How to remove Vosteran Search

There are a seemingly endless number of browser hijackers that want to attack your web browser and push you to a web page that displays adverts for the benefit of the malware distributor. One of those is Vosteran Search, and here, we’ll show you how to remove it. 

What is Vosteran Search?

It’s a type of malware or potentially unwanted program (PUP) that is known as a browser hijacker. These malicious pieces of code change your browser’s homepage and default search engine so that they point towards another site, in this case, Vosteran.com. 

This page, which looks like a harmless search engine, is designed to collect data like your IP address, search queries, and website history and then target you with customized adverts. If you click on an advert, not only will you risk downloading yet more malware, you will be generating revenue for the malware distributor. Is Vosteran a virus? No, but you should still remove it.

How did it get on my Mac?

The most common method is using a technique called "bundling." This is where PUP.are packaged up with legitimate applications that you choose to download. This usually happens when you download software from a site that uses its own proprietary download manager. Often, you don’t even realize you are downloading other software.

The other method is by using pop-up adverts that claim some part of your system is out of date or needs to be repaired. If you click on the link on the advert that claims to offer a fix, you’ll download the malware.

So, to avoid downloading Vosteran Search, or other PUPs:

  1. Don’t download software from sites that use a proprietary download manager.
  2. Don’t click on links on pop-up adverts.

Tip

If you have found malware in Chrome or Firefox, it may have left other files on your Mac that are difficult to find. To make sure you get rid of them, you can reset the application, so it reverts to the state it was in when you first installed it. The easiest way to do that is to use the Uninstaller utility in CleanMyMac X, which allows you to reset applications as well as uninstall them.

Moreover, Vosteran Search displays adverts that make money for the malware distributor. Fortunately, it’s not difficult to remove if you follow the steps above carefully. Don’t forget to scan your Mac for malware once in a while to keep it safe.
