It appeared from a site that was apparently hacked, and the redirect would now go exclusively via the LinkBucks. I had NoScript and RequestPolicy installed in that browser, so I had an escape, and I found later that ABP+ is just being circumvented by it (I had ABP+ there too).
Sometimes one can get LinkBucks re-directs through a Conficker worm infection, but there avast would have alterted. What I did is block LinkBucks in NS and RP, also checked the SpywareBlaster snapshot. That did not find any changes to the last time the snapshot of my Vista OS settings was made, I looked for specific dll's, nothing there, nor anything out of the ordinary seen to processes in Process Explorer.

SkipScreen, a free firefox extension, comes to help here. SkipScreen is a firefox extension that bypasses the waiting time on Rapidshare and many other sites. The list of sites is given below:
