Annoying ads, banners and pop-ups all over your screen? might be the program that is generating them. Other visible symptoms that could give the presence of this program away may be related to the sudden change in the browser’s homepage, or to the replacement of your default search engine with another one, which constantly initiates sponsored page-redirects. The common term that describes this type of behavior, and is used to classify programs of this type, is Browser Hijackers. In the next paragraphs, you will learn more about the nature of the Browser Hijackers and their typical symptoms, as well as about the methods you could use to effectively deal with, and with the changes it has imposed on your Safari, Chrome, Firefox or any other main browser. In fact, below you will find a detailed removal guide and a professional removal tool, both of which can help you quickly remove unwelcome browser add-ons, such as the one that we are talking about right now.

Can the Virus be a danger to your computer? Virus

The Virus will redirect your searches and display Pop-up ads.

The initial reaction of most people who encounter the nuisance of Browser Hijackers is usually the same – they think that their computer might have been infected with a strange redirect virus or with some unfamiliar malware piece similar to Ransomware or Trojans. Luckily, this is not the case with Browser Hijackers. Those programs are much different than the computer viruses you fear of since they are typically incapable of causing system damage, corruption of files, or other destructive issues. Their main activity is related to online advertising and, for as long as they operate on your computer, most Browser Hijackers will only spam you with different sponsored ads, pay-per-click messages, pop-ups, banners, and redirects to predefined web pages. A real virus, on the other hand, is a threat that would do much more than simply spam your screen with commercials. For instance, a Ransomware infection can not only sneak in the system without any visible symptoms, but it can render your files inaccessible until you pay a ransom for them. A program like is far less problematic and will never do such a thing, even if it tends to be extremely annoying and unpleasant to have in your browsing program.

Not being a direct security threat, however, does not mean that the Browser Hijacker should remain on the system. Such software may still create a lot of disturbance not only in your web browsing experience, but also in the system’s performance. Apps like Wysasys.comBing Redirect or Search Baron for instance, may be very intrusive in their attempts to make you click on certain ads and sponsored links. They may literally flood your screen with colorful pop-ups, banners, and clickbait boxes that just won’t stop showing in your browser. Sometimes, they may not even wait for you to click on something but may automatically redirect your web searches to some predefined pages, again, with the goal of to landing you on some promotional message. Therefore, we usually advise our readers to uninstall programs like, and uninstall their changes as soon as possible. You can do that with the help of the instructions in the removal guide below.


Type Browser Hijacker
Danger Level Medium (nowhere near threats like Ransomware, but still a security risk)
Symptoms Intrusive ads, automatic page-redirects, and banners all over the screen are some of the symptoms of Browser Hijackers.
Distribution Method Software bundles, free downloads, automatic installers, ads, torrents, shareware sites, freeware platforms, spam.
Detection Tool Virus 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.

On the off chance that you are still having trouble with scripts interrupting the closing of unwanted pages in Safari, you may need to take some additional measures.

First, Force Quit Safari again.

Now if you are using a Wi-Fi connection turn it off by selecting Wi-Fi off in you Mac’s Menu. If you are using a cable internet (Ethernet connection), disconnect the Ethernet cable.


Re-Launch Safari but don’t forget to press and hold the Shift button while doing it, so no previous pages can be opened up. Now, Click on Preferences in the Safari menu,

and then again on the Extensions tab,

Select and Uninstall any extensions that you don’t recognize by clicking on the Uninstall button. If you are not sure and don’t want to take any risks you can safely uninstall all extensions, none are required for normal system operation.

The threat has likely infected all of your browsers. The instructions below need to be applied for all browsers you are using.

Again select Preferences in the Safari Menu, but this time click on the Privacy tab,

Now click on Remove All Website Data, confirm with Remove Now. Keep in mind that after you do this all stored website data will be deleted. You will need to sign-in again for all websites that require any form of authentication.
