Virus belongs to the software class of so-called browser hijackers and is among its latest representatives. causes obvious changes to your main browser’s interface and behavior, hence the name of this software type.
The virus will display pop up ads and messages

When you are trying to get to a certain website or page with information you are looking for, the last thing that you would like to deal with is a stream of ads, pop-ups, banners, and automatic page redirects to other sponsored pages. Unfortunately, web ads are almost impossible to escape nowadays and no matter how hard you try to keep away from them and the sites that stream them, sooner or later you may unknowingly install a browser hijacker like inside your PC and may get swarmed by a flow of unstoppable third-party adverts and other aggressive promotional messages. They may take over your Chrome, Firefox, Explorer or some other browser that might be used as default.

The real problem with these apps such as Poshukach, iStart Search Bar, however, comes when they start to redirect the actual web searches to specific sponsored web locations and impose some potentially unwanted changes (such as homepage or search engine replacements) which force the users to use some third-party tools, toolbars, and components, without asking for their approval.

Most browser hijackers are widely regarded as potentially unwanted due to these activities and some people may even mistake them for viruses or some form of malware (probably ransomware or Trojans) because they can be extremely aggressive in their attempts to take over the main browser and to turn it into a platform for sponsored ads positioning and paid redirects., in particular, is from this category of applications which uses advertising channels and, in the next lines, we will tell you more about it.

Thankfully, neither this app nor any other browser hijacker can be accused of any actual computer harm or criminal actions. That’s why we won’t refer to it as a virus. This is because, despite being highly irritating and even aggressive in its attempts to promote things, is actually a legal piece of software that serves the needs of the online marketing industry and is not used for any form of cyber crime.

Still, we do advise you to follow the instructions in the removal guide below and remove the browser hijacker from your system because such an app may heavily disturb your web browsing and may expose you to insecure web locations where real threats (including viruses, spyware and ransomware) may hide. Besides, if you don’t uninstall the changes that the hijacker has imposed to your browser, every time you start a new browsing session you may automatically get redirected to different sites, third-party platforms, links and messages with questionable origin and unreliable content.

And if the annoyance of the page redirects and pop-ups is not enough for you to remove, the frequent screen freezing, browser unresponsiveness and sluggishness, which such software may cause as a result from its ad-generating activity in the background may add up to that decision. For fast and optimal results we suggest you follow the instructions below or use the professional removal tool which can scan your system and uninstall not only potentially unwanted program like this one but also much more serious infections.
