This software, often called "crapware" or "crapplets" in the business, can be a real pain to users. They slow down new computers, make them unstable and can cause downright confusion.
Word is spreading about the latest development in crapware: An obscure software component on Dell PCs redirects certain browser operations to a special Google search page, one overflowing with ads. The component, officially called the "Browser Address Error Redirector," takes over on address bar typos and other errors and thus interferes with some other software that performs the same function more transparently.
Its getting hard enough these days to avoid the Google Toolbar, which is pushed on you by many other packages, including the Java runtime. But this is unrelated to the toolbar. OpenDNS, one of the companies whose software is impeded by the BAER, says that the program "borders on being spyware."
Crapware makes money for OEMs. You pay to get a copy of Microsoft Office on your computer, but almost everything else, from the 90-day trial of Norton Antivirus to the AOL client to the QuickBooks trial to the Sonic RecordNow software to the Yahoo! Music Jukebox is on there because the software company paid the OEM to put it there. It goes further: Lets say you "convert" that copy of Norton Antivirus and buy the full subscription: the OEM gets a cut for that, too.
In this case, Google is probably paying Dell to put this software on the PC, but they are also probably getting a cut of the ad revenue, which gives them both a good incentive to overload the upper part of the page with advertising.
So crapware isnt in there to do you a favor, its in there to make money for the OEM. Yes, they have an interest in you having a high-performing and stable PC, just as they have an interest in world peace, but its a viciously competitive business and they need whatever revenues they can get.
