Note that many websites have their own advertising, unrelated to adware.
Adware is any software application in which advertising is displayed while the program is running. The authors of these applications include additional code that delivers the ads, which can be viewed through pop-up windows or through a bar that appears on a computer screen and sometimes through text links or in integrated search results. Adware may or may not track personal information. It may also gather information anonymously or in aggregate only. Users should check the EULA and Privacy policy to ensure if the adware on their machines conforms to their standards.

It also seems to contain components to interfere with the sending of mail from various applications and web sites. However, the function of these files has not been pinned down.
Comment:
ActualNames can silently download and execute arbitrary unsigned code from its controlling server actualnames.com, as a self-updating feature.
ActualNames/BrowseProxy is also a severe security hole as it allows any web site to execute arbitrary programs.
