Cool Web Search

Cool Web Search is a browser-redirecting application that will cover your browser tabs with ads and open new ones in attempts to page-redirect you to promoted sites. Cool Web Search will also manipulate the results of your search engine and replace the starting page address without your approval.

The Cool Web Search virus will redirect you to other web pages

If you have never had a close encounter with a similar application in the past, then you might be afraid that Cool Web Search could damage your computer, steal your data, or corrupt your software. However, the truth about browser-hijacking apps like, Main Captcha Top is that, in most cases, the worst they could do is slow-down the browser (Firefox, Chrome, Edge, Safari, etc.) and cause uncontrolled ad-generation in it that can heavily obstruct your browsing sessions. Even if browser hijacker apps are oftentimes seen as malware, they are different from dangerous and harmful threats like Trojan Horse viruses, Spyware hacker tools, Phishing viruses, or Ransomware. The main goal of a browser hijacker is to get you to click on its ads and visit the sites that it promotes as this earns revenue for the creators of the unwanted app. However, when it comes to actual damaging abilities, most representatives of this software category don’t have any. This is not to say that you should treat Cool Web Search as a perfectly safe app for your browser but, at the very least, there is no need to be overly worried that something bad might happen to your computer.

Why it’s still important to uninstall Cool Web Search ASAP

Security researchers warn users against applications of the browser hijacker category, saying that these apps might still indirectly expose the computer to danger if the user isn’t careful. The problem here are the uncontrolled ads that pop-up on the screen and link the user to all kinds of online addresses, some of which may be potentially unsafe. In many cases, a hijacker may even show you misleading adverts that seem to be promoting one thing but end up redirecting you to a site that offers a totally different type of product. Worse yet, you may eventually end up on a phishing site or on a site that contains disguised Trojans or Ransomware cryptoviruses. Although this is not all that common and it is certainly not the aim of the browser hijacker to expose you to danger, the fact that it is still a real possibility shouldn’t be ignored. 


Obviously, the best way to keep your system safe and to prevent any security issues is to fully uninstall the CoolWebSearch browser hijacker from your computer. However, this is not as easy as it may seem and it may require you to go through some system settings that have been changed by the hijacker and restore them to their normal state before you can remove CoolWebSearch.

The good news is that we can help you here by showing you the exact locations in your system where Cool Web Search has likely left traces of itself so that you can remove them and, by doing so, prevent the undesirable app from coming back to your browser after you remove it.
