I'm running IE10 on Windows 8 RTM and just saw, that IE suggest some sites when entering something in the address bar. That wouldn't suprise me at all, if I had ever visited these sites, but I haven't. To ensure that no ads have injected these sites into my browsing history, I've deleted my history and cookies without preserving my favourite website data. I also double checked that suggested sites feature is turned off. But even after cleaning my history these sites show up.

Now I'm little concerned what is causing this. Did Mircosoft add these sites by default to make some money (all these sites are commercial) or do I already got some nasty adware?

Edit: Search suggestion are disabled too.
