It appears that the Browser Hijacker scene has seen another addition in the face of Vosteran Search Virus. This program may pose as useful software – claiming best deals and the like, but don’t be fooled – its only real goal is to saturate your screen with Ads to sites it is affiliated with. We’ve had reports that Chrome, Firefox and IE users all have trouble getting rid of this pest, so in this article we’ll discuss on the easiest way to remove the Browser Hijacker yourself.

Why were you targeted by an installation of Vosteran Search Virus?

While it may look like it it is certainly unlikely that your computer was specifically chosen to be infected with the Browser Hijacker. The goal of the people behind Vosteran Search Virus is to infect as much computers as possible. You just had the bad luck of obtaining and running on your PC an executable containing the Browser Hijacker. Note that anti-virus programs are not always the best way to deal with Browser Hijacker – the computer security experts treat them as low priority targets, because they rarely damage the computer in any way or steal data and because of this many are considered legal (thought often unwanted). Browser Hijacker can be a pain in the backside to uninstall – here are a few tips on how to recognize Browser Hijacker infected executables in the future.

  1. Emails, even from people you know, may contain Browser Hijacker infected files. Don’t rush into opening the attached files – run them through an anti-malware program first if possible. Keep in mind that people rarely send executable files (ending with .exe) over email. A file named Invoice.PDF is probably legit, the same file as Invoice.EXE or Invoice.pdf.EXE is almost certainly carrying a virus or an Browser Hijacker.
  2. These days it is a common practice to stuff the installer for a program with several other programs as extras. When used in a nice way these extra programs will be trials and demo versions of other programs created by the same developer. Unfortunately much more often your will encounter nasty programs inside – in the likes of Vosteran Search Virus or worse. All of these are usually installed automatically when you select the Quick/Default installation option of the installer.  Make a habit of always using the Advanced option – one of the menus it will give will contain a detailed list of all programs hidden in the installer and you will also have the option to remove any unwanted software for this list. Make use of this feature and remove anything you don’t want.

Remember that Vosteran Search Virus exists to make money for someone, not help you in any way

As an Ad generating software Vosteran Search Virus may create what appear to be lucrative offers from time to time. Don’t let it sway you against your better judgement. It is a shady application and trusted&reputable sites don’t usually advertise through such channels. Any offer you see from the Ads can be a phishing attempt going after you accounts or could simply be convincing fakes. If it is software on sale it is probably actually useless bloatware which doesn’t even work. The only think bloatware applications are good at is to make fake or exaggerated warning messages about problems with your PC. They usually come “for free”, but the only think you’ll get is a scan reporting of the fake problems. People who decide to pay for such software will stop seeing the threatening messages, but that’s just false security. Should anything bad really happen to your machine bloatware is usually unable to fix it.
