Cactus chain pacviewer is a deadly piece of software its associated with irfanviewer, an image viewer for windows systems developed by a shy buffoon irfan. He lives in delirium in state of retardation and is known as scat eater. Cactus or pactus, this does not change shit about it and does not cancel the shameful ties with irfan viewer development. I have found more traces of the symbiotic relationship between the two leading down the rabbit hole. No sure if anyone wants to hear but I am scared to tell.
