Yahoo Search

Yahoo Search is often used as an Adware virus-like piece of software that you should remove as soon as possible. Having to put up with it is not only annoying but could also be dangerous to your machine. Unwanted advertisements (Ads) as those generated by Yahoo Search are one of the most common causes for infections with more dangerous viruses and they slow down your computer and make your online experience hell.

A typical example of a potentially unwanted program is the Segurazo Antivirus.

How to Remove Yahoo Search?


The Ads created by Yahoo Search can vary in shape, size, and form. They’ll most commonly be pop-ups and banners, but they could also create new pages (filled with Ads) or maybe even turn random words from texts you read into hyperlinks coupled with a pop-up Ad. What they all share is their function and unfortunately, there is absolutely no quality control over what sites they advertise – it’s whoever paid the creator.

If the Internet ads you see online seem to have recently become more annoying than usual and if they follow you around the web instead of staying only on the sites that typically have aggressive advertising activities, then you should consider the possibility of having a browser hijacker such as Yahoo Search on your machine. Or maybe you already know that you have this app on your system and are currently trying to find a way to put an end to the frustrating ads-generation that you are being subjected to each time you try to use your Firefox or Chrome browser (or, really, any other browsing software). Some other unpleasant symptoms that are likely to accompany the ads generation if you do indeed have a hijacker on your computer are sudden redirects to promotional webpages and unknown sites an well as an unwanted browser search engine and homepage modifications or replacements. All of this is typical for apps like Yahoo Search “Virus” and though it isn’t directly threatening or harmful to your machine, it could still hide its risks.

Nevertheless, the good news here is that you aren’t faced with a serious cyber-attack such as one from a Ransomware cryptovirus or a Spyware or a Trojan Horse. Hijackers actually have a low to medium risk level and are mostly not harmful on their own. In fact, some might even offer some form of free function in order to lure the user into keeping them on the system. The problem here is that this would still likely not make up for the ads invasion and, thus, it’s still better to simply eliminate the invasive software. Instructions on how you can quickly take care of the frustration brought on by Yahoo Search “Virus” by uninstalling the app are available in the following removal guide that we advise you to make good use of.

More on the topic of Yahoo Search and other browser hijackers

We said that Yahoo Search is no Ransomware or Trojan virus but we also said that there is still a certain level of risk associated with such an app. The main reason for this lies in its rather aggressive advertising and page-redirecting agenda. You are not advised to interact with any of the commercial materials brought to you by Yahoo Search as they may not be safe or reliable. Of course, there will likely be many legitimate offers but it really only takes for you to interact with the one advert that is unsafe for your PC to get targeted by some anonymous hacker’s malicious virus program. With this in mind, it should be quite obvious why we always advise the readers of our articles to stay alert at all times when there’s a hijacker involved and never tough any of its commercial messages. Again, the removal of such apps is the key to keeping your PC safe. Just remember to also avoid obscure software sources and sketchy online content in general so that you don’t get any more browser hijackers installed on your computer from now on.

Don’t click on the Ads, don’t install anything

Most of the sites advertised on Yahoo Search are fake to some extent or another. Some will try to download other viruses on your computer, others will try to sell you hacked software as legitimate. Others may appear OK until the point you make a purchase and then they steal your credit card number. Not all will be fake of course, but it really isn’t worth the risk so you are best off staying away from those Ads.

Also, Yahoo Search may try to make you install a virus on your computer. It follows the standard scheme of free software installation, which Yahoo Search will go to lengths to make it seems legitimate. For example, Yahoo Search is not shy of creating fake error or warning messages claiming non-existing problems with your computer – stuff like missing plug-ins, required codecs, virus infestations or errors with the registry. You’ll then be prompted to download a program that could fix those, but in reality, you’ll be downloading a virus.

We get asked this a lot, so we are putting it here: Removing parasite manually may take hours and damage your system in the process. We recommend downloading SpyHunter to see if it can detect parasite files for you.

Press CTRL + SHIFT + ESC at the same time and go to the Processes Tab (the “Details” Tab on Win 8 and 10). Try to determine which processes are dangerous. 


Right click on each of them and select Open File Location. Then scan the files with our free online virus scanner:

Drag and Drop Files Here to Scan
Maximum file size: 128MB.

This scanner is free and will always remain free for our website's users. You can find its full-page version at:

After you open their folder, end the processes that are infected, then delete their folders. 

Note: If you are sure something is part of the infection – delete it, even if the scanner doesn’t flag it. No anti-virus program can detect all infections. 


Hold together the Start Key and R. Type appwiz.cpl –> OK.


You are now in the Control Panel. Look for suspicious entries. Uninstall it/them.

Type msconfig in the search field and hit enter. A window will pop-up:


Startup —> Uncheck entries that have “Unknown” as Manufacturer or otherwise look suspicious.


To remove parasite on your own, you may have to meddle with system files and registries. If you were to do this, you need to be extremely careful, because you may damage your system.

If you want to avoid the risk, we recommend downloading SpyHunter
a professional malware removal tool.
