Is Twitpic distributing malware through advertisements?

I saw the first of these ads today on Twitpic, one that say “I’ve been tagged” in three photos, and clicked it with curiosity on whether Twitpic started photo tagging on its system or not. It was the official account of the magazine I’m working for, hence it was important to check if the content was appropriate.

After I clicked the ad, it redirected me to an executable file named “etype_setup.exe”. Certainly, I haven’t downloaded or installed the executable on my system. But, since these ads are obviously misleading users to an installation file without any proper description and warning, it feels like a stinky situation.

Is creating its own botnet a new business model for Twitpic?
