Spybot-S&D searches your hard disk for so-called spy- or adbots; little modules that are responsible for the ads many programs show. But many of these modules also transmit information about your surfing behaviour and more to the net. If Spybot-S&D finds such modules, it can remove them - or replace them with empty dummies in case their host won't work any more with its bot removed. In most cases, the host software still runs after removing the bot. For a list of 'supported' bots see the feature lists below. Another feature of Spybot S&D is the removal of usage tracks, which makes it more complicated for unknown Spybots to transmit useful data. The list of last visited websites, opened files, started programs, cookies, all that and more can be cleaned. Supported are the three mahjor browsers Internet Explorer, Firefox and Opera. Last but not least Spybot-S&D contains some routines to find and correct invalid entries into the registry.
