Type: Browser Hijackers
Common infection symptoms:

Seek123.net is obviously a browser hijacker that will enter your computer unexpectedly. You will probably think that this program is a dangerous virus, but sometimes it is even hard to call it an “infection.” The point is that computer users tend to install such programs on their systems without even realizing it. This happens due to the distribution methods employed by browser hijackers. It might be hard to avoid this intruder sometimes, but you can be sure that there is always a way to remove Seek123.net. If you scroll down to the bottom of this description, you will find the manual removal instructions you can use right now.

This browser hijacker seems to be directly associated with Searchfar.net, Asiasearch.co, Gotsearch.co.uk, Fetchsearch.com, and a number of other browser hijackers we have discussed before. This would imply that the program uses the same distribution methods as its predecessors, although the locations affected by each threat could differ. Nevertheless, users should exercise caution when they open unfamiliar websites because they might as well encounter third-party installers that distribute browser hijackers and other undesirable apps. And this is probably one of the most important things about such intruders: users allow them to enter their computers.

How to avoid installing Seek123.net? First, you should stay away from file-sharing websites. As you can probably tell, this browser hijacker does not have a direct distribution source. If you were to land on its main page, the program would offer to set the domain as your default engine, and there, you would have the chance to decline this offer. However, if the browser hijacker comes bundled with freeware, and you install this freeware on your computer without even bothering to check the steps in the installation wizard, then do not be surprised to find Seek123.net on your browser the next time you access the Internet.

When the program enters your computer, it changes the homepage address on all major browsers. Thus, whether you are using Chrome, Firefox or Internet Explorer, you will be affected by this hijacker. What’s more, the program offers you to download a plug-in from its main page, but the service does not seem to be working. If you click the download plug-in button, on Chrome, you will get a notification that says you need to add the add-on manually. Firefox will not display the download option at all, and the same applies to Internet Explorer and Edge, too.

There are also other options on the homepage, including Make Homepage, Bookmark, and Add Search to Your Site. However, clicking them does not seem to work, either. If anything, the browser settings modification occurs when this program enters your system. So while this program tries to pass for a useful search provider, the truth is that the only reason it is there on your computer is to redirect you to affiliated sites and make some money. And you become a tool in this scheme. A tool that helps the people behind this application become rich.

Not to mention that with Seek123.net installed on your PC, its creators will be able to collect various types of data about you. For example, the hijacker can collect information about your device, the software installed on it, your operating system and your ISP. This information will be obviously used to target custom content at you. This content targeting will probably manifest via modified search results. Therefore, do not be surprised to see more links that will seem related to your likes and preferences. The browser hijacker needs to utilize that in order to generate a financial profit. However, if you fall for this scheme, you may also end up getting infected with malware.

Of course a malware infection that comes via a browser hijacker is the worst-case scenario, but it is always better to be safe than sorry. To protect your computer and your personal information, remove Seek123.net immediately, and then scan your computer with the SpyHunter free scanner to look for other potential threats. If more unwanted programs are found, delete them with the automated security tool.

It is not just about this one program that needs to be removed. You have to think about the future, too. So investing in a reliable security application would probably be your next step after the browser hijacker removal.
