh my... this FakeAV steals the AVG logo and interface, rips off ESET's name AND copies Norton and Panda (and probably BitDefender as well) to fill the web site

This is an older loader I believe will install what you want, I will grab the other identical looking loader off my test machine later today.
