What is browser hijacker?

Technically most browser hijackers are not viruses, but potentially unwanted programs as they are often installed with user’s consent. However, usually their distribution methods are unethical and aimed at infiltrating the computer at any price instead of offering real value to the user. This is why most browser hijackers are bundled with other free software (usually hidden deeply in the setup process) and get installed automatically as soon as you click “Accept”. In many cases this happens accidentally since the setup steps could be unclear and designed to trick users into accidentally allowing the adware to enter their system.

It is much harder to remove browser hijackers once they get installed than to prevent them. It is because most of them take control of your browser settings by launching background programs and hijacking program shortcuts. This is why many users get confused and decide to give up on trying to eliminate this unwanted program. Others might even think that it is a legitimate browser component since it is impossible to remove.

The website states the following: utilizes metasearch technology to compile results from many of the Web's major search properties, 
delivering more relevant and comprehensive results every time you search.

In reality it does not have such functionality and simply redirects your search queries. Search engines like Yahoo or Google are used directly instead of providing own results or combining them.

The only purpose of is to earn revenue for its creators by utilizing the traffic from infected browsers. The website displays sponsored search results, banner advertisements and hidden affiliate links. It might also redirect you to other pages and suggest installing additional software or browser extensions. This could litter your computer with more adware or even lead to other more serious infections.

Another risk of having present on your system is being spied on. All your search queries go through this website and it might record your browsing activity and use it for marketing purposes or sell to other parties. This is why you should remove it as soon as possible and restore normal browsing experience as well as increase system speed.

We recommend using the automatic tool provided above which is the easiest option to remove this and any other threat present on your system. It will also protect your computer in the future by acting as a full antivirus solution. We also have a manual removal guide for experienced Windows users. However, this method does not guarantee protection in the future.

Bookmark this page, print it out or simply open on another device in order to access it after a browser or computer restart which will be required during the removal process.

Step 1:

Remove any suspicious programs that might contain the adware.

Start by opening the Programs and Features window using the following method:

Hold Windows () key and click R key while holding.

Enter the following in the field:


Click OK.

You might have to wait a bit before the list of all programs is loaded as it displays a list of all programs installed on your PC.

We recommend sorting the programs by “Installed On” column (simply click on the column name in order to sort by this value).

Look for any recently installed suspicious programs that might contain the adware as a bundle or could be the adware itself. Such programs also have the word “search” in their name. If you have never seen or used an app chances are that it is an unwanted software.

Example of a program name:


Uninstall all suspicious programs by right-clicking on them and choosing Uninstall…

Repeat this process until no more suspicious programs are left.

Delete registry values created by this adware.

Press and hold Windows () key and click R key.

Enter the following in the field:

Search for virus entries by pressing keyboard buttons CTRL + F and entering the virus name. Here is an example:


Click Find Next.

Delete any registry entries associated with the virus.

Repeat the search until all entries are cleaned.

Step 3:

Clean up Windows temporary files.

You can safely remove all temporary files without posing any risk to your computer.

Hold Windows () key and click R key.

Enter the following in the field:


Click OK.

All temporary files will be listed in the directory.

Select all temporary files by simultaneously pressing CTRL + A and delete them.

Go to the Startup tab and uncheck all suspicious entries. Look specifically for “Mysites123” as well as other similar programs.

If you are unsure you can simply leave it unselected but not delete it.

Click OK when you are finished unselecting and deleting all potentially dangerous processes.

Step 5:

Delete the shortcuts for all browsers on your computer as they might have been changed by the hijacker.

Remember that there are shortcuts not only on your Desktop but also in other places (for example, Start Menu).

Then create them again in order to have clean browser start.

Alternatively, you can click Properties on each of the shortcuts and remove any additions made to the Target field by the adware.

Step 6:

Clear all contents of the folder. Click CTRL + A to select everything and delete the contents.

Click Start (Windows logo).

Search for Windows PowerShell.

After removing the virus

When you have finished removing the “Mysites123” adware and reverting your browser settings make sure to protect your computer by installing a good antivirus suite that would identify the threats online and in programs you have downloaded. Also, never install suspicious programs. If you are installing a new software, make sure it has nothing bundled in it by following the install wizard as well as searching for user reviews online.
