But I blocked in my windows host file this souurc of annoying flash ads.

127.0.0.1 ad.example.com # Example

How is it possible, that I see suddenly again their ads?

ad.example.com

I don't see anything in there that would circumvent an entry in your hosts file.

Only this line do I not understand, but even if it pulls content from that subdomain, an entry in the hosts file should always block it.

<OAS URL=front.example.com/front@Position3> 

This may be something related to Windows. Perhaps posting in either the Microsoft Windows OS Usage - NT - XP - Vista [webmasterworld.com] or the Microsoft Windows 7 Operating System [webmasterworld.com] forums will get a better response?
