Odestech  is an unwanted app that constantly forces your browser to show page-redirect banners, pop-ups, and ads on your screen and introduce a new search engine tool to the browser. Apps like Odestech are typically referred to as browser hijackers.


 Another typical symptoms you may expect from a piece software like this is the replacement of the addresses of your browser’s starting page and new-tab page. Here, our main goal is to inform our readers about a hijacker app called Odestech – it is a pesky software piece and though it may not actually harm the system of your PC, you would certainly prefer to have it eliminated from your Chrome, Safari, Firefox or another browsing program to which it may have been added.

The Odestech Virus

A key thing to remember about most representatives of the hijacker category, like the Odestech virus is that they will probably not allow you to simply restore the previous settings of your browser. Any changes made to your browsing software by the Odestech virus are there to stay.

Unless the invasive app gets removed, your browser would most certainly keep on spamming your screen with various types of ads and would retain its new search engine, toolbar buttons and new-tab and homepage addresses.

And to make the matters even worse, there would usually be no way of simply uninstalling an app like Odestech through any regular means. Most normal programs tend to have an uninstallation manager that allows the users to quickly and easily uninstall them, should they decide that this is what they want. However, a hijacker would stick to your browser for as long as possible, not letting you remove it the easy way. That being said, here we aren’t talking about an insidious Ransomware encryption-virus or some harmful and malicious Trojan, so even if it may be a bit tricky to eliminate Odestech and Captcha Cool Now, you should still be able to manage to remove it without any major negative consequences for the safety of your machine and files.

The purpose and distribution methods of hijacker apps

Obviously, these are tools that are used for some form of online marketing – they spam you with ads and thus increase the popularity of certain sites and improve the chances that the advertised products get purchased by more people. Of course, you don’t really gain much benefit from this. Instead, you are left to put up with the newly imposed (and rather unpleasant) changes in your browser as well as with the constant spam with nagging ads.

To ensure you don’t encounter such software in the future, be careful with the programs you install and always look at their custom setup settings before actually installing them. Most hijacker get added in the setup files of other programs and apps and this is their typical distribution method. It is important that you get rid of Odestech and that you don’t let any more hijackers enter your system or else, you may risk getting your computer compromised by virus infections and malware programs of the Ransomware, Trojan Horse and of the Spyware category since some of the hijacker-generated adverts may not be safe and expose you to danger.

Remove Odestech Virus

To remove Odestech, one needs to clean all browsers in the computer from unwanted add-ons and temporary data that may hold records of the hijacker.

  1. First, go to the main browser’s Add-ons settings.
  2. On that page, find and delete anything that you consider to be potentially unwanted.
  3. Then clean all browsing data (cookies, cached files, etc).
  4. To remove Odestech, repeat the previous 3 steps for every browser that’s in the system.

If this doesn’t do the job and the hijacker is still on your PC, then you’d have to complete several other steps to make sure that your system is clean.

Step 1

*Source of claim SH can remove it.

Start by going to the Control Panel (search for it in the Start Menu) and then opening the Uninstall a Program window. Your task is to find any questionable programs (especially ones installed a little before the hijacker’s appearance in the system) and uninstall them.

If there is a program you think could have anything to do with the presence of Odestech on your PC, click on its name in the Uninstall a Program list and then select the button labelled Uninstall from the top. Complete the following uninstallation process as shown in the uninstallation wizard and make sure that everything related to the potentially rogue program gets removed.

Step 2


*Source of claim SH can remove it.

Open the Task Manager tool using the Ctrl + Shift + Esc key combination and then click the Processes tab from the top. Since the process of the hijacker would probably be consuming lots of memory and processor power, sort the list of processes by the amount that they consume of either resource and then look at the ones that have the highest consumption.

If any of those most resource-intensive processes seem odd, unusual, or unfamiliar, try to find some more information about them on the Internet or tell us what their names are down in the comments. If it turns out that the suspected process (or processes) may be dangerous, go to its File Location folder by right-clicking on the process and selecting the first option.

Whatever files are shown in the newly-opened folder, scan them with the free online scanner we’ve shared right below.

    Task Manager1

    If there’s malicious code that gets detected in any of the files, this means that you should quit the process, so right-click it again and select the End option.

    Next, dispose of all related data by deleting everything in the location folder. In case one or more of the files there can’t be deleted, leave them for the end of the guide. When all other steps have been completed, simply delete the entire location folder of the rogue process.

    Important!: Even if no malicious code was found within any of the files that you scanned, if you have enough reasons to believe the suspected process is malicious, be sure to end it and to eliminate its data.

    Task Manager2

    Step 3 Now get your PC into Safe Mode so as to stop Odestech from starting any of its processes all over again.

    Step 4 Search for “Run” in the Start Menu search box, select the first icon shown in the search results, and type ncpa.cpl in the window that opens. Press Enter or select OK to go to the specified system settings window. When a window with network icons in it appears, right-click on the icon that doesn’t have an X in it – this should be the network that you are currently connected to. Open the Properties of the network, select Internet Protocol Version 4 from the items list, and go to Properties again. In the next window, make sure that the following two options are enabled and then go to Advanced:

    • Obtain an IP address automatically
    • Obtain DNS server address automatically

    In Advanced, open the DNS section, delete anything that may be listed under DNS server addresses, and then click OK in every window.


    After that, return to Run, type in it msconfig, select the OK button, and open Startup in the next window. The items you will see there are the programs, serves, and apps that start automatically every time your computer bots up. Those items should typically be familiar to you, so if any of them looks odd, unknown, or suspicious, you should uncheck it. Once ever questionable item has been deselected, click on OK.


    Finally, type this “notepad %windir%/system32/Drivers/etc/host” in Run, hit Enter and copy all text in the newly-opened file (named Hosts) that’s written below the Localhost word. If there’s no text below that word, this means the hijacker hasn’t tampered with the Hosts file and there’s nothing to do here. If, however, there is text below Localhost, we must first see what that text is before we can tell you whether it is something added by the hijacker or it’s from a regular program.


    Step 5 Important!: If, while completing this step, you are not sure if a given item should be removed from the Registry, we strongly advise you to ask us about it using the comments section rather than outright deleting it because, if the item is from your OS and not from the hijacker, its deletion may damage the system. Go to the Registry Editor by typing regedit in the Run window from the previous step and then clicking on OK. Windows will most likely require your permission as an Admin – click on Yes if/when that happens. In the window of the Registry Editor, first go to Edit (the menu from the top) and then select Find. In the search box that appears, type the name of the unwanted app (Odestech), and click Find Next. Whatever Odestech items gets found, delete it, and perform a second search.

    Use the search bar o the Registry to find and delete all Odestech items, and then navigate to the Registry directories we’ve shown below by expanding the different folders from the left panel.

    • HKEY_CURRENT_USER/Software/Random Directory
    • HKEY_CURRENT_USER/Software/Microsoft/Windows/CurrentVersion/Run
    • HKEY_CURRENT_USER/Software/Microsoft/Internet Explorer/Main

    Any items with very long and/or random-looking names that you find in those locations, you must delete (preferably after you consult us via the comments section). An example of an item that you may find in those directories and that you should delete is “das90u13rjf0f1039i09ritgj09fj3029“.

    Step 6 Even though you cleaned our browsers at the start of the guide, it’s advisable that you check them once again. Star by going to the icon of your main browser, right-clicking it, and selecting Properties. From there, go to the Shortcut section of the Properties window, and take a look at the Target field – anything that’s written in there after “.exe” ought to be deleted, so go ahead and do that, and then click on OK. The next thing to do is to start the browser, click on the icon of its menu (in most browsers, that icon is in either the top-left or the top-right corner of the window), and then go to Extensions/Add-ons. To see the Extensions option in Chrome, you must first click on More Tools in the browser menu. Next, what you should do is check the extensions listed on that page for anything that shouldn’t be there, and disable and uninstall any possibly unwanted items. Needless to say, if any of the unwanted add-ons you deleted earlier have returned to the browser, you must delete them again.

    The next thing to do is to open the browser menu once more and this time click on Settings (or Options).


    On the Settings/Options page, what you should do is find the Privacy and Security settings section, click on it, and then select Clear Browsing Data (in the Microsoft Edge browser, select the Choose what to clear option).


    Leave only the Passwords box unchecked and then Clear the browsing data.


    Finally, do not forget to repeat this process for your other browsers.

    If you are still having problems with Odestech If this guide didn’t help and Odestech is still troubling you, then you must consider the possibility of an additional malware program hiding in the computer and allowing Odestech to remain active. In such cases, it is suggested to use specialized software for removing the hijacker and any other unwanted programs from your computer. The tool we would recommend for this job is linked on this page – we advise you to give it a try and let it clean your system from anything unwanted and/or hazardous.
