Suspicious advert activity

During testing phases of my site (which is still largely incomplete), I had an advert that hijacked my page and redirected me to this fraudulent adobe site and attempted to automatically download 'setup.exe' with the excuse it was an update:

update4.flashes-player.us/Player1/C/update-uk.php?installer=Flash_Player_11_for_Other_Browser s&browser_type=KHTML&dualoffer=false


The above link is clearly fraudulent as this is the correct URL for the download page:
get.adobe.com/flashplayer/?promoid=JZEFT

Which is obviously 'adobe.com' and not 'flashes-player.us'.

I do not know which advert it is, but I think under advertising terms this is in breach of terms and conditions.
