simon1,
Whenever you have an unrequested
trojan downloader, it can dump all kinds of files on your machine, to steal any kind of information.
Some of the downloaders that distribute
ib.adnxs also may send you other malware.
I certainly would be suspicious that it was on your machine and copied some of your passwords when you visited those sites.
You also should be suspicious of any bank accounts, credit card, or other personal information passing thru the machine. (change all those passwords)
One of the infections is summarized here:

VideoFileDownload, if you specifically did that. (You did have
VideoFileDownload on your machine)
Remote Access Infections can be dangerous to you personally, although I am not
absolutely certain you had one. There is at least a suspicion you did have one that "phones home"..
For absolute safety going forward, experts feel it is best to re-install Windows after encountering one.
We have a whole thread in our Public Library about Remote Access Infections:
