Gents,
Valueclick is an "AdBot"
There's a program called Spybot below that eliminates them.
SpyBot- - Search & Destroy searches your harddisk for so called spy- or adbots; little program modules that transmit advertisements to your computer – and information about your surfing behaviour to the net. It can remove those bots, and also some of the tracks you leave when surfing: cookies, the list of recently visited websites, etc..
