Yessearches.com – Means Of Distribution
To be successfully installed on the affected users’ computers, Yessearches uses a very widespread marketing technique – bundling. This involves the including of Yessearches in the installer of another program downloaded by the user. Usually, such “bundled” programs are provided in third-party websites that provide free downloads of different software. Once the user downloads the software, they tend to miss a step, prompting them to add the application as a free extra, for example:
Such steps are usually featured in the “Custom” or “Advanced” installation options and sometimes they are not even featured. Instead, the existence of such applications may be simply mentioned in the EULA agreement for the freeware. Users are advised to take extreme caution in the future and always check thoroughly every installation.

From what it seems these registry entries may allow for Yessearches browser hijacker to have the closest thing to escalated privileges on your computer, changing web browser settings and making other modifications in addition to that as well.
Furthermore, when the website of Yessearches was checked, it was immediately noticed that it aims to resemble a legitimate search engine, but uses other search providers to display its results. However, it is important to know that the search engine uses a high amount of different cookies as well, which is rather unorthodox for search engines, especially when the connection to them is not HTTPS.
Not only this, but the hoax search engine also displays advertisements to various third-party software providers. This is the primary menace associated with Yessearches.com browser hijacker since third-party websites may conceal different dangers to users:
- URLs containing malicious JavaScripts.
- URLs containing Exploit Kits.
- URLs containing Ransomware, Trojans and other malware inserted via drive-by downloads.
- URLs, which may redirect the user to scamming websites which aim to collect financial information, for example, Phishing web pages or tech support scams.
This is the main reason why experts advise removing unwanted ad-supported applications, like Yessearches Browser Hijacker. They may not be malware that directly affects the information, however this hijacker may have the capability to indirectly infect your device. The company even admits the lack of control in their privacy policy:
