Very quickly update, I made a post in the vogons Forum providing some hashes for Teamspeak 3 clients and servers, as well for Teamspeak 2 clients and servers. Unfortuante I couldn't post links over there, but at least I provided useful information such as the file hashes of the original, untouched files. Now at least you can compare the hashes from files you get out there with the originals.
