Many web users may mistake FastSearch for some sort of a nefarious computer virus from the ranks of the fearful Ransomware cryptoviruses or the stealthy Trojans Horse infections. However, luckily, if you have detected this piece of software on your PC, there is no need to get panicked. FastSearch is nothing more than an irritating online advertising software tool, which belongs to the browser hijackers family. As a typical representative of this group of software, this application may affect any browser that you may have installed on your system. Chrome, Firefox and Internet Explorer are some of the most commonly affected browsers since they are also some of the most popular ones. However, other browsing programs may also get hijacked and may have their homepage or search engine replaced with some new ones that get imposed by the browser hijacker. Since FastSearch is programmed to advertise, it may start to flood your screen with tons of sponsored ads, pay-per-click links, banners, pop-ups, and aggressive commercials during each browsing session. You may not be able to remove the nagging ads no matter what you do if you still have the nagging and invasive piece of software operating from within your browser. Every time you open your browser, intrusive pop-ups may start disturbing you and may often redirect you to some third-party pages and offers. We cannot say how reliable the content that such software may generate could be. Sometimes, you may find some good deals for yourself, but in other cases you may even land on some shady websites where security hazards may lurk. That’s why it is generally advisable to be cautious if a browser hijacker like FastSearch operates on your system. The creators of such software may greatly benefit from having it on your computer because every time you click on the sponsored commercials and links that it displays, they earn revenue from your clicks and visits.

It is debatable how beneficial the browser hijacker could be for you and if there’s any actual reason for you to keep it on your PC. In most of the cases, such software apps fail to provide any useful functionality which can compensate for the aggressive ads exposure and the overall intrusiveness that they tend to cause. What is more, sometimes (though not purposefully), a hijacker may even expose you to nasty viruses and malware. For this reason, we would suggest that you consider the uninstallation of FastSearch as a solution to your browsing disturbance. Once the hijacker is removed, you won’t be seeing its nagging ads anymore and the likelihood of getting redirected to something suspicious will greatly decrease.

Can FastSearch cause damage to your PC?

FastSearch is not a virus, therefore, it is very unlikely that it will damage your system in any way. Unlike notorious computer threats such as Ransomware or Trojans, which are specifically created to perform cybercrimes, the purpose of the browser hijacker is simply to advertise and to benefit its creators via paid clicks on its ads. It has no malicious code which can corrupt your data or steal your information. Therefore, the security experts do not regard it as highly dangerous software. However, the hijacker can be seen as potentially unwanted and should still be uninstalled due to the reasons described in the first paragraph. What is more, typically, such software can become part of your system in a bit sneaky way, without actually being wanted. It often can be found inside different spam messages, ad-supported sites, free download links and various application bundles. That’s why, when you are installing some new application on your PC, make sure you carefully check for additionally bundled applications by selecting the Advanced/Custom settings and make the necessary changes according to your preferences.

FastSearch Removal


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.

The first thing you need to do is to Quit Safari (if it is opened). If you have trouble closing it normally, you may need to Force Quit Safari:

You can choose the Apple menu and click on Force Quit.

Alternatively you can simultaneously press (the Command key situated next to the space bar), Option (the key right next to it) and Escape (the key located at the upper left corner of your keyboard).

If you have done it right a dialog box titled Force Quit Applications will open up.

In this new dialog window select Safari, then press the Force Quit button, then confirm with Force Quit again.

Close the dialog box/window.



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.
