pyleaudio.comは安全ですか？

I downloaded a .pdf file from this site and it tried to open it even though i always save and scan first.... anyways it said remote procedure failed, so I looked into the source code of this website and there is so much javascript loaded down with functions, callbacks, ect that as a web designer I recognize immediately as tracking code at the very least, This Web Site may be hijacked by someone else and not the actual site. It is a legitimate company but the code goes way far beyond what any site would ever need, most of it in the header of it so not even seen on the actual page! Also, the code is so mixed up between proper slimmed professional scripting all the way to very sloppy, with 24 validation errors i cant help but for now warn for people to stay away from this site until its resolved.. Hope this helps.. I will return if my PC has been infected and update this
