Yahoo Redirect Virus – How Did I Get It?
This redirect search virus is the type of threat that is very similar to other redirect viruses of it’s kind, for example Google Redirect virus and Bing Redirect virus. All those threats are related to potentially unwanted programs like browser hijackers, adware, and browser extensions.
The primary method of this unwanted app getting in your computer is the installation of software downloaded from third-party sites that are not the official publishers of the program. Programs like media players, torrent download software or any other type of commonly used free apps may be misused for the spread of PUPs that hijack browsers and push the Search virus. The way the unwanted software installs itself on your computer is by being concealed in the installer of the downloaded program as a helper program.
These programs are often included in one of the installation steps of the free program you have downloaded, usually in the “Advanced” or “Custom” setup mode. They are often concealed as “free extras” and prompt you to add them to the current installation. Since most inexperienced users fall for this trick, the Yahoo Search Virus programs are installed silently on your computer system. Here is an example of how such bundled software may appear like on your computer system:
In addition to being bundled with other installers, the redirection software may also install itself automatically as a result of you having malware or other adware previously affecting your computer. Such viruses come in a variety of ways, including visiting malicious websites.
Yahoo Search Virus – What Does It Do?
A good way to describe this browser hijacking software is that it takes advantage of cookies and other tracking technologies which it uses on your computer after it’s installation and execution. These technologies are likely to be:
- Cookies.
- Locally Shared Objects, also known as Flash Cookies.
- Tags.
- Pixels.
- Geo-locators.
Those tracking technologies are used to obtain different information from your computer system. Such info can be:
- Your IP address.
- Nationality and local language.
- Your network information.
- Most visited websites.
- Online searches via the suspicious search engine which is set as your default and redirects results to its own search engine.
- Online clicks.
- Browsing history.
In addition to this, this redirect “virus” may also not use encryption on the suspicious search engine it sets as default for your web browser. This is highly unethical and poses a significant number of security risks to your computer.
Besides this, another reason why this application is considered to be generally unsafe is that it may also “assist” you with your browsing experience by collecting information about your online activity in order to display a lot of advertisements. The ads, displayed by this redirect may significantly slow down the loading speeds of your computer and in addition to this can be different types, such as:
- Browser redirects to third-party websites.
- Ads, which may pop-up directly on your screen and contain audio and animations.
- Taken over banner spaces of the websites you visit, instead of seeing Google Ads.
- Highlighted text on the sites you visit, which displays a pop-up after you hover on it with your mouse.
The advertisements that are displayed by the redirect “virus” may lead you to various suspicious third-party websites, which may be very dangerous to your computer, such as:
- Tech Support scamming sites which fake an infection on your PC to get you to call a number provided, belonging to scammers.
- Infect your computer with malware, such as ransomware, CryptoMiner Trojans and many other viruses.
- Redirect you to fake PayPal, eBay, Amazon or other phishing pages, which may trick you into entering your financial details, passwords and other data, while you are believing you are buying a product from the real websites.
The removal of the undesired program that is redirecting affected browsers to Yahoo Search may be a challenging task. Some of these invasive programs are configured to install the so-called browser helper objects. In Windows systems, malicious browser helper objects may affect the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\.
Once the nasty program has its values there, it becomes able to control the affected browser by redirecting it to this redirect’s web page. So that’s why a simple uninstall process won’t be efficient for the removal of any potentially unwanted programs associated with the appearance of the search virus in your favorite browser. Since the removal of some important and legit registry entries may lead to a total system crash, security experts recommend the help of a Registry Editor cleaner. The tool will locate malicious entries only and remove them without damaging the regular system performance.
