What is virus?

InitialSite123 is is the site that appears set as the default homepage and even search engine redirect virusThis is a potentially unwanted program that can enter the computer unnoticed and start displaying unwanted content to users

InitialSite123 is a browser hijacker that enters users' machines with the help of deceptive distribution methods, primarily software bundling. The unwanted application enters the computer unnoticed and performs several changes to Google Chrome, Internet Explorer, Mozilla Firefox, and Safari, setting the new tab and the homepage address to the questionable site. The PUP then constantly disturbs web browsing settings by displaying alternative search results, displaying excessive advertisements on various domains, redirecting[1] users to suspicious websites, and slowing down the web browser. InitialSite123 should be immediately eliminated once its presence is spotted. To find out how, please follow this article.

InitialSite123 is one of the millions of hijackers that float around the internet and is almost identical to These types of applications never bring any benefits to the end-user and instead might even harm the system and the user. For that reason, threat removal should not be delayed, as, as long as the hijacker remains on the device, personal information and malware infections are real threats.

It would be wrong to call it a virus, as it is not malware. The software is legitimate, although it does use unfair distribution techniques and tries to deceive users with its alleged usefulness. In reality, potentially unwanted programs are created with only one goal in mind: to gain revenue (pay-per-click)[2] from advertisement, all at the infected users' expense.

Unfortunately, some adware or browser hijacking applications can be a real pain to eliminate, as traces might be left on the browser itself, and not the system. Thus, if you are dealing with the removal with no luck, you should know that the easiest and the most effective way to remove it is using reliable anti-malware software, although our guide below is just as effective.

Another downside of InitialSite123 is the constant sponsored links that are shown at the top of the search results. This is as well done in order to make users click on sponsored links and bring partners more visits, which consequently increases the rank of the site.

However, such activity can completely destroy the web browsing experience, as finding relative information becomes almost impossible. The unwanted ads can be eliminated only after you remove the intrusive virus from your computer.

Finally, security experts warn that most potentially unwanted apps collect a variety of anonymous information about its users, which can include, but is not limited to:

  • IP address;
  • ISP;
  • Web search history;
  • Links clicked;
  • Bookmarks added;
  • Cookies, etc.

The aggregated data then allows InitialSite123 developers to create profiles based on browsing habits, in a scheme that is called targeted advertisement. While, when done right, it can be used for benefiting the end-user and the marketing team, the browser hijackers, and other PUP authors may misuse the data. For example, cookies can stay in your browser for up to 10 years, and they can say a lot about you.

As soon as you get rid of the hijacker, we suggest you scan your machine with SpyHunter 5Combo Cleaner, Malwarebytes. This repair software can fix all the damage done that was related to the hijacking of web browsers. virusIf this web page appears in your eyes every time you open Chrome or Mozilla, it means that your browsers were hijacked by the browser-based PUP-type virus.

Protecting your PC from browser hijackers

To avoid browser hijackers, adware-type programs, and similar potentially unwanted software, you need to choose software download sources carefully. We strongly advise you to choose Custom or Advanced, and not Standard or Default installation settings for the setup. These settings will provide you with the list of suggested third-party downloads and allow you to drop them off.

If you don’t manually configure components of your download, remember – all programs bundled with your desired software will be installed without asking you twice[3]. That is the main reason why we do not recommend choosing Standard/Basic/Express/Default settings in software installers.

Such a program should be avoided, because they can unintentionally collect some personally identifiable details about the user, too. To protect your PC from unwanted apps and other shady programs that try to step into the computer system without the user’s permission, we suggest you download a security application that specializes in PUP detection.

How to prevent from getting browser hijacker

Stream videos without limitations, no matter where you are

There are multiple parties that could find out almost anything about you by checking your online activity. While this is highly unlikely, advertisers and tech companies are constantly tracking you online. The first step to privacy should be a secure browser that focuses on tracker reduction to a minimum.

Even if you employ a secure browser, you will not be able to access websites that are restricted due to local government laws or other reasons. In other words, you may not be able to stream Disney+ or US-based Netflix in some countries. To bypass these restrictions, you can employ a powerful Private Internet Access VPN, which provides dedicated servers for torrenting and streaming, not slowing you down in the process.

Data backups are important – recover your lost files

Ransomware is one of the biggest threats to personal data. Once it is executed on a machine, it launches a sophisticated encryption algorithm that locks all your files, although it does not destroy them. The most common misconception is that anti-malware software can return files to their previous states. This is not true, however, and data remains locked after the malicious payload is deleted.

While regular data backups are the only secure method to recover your files after a ransomware attack, tools such as Data Recovery Pro can also be effective and restore at least some of your lost data.
