With new waves of unwanted applications coming out every week it is important to understand it and know how to prevent it from reaching your PC. Most people seem to be confused when talking about malware. It is a collective term used to describe any kind of software that is used for malicious purposes, hence the name. While the name Virus also belongs to the malware “family”, it is not the only one. Within this article, we shall educate you on the topic of Browser Redirects, why it is often described as malware and why ChumSearch isn’t actually a virus. Before you jump into the removal instructions, please read over the following paragraphs. It’s always a good idea to learn anything you can about the troubles you could be facing when dealing with these dangerous pieces of software. While Browser Redirects are inherently a lot less dangerous than a Virus can be, it also isn’t something to be treated as a pushover, because it certainly isn’t.

What is ChumSearch? What is a Browser Redirect?

Everything first started when software developers started adding freeware (free programs) in popular installers in an attempt to promote themselves. Unfortunately, some people took that advantage and began using these same channels to spread a different kind of software. One which upon entry into a system, spreads uninvited ads to the browsers currently installed such as Chrome or Firefox. It then uses various ways to display them on the browser window. One of them are banners aligned at the sides of the page. While not as restrictive as some of the rest, they are usually rather large and unappealing. The next one is the much more obstructive pop-up ad. It can hide everything you’ve been currently viewing and instead show you a big window front and center which is really annoying to the average user. Last, but certainly not least, are the in-text ads. They are integrated into the text itself that you are reading and are linked to other locations on the web that are dangerous to visit. They can even display pop-up ads if you hover over them. How annoying!

In addition to that, we have yet to talk about the dangerous part of ChumSearch. While the ads may not seem like something to worry about, what happens after you click on them is another matter on its own. Firstly, they are all linked to web pages that can introduce similar programs that can further bloat your Mac, but they can even mislead you into installing dangerous programs or maybe even viruses. Not only that, but clicking on the ads themselves benefits the creators of ChumSearch. A thing called pay-per-click advertising model is one of the most major ways for companies to promote their services and products and also pay the places where they are allowed to position their ads. You’ve probably already guessed at this point that this has something to do with the ads displayed by ChumSearch, and you’d be right. Software developers like the ones that made this same Browser Redirects benefit from the same advertising model. Every time you click on one of the ads you are not only lead to somewhere where you don’t belong, but you also earn money for the attackers of your PC.

Probably the worst part of this whole ordeal is the fact that this software can also steal browsing information and use it against you. When they are in your machine, they collect information such as browsing history (which includes every place you’ve ever visited) as well as search queries (everything you’ve ever searched for). They use these to figure out your interests and use them against you by customizing the ads to your liking. Do not be deceived! You have no benefit from them and they are only used to fool you. It’s nothing but empty promises.

This concludes our short summary on the subject. Do remember that uninstalling or removing ChumSearch can not only seem daunting at first, but it’s really not. If you want to take the easy route download the recommended removal tool, otherwise the manual removal instructions await you!

Remove ChumSearch 


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.
