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.

Yessearches.com – Technical Analysis

Upon installation, Yessearches Hijacker creates these files in the following Windows directories:

In %ProgramFiles%\Claqogeheqther\:
In %Windir%\Tasks\:
Claqogeheqther Verfier.job
In %ProgramFiles%\yesbnd\
\dmp\Clqvrftsk.exe Source: Symantec

The Yessearches.com software may also modify various settings of the affected computer, by creating values with custom data and new keys in the Windows Registry Editor:

In HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\

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:

What Is Yessearches?

The Yessearches threat is adware or browser redirect virus.

It may slow your computer down significantly and display advertisements. The main idea is for your information to likely get stolen or more ads to appear on your device.

The creators of such unwanted apps work with pay-per-click schemes to get your computer to visit risky or different types of websites that may generate them funds. This is why they do not even care what types of websites show up on the ads. This makes their unwanted software indirectly risky for your OS.

What Are the Symptoms of Yessearches?

There are several symptoms to look for when this particular threat and also unwanted apps in general are active:

Symptom #1: Your computer may become slow and have poor performance in general.

Symptom #2: You have toolbars, add-ons or extensions on your web browsers that you don't remember adding.

Symptom #3: You see all types of ads, like ad-supported search results, pop-ups and redirects to randomly appear.

Symptom #4: You see installed apps on your Mac running automatically and you do not remember installing them.

Symptom #5: You see suspicious processes running in your Task Manager.

If you see one or more of those symptoms, then security experts recommend that you check your computer for viruses.

What Types of Unwanted Programs Are There?

According to most malware researchers and cyber-security experts, the threats that can currently affect your device can be rogue antivirus software, adware, browser hijackers, clickers, fake optimizers and any forms of PUPs.

What to Do If I Have a "virus" like Yessearches?

With few simple actions. First and foremost, it is imperative that you follow these steps:

Step 1: Find a safe computer and connect it to another network, not the one that your Mac was infected in.

Step 2: Change all of your passwords, starting from your email passwords.

Step 3: Enable two-factor authentication for protection of your important accounts.

Step 4: Call your bank to change your credit card details (secret code, etc.) if you have saved your credit card for online shopping or have done online activities with your card.

Step 5: Make sure to call your ISP (Internet provider or carrier) and ask them to change your IP address.

Step 6: Change your Wi-Fi password.

Step 7: (Optional): Make sure to scan all of the devices connected to your network for viruses and repeat these steps for them if they are affected.

Step 8: Install anti-malware software with real-time protection on every device you have.

Step 9: Try not to download software from sites you know nothing about and stay away from low-reputation websites in general.

If you follow these recommendations, your network and all devices will become significantly more secure against any threats or information invasive software and be virus free and protected in the future too.

How Does Yessearches Work?

Once installed, Yessearches can collect data using trackers. This data is about your web browsing habits, such as the websites you visit and the search terms you use. It is then used to target you with ads or to sell your information to third parties.

Yessearches can also download other malicious software onto your computer, such as viruses and spyware, which can be used to steal your personal information and show risky ads, that may redirect to virus sites or scams.

Is Yessearches Malware?

The truth is that PUPs (adware, browser hijackers) are not viruses, but may be just as dangerous since they may show you and redirect you to malware websites and scam pages.

Many security experts classify potentially unwanted programs as malware. This is because of the unwanted effects that PUPs can cause, such as displaying intrusive ads and collecting user data without the user’s knowledge or consent.
