It looks like he is running IE8 or an earlier version.
1. Why would anyone test anything today using IE8? Better yet why is anyone still using IE8 which is total garbage?
2. Why would you open an downloads on download? This is stupid.
3. Also why is he downloading stuff from those garbage websites?
I suggest the tester change to Firefox or IE9 RC and learn that when you download a file you save it to a some place safe so that you can see what is downloaded before you run it.
This has to be one of the worst tests evah
