How does it happen?
There are two common ways of how browser hijackers may integrate themselves with your
browser – either legally or illegally. The first method calls for a user’s participation in the
installation process of browser hijackers. Users are directly notified about installation of a special
program of browser add- on. It is clearly stated by the program that in case of installing such
application the search engine will be modified, the default start page will be amended and replaced
with a new one (depending on the name of browser hijacker). As a result of such installation
authorized by user, a new add- on is installed, resulting search redirections through a new window
that has certain web address, instead of the default blank page of your browser.
In many cases browser hijackers come into computers without a user’s permission. It is generally

brought into your system by malware through application of certain browser vulnerabilities
available. The installation procedure is hidden from user’s attention. Sometimes, the user is
unaware of the unauthorized installation.
Tips & Tricks
Lists of recommended steps to fix browser redirection problem:
Remove all adware, browser hijackers and other unwanted programs through the Control Panel
of your computer.
Scan your system with powerful antivirus program.
Check the Local Area Network (LAN) settings of your system.
Check if DNS settings have been amended by browser hijacker.
Check browser add- ons. Remove all unknown or suspicions add- ons detected (enabled).

Consider running adware- cleaning applications.
Restoring desktop shortcuts of hijacked browsers.
Reset your Router to the factory default settings.
1. Remove adware and browser hijackers through the Control Panel of your PC:
It is of primary importance to first get rid of all adware programs and browser hijackers through
Add/Remove Programs section of your Control Panel (when using Windows XP), or through
Uninstall a program section of Control Panel in Windows Vista, Windows 7 and Windows 8). For this
purpose please refer to the Start Menu. Choose Control Panel, and then go to Add/Remove
Programs. Likewise, when using Windows Vista, Windows 7 or Windows 8, select Control Panel and
2. choose Uninstall a Program.
Now, with Windows 8 things are a little bit different. What you should do is just direct the mouse
pointer to the right corner of the screen, and then select Search from the list, and search for
In the respective section of Search window, type “Control Panel“, and you will see the search
results as follows:
So, after you’ve opened the sections Add/Remove or Uninstall a Program, carefully browse through
the contents of presently installed applications and get rid of particular adware or browser hijacker,
toolbar, search bar or anything else that has the name similar to that site through which your
browser redirects your search. Keep in mind that if such program is in the list of installed programs,
then it appeared there because of your direct participation in its installation process. You may
actually click “Installed programs” and even sorts these installed applications by date. When you
find anything suspicious that might cause browser redirection, select this application and click
Remove. When using Windows Vista, Windows 7 or Windows 8, choose Uninstall in the upper part of
the window. Once the program is successfully removed make sure you close the Control Panel
2. The next step is to scan with effective malware removal tools like Malwarebytes‘ Anti- Malware,
Bullguard, Kaspersky Lab, BitDefender, Webroot, etc.
3. Check the Local Area Network (LAN) settings:
Go to “Start” Menu and again select “Control Panel“.
3. Choose “Network and Internet“.
Choose “Internet Options“.
Go to “Connections” tab, afterwards click “LAN settings” button.
Remove (uncheck) the checkbox under “Proxy server” option and click OK.
4. 4 . Check DNS settings:
Go to “Start” Menu and refer to “Control Panel“.
Choose “Network and Internet“.
Go to “Network and Sharing Center”.
Select “Local Area Connection”.
5. Choose “Internet Protocol Version 6 (TCP/IP V6)” and select “Properties”.
Select “Obtain DNS server address automatically” and click OK.
5. Check browser add- ons:
6. Go to “Start” Menu and direct your mouse pointer towards “Control Panel“.
Choose “Network and Internet“.
In the section “Internet Options” choose “Manage browser add- ons“.
Get rid of any unknown or suspicious Toolbars or Search Providers.
7. 6. Check Windows HOSTS file contents:
Go to: C:WINDOWSsystem32driversetc.
Double- click “hosts” file to open it. Select the option to open it using Notepad.
The “hosts” file must look the same as in the image below. There should be just one line: 127.0.0.1
localhost in Windows XP and 127.0.0.1 localhost ::1 in Windows Vista/Seven. If there are more, then
remove them and apply changes.
Important! You may also choose the feature to reset your HOSTS file using the Tool of GridinSoft
Trojan Killer as shown at the image below:
7. Scan with Kaspersky’s TDSS Killer (free application):
Wait for the scan and disinfection process to be completed. Shut down all applications and hit “Y”
key to reboot your system.
8. 8. Use CCleaner:
CCleaner is the application that can be easily googled and thus downloaded. When running it, keep
in mind that it will clean the entire “Temp” directory of your computer, so if you have anything
important in it please first save the data you need into other locations.
9. Run adware- cleaning applications:
This option is also recommended. There are many working and effective automatic solutions that
might be helpful to you when dealing with browser redirection issues.
10. Clean shortcuts of browsers that have been hijacked:
This step applies only to certain browser hijackers which are extremely severe. However, it is
strongly recommended that you perform this important step. So, search for your browser
shortcut depending on where it is located – on Desktop, in Taskbar or in Start Menu. Now, rightclick it and select Properties:
Click Shortcut tab and get rid of any name of the site through which search redirection occurs
from the Target field and click OK to apply changes. Generally, there should be only the path to the
executable file of your browser, nothing else. See how this is represented on the example of
Google Chrome browser:
9. 11. Reset Router to factory default settings:
At this point we should emphasize that resetting the router to the factory default settings is the
option to which you should adhere only if other tricks above didn’t work. So, this recommendation
should only be followed if in spite of all the above- mentioned recommendations you still have the
redirect virus on your machine. Then you should flush DNS cache:
Click “Start” and in the open space write down “run” This surely applies to Windows Vista and
Windows 7 operating systems. With Windows XP you may fine “Run…” once you click “Start” menu
option. With Windows 8 you may direct your mouse pointer towards the right section of your
desktop until the menu comes up with “Search” tab. This is where you may look for Run command.
Type “cmd” without quotation marks.
In a new window please type “ipconfig /flushdns” without quotation marks and press Enter.
By following the above steps, you will be able to completely remove “Browser Hijack” Virus from
your internet browser. If you still experience issues, contact online Virus Removal service like
Jupiter Support, who will guide you through the removal of the virus at a low cost of only $29.
