Questions about redirect

YesSearches is a bogus search engine that has features of a browser hijacker.[1] This potentially unwanted program (PUP) can infiltrate the system unnoticed thru bundling. Once there, it drops Clqvrfsrv.exe, ShortcutBoost.exe and Uninst.exe to launch with every startup. Additionally, it replaces the default search engine and the homepage to domain to start rerouting its victim to sponsored sites. To prevent users from reverting these changes back, the virus also alters the computer's Registry. From first sight, YesSearches might look like a legitimate search engine which includes a Privacy policy, EULA,[2] and optional languages. However, as you must have already understood, it hides shady functionality behind these allegedly useful functions. You should not spend your time dealing with this hijacker. Make sure you terminate it right after it appears on your web browsers.

The main aim of YesSearches virus is infiltrating third-party ads directly into the search results it displays on victim's screen. As a result, you might find difficulties in finding needed information quickly. Reasonable and safe search tools always limit the amount of commercial content displayed to their users and separate them from the organic search results. However, this browser hijacker acts in the opposite way. As a result, security vendors have started detecting it as PUA.Yessearches and similar.

Additionally, YesSearches seeks redirect victim's searches to third party sites that are typically working on increasing their search rank or visitors' number. While some part of these domains is considered to be safe, the other part should be avoided or at least left when entered. Beware that visiting such domains can end up with useless tools on your computer, e.g. fake optimization tools, rogue anti-spyware apps, etc. Additionally, such sites can locate tech support scams seeking to swindle users' personal data.

Furthermore, this potentially unwanted program is also capable of collecting various information about users. Fortunately, YesSearches does not collect personally identifiable information.[3] However, browser hijacker immediately after infiltration starts tracking and recording:

  • search keywords;
  • visited websites;
  • clicked ads;
  • IP address;
  • location.

YesSearches infiltration

Free software installers might include browser hijacker

The virus usually infiltrates the target system when users download freeware or shareware incorrectly. A security team from[5] reminds that PUPs cannot get into the system by themselves. They need users permission to enter the system, and users give it without even knowing it.

If you have recently downloaded some “safe” freeware from the Internet, then it means you have probably received a bundle with it. Shareware bundling is a method used to spread various potentially unwanted programs, such as questionable add-ons or plug-ins. Developers of the freeware do not warn you what lies behind „standard“ or „default“ installation options.

Most of the computer users rush through installation steps, hastily choose default settings for the installation and click finish. You should always pay attention to freeware installation:

  • Read the Terms and Agreements, as well as Privacy Policy.
  • Use “Custom” or “Advanced” installation settings instead of “Quick” or “Recommended.”
  • Untick all the boxes suggesting to install extra programs,
  • Do not give the authorization to change your homepage.
