Remove Vosteran Search (WSE_Vosteran virus) from Chrome, Firefox, IE

Comprehensive analysis of the Vosteran Search browser hijack virus is provided in this guide, with clear removal instructions included as a separate section.

Adware applications, which focus on disrupting one’s web browsing experience for clear-cut moneymaking aims, have populated the global digital environment to occupy one of the firmest niches in the cybercrime underground. The activity of these threats is fairly typical: they are coded to get hold of browser preferences while circumventing the user permission stage. The malicious Web Service Enhancement called Vosteran Search exemplifies this unfavorable tendency with ‘remarkable’ precision. Online advertisements being at the forefront of this adware’s activities, it comes to partially control the outbound Internet traffic on a computer it infects.

Ultimately, victims get directed to the URL of vosteran.com every time they launch their browser, search for something or simply open a new tab. This effect is attained through replacing the user’s preferences with the domain name mentioned above. The affected settings include the homepage, default search, and new tab page. The worst part about this entire interference is that it takes place without authorization. The underlying intrusive add-on called WSE_Vosteran or Vosteran New Tab, which is compatible with Internet Explorer, Chrome and Firefox, modifies the aforementioned preferences and keeps the user from restoring the previous values, hence the constant diverting to vosteran.com.

Vosteran Search landing page

The page is designed as a search provider, much like the ones that everyone is accustomed to in their mundane computing. But the loads of ads displayed on each search results page disclose the genuine objectives pursued by the bad guys. Traffic-to-advertising monetization is a goldmine, and the cybercriminals know it.

The way this malign code enters a PC has got some social engineering flavor. The payload is mostly delivered to computers with other programs. Unfortunately, this fact is hardly ever mentioned in the respective installation wizards, though sometimes there is an opt-out opportunity. The applications that pimp WSE_Vosteran are free multimedia tools, video downloaders, and spoof Flash Player updates. It’s therefore a good idea to always examine the setup options for freeware and take a good look at the ‘recommended’ package – there might be a surprise in there that you won’t admire.
