How To Eliminate Browser Hijacker

DealWifi by RAFO Technology is another browser hijacker which does not have any value to the user. It takes control of your browser settings and tries to monetize your search and browsing activity.

This adware changes the homepage to, modifies the default search engine and other browser settings. When you search using their engine it actually redirects your queries to a third party provider. It also displays lots of sponsored search results and earns money from your clicks. Since the search page is only designed to earn as much advertisement revenue as possible the quality of search results is low.

DealWifi browser hijacker infiltrates through a vaguely described software which only acts as a gateway to your system. It also places backup programs to prevent removal and stay on the infected computer as long as possible. This is why many users find it very hard to remove.

Use our automatic removal and protection tool to eliminate this unwanted program and prevent similar infections in the future. We have also prepared a manual guide. However, you will still need to secure your system afterwards if you choose this option.

What is browser hijacker?

Technically browser hijackers are not viruses but potentially unwanted programs as they are often installed by the users themselves. Such programs are bundled with other legitimate freeware and infiltrate the system if a user quickly skips through setup process and clicks “Accept”. They often do not have any value and are only designed to earn money from your browsing activity.

DealWifi is no exception as it also displays this parasitic behavior. It is unclear what the software actually does as it says “Enjoy free WiFi from now on” and promises that “DEAL WiFi will make your PC into wireless router and no need to worry about the traffic!“. However, no further explanation is provided, there are many mistakes on the landing page and it is clear that it has been only created so that this fake product would look legitimate.

DealWifi uses many addresses and they often start with “mystart” followed by a number and then domain. For example:

The websites look identical and the different addresses are probably just a way to track different campaigns. Currently most of them are estimated to receive well over 500 000 daily pageviews so we can suspect that many browsers have been infected during the operation of this adware:

Search functionality is powered by a third party marketing company as DealWifi does not have such option. It is said to combine many engines like Google, Yahoo and Bing and provide the best results. However, in reality the search results are full of unwanted advertisements and the quality cannot be trusted.

Only changing the browser settings or deleting browser extensions does not help as in most cases the hijacker comes back. This is because it has backup program installed which makes sure that no changes were made to the settings.

Having such browser hijacker installed on your system is dangerous since it can track your personal information. Unwanted programs also often lead to more infections as they tend to redirect to suspicious links, offer additional software and extensions and display infected advertisements.

You should follow our removal guide in order to restore normal browsing experience and protect your computer from spying. We recommend using the automatic removal tool as it will also act as an antivirus in the future. However, a manual guide is available as well.

 Manual Removal Instructions:

NB: Make sure you are familiar with editing important Windows settings and files. In order to not only remove the symptoms but also any possible leftovers of the adware we recommend using the automatic tool provided above.

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. If you have never seen or used an app chances are that it is an unwanted software.

Usually the unwanted program uses the following name:

DealWifi(Deal Wifi Hotspot) by RAFO TECHNOLOGY INC

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

Repeat this process until no more suspicious programs are left.

Step 2:

Delete registry values created by this adware.

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

Enter the following in the field:


Click OK.


Search for virus entries by pressing keyboard buttons CTRL + F and entering the virus domain. 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.

Step 4:

Remove suspicious programs from your startup config so they would not launch as soon as you boot your computer.

Hold Windows () key and click R key.

Enter the following in the field:


Click OK.

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

You will see locations of the files in “Command” column. Navigate to the location and delete it if a suspicious file is found.

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:

IMPORTANT: Now you will have to reset browser settings for each browser individually that you have installed on your computer. Alternativelly, you could simply reinstall them.

The unwanted addons are usually named similarly to the program you have just uninstalled using Add or Remove Programs.

 Google Chrome:

Launch the browser and select More Tools, then click Extensions.

Check for any suspicious extensions.

Click Remove From Chrome for each unwanted or suspicious toolbar or extension (the trashcan icon on the right).

Go to Settings.

Scroll to the very bottom of the settings page and click Show advanced settings…

Scroll to the very bottom again and click Reset settings.

Click Reset.

 Mozilla Firefox:

Launch the browser and go to Add-ons.

Search for any suspicious toolbars and add-ons and Remove them.

We recommend going to Options (input about:preferences in your address field and press Enter) and clicking Restore to Default near the Home Page field.

You can also completely refresh the browser settings by entering the following in the address (URL) field:


Press Enter.

Click Refresh Firefox… and then click Refresh Firefox again.

 Microsoft Edge:

Since Microsoft Edge is not a separate program and is a core component of Windows 10 you should backup your computer or at least create a Restore Point before continuing.

Navigate to the following folder (where %username is your computer user name):


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

Click Start (Windows logo).

Search for Windows PowerShell.

Right-click on the result.

Choose Run as administrator.

Paste the following command:

Get-AppXPackage -AllUsers -Name Microsoft.MicrosoftEdge | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register $($_.InstallLocation)\AppXManifest.xml -Verbose}

Press Enter.

The settings should now be reset to default.

 Internet Explorer:

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

Enter the following in the field:


Click OK.

Enter the following command in the appeared window:

RunDll32.exe InetCpl.cpl,ResetIEtoDefaults

Press Enter.

Check Delete personal settings.

Click Reset.

Alternatively you can run this command to delete all caches and settings:

RunDll32.exe InetCpl.cpl,ClearMyTracksByProcess 4351

After removing the virus

When you have finished removing the “DealWifi” 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.
