The StartFenster Virus

Thr StartFenster Virus optimizes the browser for online advertising by replacing the main search engine and the homepage URL with commercial-filled ones.
Still, some users may be concerned about the legal point of StartFenster’s nature. Actually, displaying pop-ups, boxes and other ads is NOT forbidden by any national or international law. The pay-per-click marketing applies to almost all hijackers, as this method ensures that the developers who distribute StartFenster and other ad-generating software will be paid for doing so on the basis of the number of ads you see and the ones you open. In fact, this is an excellent money-making strategy. For such money-earning purposes, many programmers include browser hijackers and Adware in the software mixtures they create. These program packages are known as bundles and contain many diverse programs. Most importantly, you can download them for free, which helps for spreading StartFenster, as users could be very much tempted to check what kind of programs such bundles contain and some might even find it necessary to use a program from such a mixture. Of course, this is not the only efficient distribution method that browser hijackers use. Other ones could be torrents and shareware, as well as movie or video-streaming web pages; spam letters and their corresponding attachments or even documents and visiting contagious websites.

However, you may have done that unknowingly as it usually happens. Everything depends on the feature you choose from the installer.
