I was looking for a teamviewer that would support older version of ios 5.1* and came across this site : [Link removed by moderator]
Appeared like a fake site.
Thanks for your post.
We will be looking into this matter but always remind TeamViewer users to only download from official TeamViewer sites.
Below you can find all the previous version download links so you can continuing benefiting from using TeamViewer on your devices!
Thanks for using TeamViewer!
