StreamTopSearch browser hijacker (virus) - Free Guide

What is StreamTopSearch browser hijacker?

StreamTopSearch can be a reason why your browser has been acting strangely

StreamTopSearch may have a fun design but it is not a trustworthy app

StreamTopSearch is a useless browser extension that changes the main settings. It sets the homepage address as portal.streamtopsearch.com and redirects users' search queries through feed.streamtopsearch.com. It also promotes various search engines – fake and legitimate. If you enter a search you may be redirected to one of these engines:

• Yahoo
• Bing
• Searchlee
• Nearbyme

Even though Yahoo and Bing are well-known search engines, the other ones are not. They may present false information and produce inaccurate results or even lead users to dangerous websites. By being redirected to scam pages, people may be tricked into providing personal information to unsecure sources, downloading PUPs, (potentially unwanted programs),^[1] and even malware.

StreamTopSearch in detail

StreamTopSearch is one of many browser hijackers that look very similar. We previously wrote about apps, like QuickPDFConverterSearch, BestMapSearch, and BestSportSearch. All of their names imply that they provide some kind of function. In reality, most of the promised functions are not operational.

All of the plugins that belong to this hijacker family have the same layout, similar names, logo style, and supposed functions – a PDF file converter, calculator, currency converter, and the ability to bookmark pages. There is no reason to keep this extension installed as all of these actions can be accessed with a click of a button on almost every default browser.

Distribution methods

Often people infect their browsers with hijackers by browsing through shady pages. This includes bogus download pages, like Alternatesearches.com, and illegal streaming platforms, like Fmovies. There might be other types of scam pages that use social engineering^[2] methods to trick users into downloading bogus apps.

Hijackers are also commonly spread by freeware^[3] distribution platforms. They include additional programs in the installers to monetize user activity. Most people skip through the installation steps and do not notice the bundled software.^[4] It is important to be very careful during such procedures.

Always choose the “Custom” or “Advanced” installation methods, read the Privacy Policy and Terms of Use to find out what the app will be able to do on your machine. The most important part is to check the file list and untick the boxes next to any unrelated programs.

User privacy and security concerns

StreamTopSearch can damage users' privacy and security

Browser plugins are capable of using cookies to track user browsing activities. These are small data files that can store information such as your IP address, geolocation, websites you visit, links you click on, and things you purchase online. Normally, this information is used to personalize the user experience, however, crooks can sell it to advertising networks and other third parties.

That is why security experts recommend clearing the browsers regularly. This task can be automated with a maintenance tool like RestoroIntego. Besides, it can also fix various system errors, BSODs,^[5] corrupted files, and registry issues which is especially helpful after a virus infection.

How to remove a browser hijacker?

The first thing you should do is go to your browser settings and check if you see StreamTopSearch in the list, any extensions with a similar name, or suspicious-looking add-ons in general. You can follow our guide if you need help:

Scan your system with anti-malware tools

The hijacking could have been caused not only by a browser extension but also by a PUP. If the previous removal method did not get rid of unwanted symptoms, this step should fix it. Adware usually hides in the background of the machine performing unwanted tasks sneakily. Many users do not know about the infection until they start experiencing unpleasant symptoms.

Identifying the program responsible for hijacking your browser might be difficult if you have never done this before. It could be disguised as an antivirus suite, image editing software, media player, system optimizer, or anything else. PUA developers often disguise their products as handy tools so that users would not suspect them of any harm.

If you are not sure what to do and you do not want to risk eliminating the wrong files, we suggest using SpyHunter 5Combo Cleaner or Malwarebytes security tools that will scan your machine, eliminate it, and prevent such infections in the future by giving you a warning before a malicious program can make any changes.
