well , I cant help you “asap” with such information .
first moss is not a virus , then you dont need to upload moss on mediafire ( I think I already have a copy of it ).
but I need information about your environnment ( OS , video etc.. ) and the simplest is to share a ZIP from a short session ( before a crash) and a 2nd from crashed session
first will give me technical information and second should have a crash dmp in or beside the zip
get help form a friend if some issues are too technical
