Adware Internet Cyber Attack

How to Remove WebAssistSearch From Mac in 3 Steps

It is extremely frustrating when you open your browser to visit a website or do some search, then you’re redirected to an unknown web page full of ads. If this happens to you every time, then you probably have a browser hijacker on your computer.

Browser hijackers are also classified as adware because the end result is that you get bombarded with annoying ads. There were created to generate traffic and clicks for the clients who are paying them to deliver the sponsored content. You’ll see all kinds of pop-ups, text ads, banners, and other types of advertisements.

There are several types of adware/browser hijacker, and they are usually named after the website used for the redirection or the toolbar installed on the browser. In the case of WebAssistSearch on Mac, the extension is added on the affected computer’s browser and facilitates the operation of the potentially unwanted program.

So if you see the WebAssistSearch on your Mac, then you need to remove it immediately from your device to prevent serious privacy and security issues.

What is WebAssistSearch on Mac?

WebAssistSearch is a common threat categorized as adware, thanks to the shady commercial content it delivers and other questionable activities the malware does in the background.

WebAssistSearch is a malicious program, also known as a potentially unwanted program (PUP) or potentially unwanted application (PUA) that mainly affects macOS devices. The most obvious signs that will alert you to the presence of this malware is the frequent redirects and the unnatural number of advertising materials. So aside from being considered adware and a PUP/PUA, WebAssistSearch is also categorized as a browser hijacker because of the way it operates.

This malicious app displays intrusive sponsored materials, triggers redirects, and collects your personal data, so you will experience a drop in speed and performance. WebAssistSearch is not totally malicious or harmful for your Mac’s operating system since its operation only involves showing ads and redirecting your traffic to other websites.

Its real danger lies in its capability to send you to various URLs in a bid to generate more traffic for its clients. It might redirect you to a page with NSFW content or a website that can trigger the installation of another, more dangerous malware. So if your Mac has WebAssistSearch adware, you need to remove it from your system as soon as you can.

How WebAssistSearch on Mac Gets Distributed

Browser hijackers, such as WebAssistSearch, can be distributed through various means. One of the more popular methods of distribution is through app bundling. If you’ve recently installed a freeware, like a YouTube downloader, file manager, video converter, or other free utilities online, then that’s probably how you got the malware. These free utilities earn by including other software in their installer package, and if you’re not careful with your installations, you could easily install the malicious software, along with the freeware, on your computer.

If you don’t remember installing anything recently, then the malware should have been installed sneakily using other means. Pop up messages that prompt you to update your Flash or other software can also be carriers of this browser hijacker. When you click on the notification, it triggers the download of the malicious script that is injected into your browser’s code. WebAssistSearch can also come from clicking links or downloading mysterious attachments from spam emails without scanning them first. It is also possible that you unknowingly visited a website that hosts malvertising, and the malicious script was stealthily downloaded to your device.

No matter what method the WebAssistSearch adware used to infiltrate your Mac, it doesn’t change the fact that this malware can bring you harm and should be dealt with immediately. Let’s look at what this malware can do in the next section.

What Does WebAssistSearch on Mac Do?

WebAssistSearch mainly delivers intrusive advertising campaigns. You’ll see various pop-ups, coupons, banners, surveys, and other ads marked with Ads by WebAssistSearch. So if you see this note on the ads, then that’s a sure sign that you’ve got malware on your system. These activities severely affect the browsing experience, because they overlay webpage content, use your computer’s resources, and limit browsing speed.

Moreover, clicking these advertisements will redirect you to untrustworthy or malicious websites that execute scripts to sneakily download/install other malware. Browser hijackers, such as WebAssistSearch, also operate by setting the URL of fake web searchers as the browsers’ homepage, default search engine, and new tab or window URLs. In the case of WebAssistSearch, the homepage and new tab page are changed to safefinder.com. When you do a search query, the request is redirected first to safefinder.com before pulling up results from the Yahoo search engine. Every browser activity will be redirected to the said website.

Because of this, safefinder.com is considered a fake search engine that provides no real value to users. It is unable to provide actual search results, so it simply redirects or causes redirection chains leading to a legitimate search engine, which is Yahoo.

What is more frustrating is that it is impossible to undo the changes to the affected browser without getting rid of the browser hijacker first. No matter how many times you try to change back the homepage or reset the default search engine, everything goes back to the same URL that the malware assigned. The malware uses a script to automatically reset any changes that you make to the browser’s settings.

Most browser hijackers also have data tracking abilities that allow them to understand the user’s preferences better and deliver more targeted ads. WebAssistSearch on Mac can monitor all your browsing activities, including the websites you visited and the queries you made. It can also collect your personal data, such as your IP address, email address, geolocations, credit card information, your birthday, passwords, and other information you typed in online. Typically, the collected data is used to personalize the ads being displayed on your screen. However, it is also possible that the gathered data is shared with third parties seeking to use it for profit.

WebAssistSearch works just like other browser redirects, including My Sweeps Tab Browser Hijacker, Searchmine Browser Hijacker, GameSearch Browser Extension, and CreativeSearch Browser Hijacker.

At the end of the day, the presence of WebAssistSearch on your Mac can lead to further system infections, some serious privacy issues, financial troubles, and even identity theft. To protect your data and privacy, all malicious applications and browser extensions should be removed without delay.
