It’s very arguable whether a computer user who is constantly encountering browser redirects to vosteran.com is doing okay cybersecurity-wise. Grounds for such an assumption are strong, considering the fact that this activity is powered by malicious software called WSE_Vosteran. What this article encompasses is a description of this adware and do-it-yourself removal how-tos.
Vosteran Search is a fairly common sample of browser hijacker differing from the crowd in the rapidity of propagation. To begin with, just a quick overview of this infection species: hijackers, most frequently acting to advertising’s advantage, are written to change browser preferences on whatever computer they install to. This results in the rerouting of web traffic over to sites known as “landing pages”, which either advertise something directly or further redistribute user visits to third-party domains.
Speaking of WSE_Vosteran, it’s nothing out of the ordinary in terms of this pattern. What’s quite alarming, though, is how fast it’s been proliferating since it emerged literally a few weeks ago. The people who are at biggest risk are those seeking cool features for free, in particular during freeware installs. The reason is some of these apps have sort of a tradeoff hard-coded into them, not charging the clients for using their services but containing other applications inside the setup. This approach being pretty widespread these days, the bad part in this specific case is that the bundle is not necessarily indicated on the surface – it’s usually some unnoticeable box ticked, which most web surfers do not pay attention to.
The Vosteran adware, when it finds itself inside a workstation after the above-mentioned latent install, will add an extension or toolbar to IE, Firefox and Chrome. The add-on needn’t ask for permission to deploy its routine simply because it’s been programmed that way. It modifies the following settings to vosteran.com: browser homepage, search engine by default, and new tab page. It doesn’t take a rocket scientist to understand what this means – you get your browsing trapped in a redirect loop. Vosteran.com will get resolved pretty much whatever you do online: the browser gets opened – there it is, you trigger a new tab – bam, you want to look for something on the Internet – same story. Why vosteran.com and what’s so special about it to the malware authors? It’s a rather typical landing site involved in a far-fetched traffic monetization model. More visitors means more money. But why should the infected users care? This is a logical conclusion that makes WSE_Vosteran a must-remove app. The best practices of present-day adware removal applicable to this particular pest are provided in the part below, with easy steps and detailed illustrations.
