Poshukach Virus


Poshukach

Poshukach is a browser hijacker capable of opening new browser windows and tabs without user permission and to spam the screen with ads. Poshukach aims to land users on specific web pages and boost the traffic to certain sponsored websites.

Poshukach

The Poshukach virus may install different extensions in the main web browser without asking for approval from the users.

If you seek to improve your web browsing experience, you can choose from thousands of web browser extensions, add-ons, plug-ins, and other helping components that can easily integrate with popular browsers like Chrome, Firefox, Safari, Edge and others. Most of them will typically promise to make your web browsing faster or safer, or provide you with some helpful function that the browser normally lacks.

Poshukach Search

Poshukach Search is a program that is somewhat similar to the standard browser extensions. However, there is a significant difference in the way the Poshukach Search operates and that difference is the reason security experts categorize it as a browser hijacker.

Unlike a normal browser add-on which may provide you with some useful functionality, Poshukach may become a source of browsing interruptions, disturbance, and irritation. The major thing this browser hijacker could do is it can replace the homepage of the browser and change the search engine with a predefined one. Another thing that programs like Poshukach and Humisnee. may do is fill the screen with various advertisements, pop-ups, banners, and promotional messages which trigger redirects to sponsored websites and cannot be removed neither with an ad-blocker nor manually.

Though not as extreme as, for instance, Ransomware file encryption, this unwelcome generation of ads and the unauthorized browser modifications could be quite annoying. In many instances, the ads will cover the exact part of the website you’re interested in and you’d always have to click on the ad to get rid of it. However, once you click, you may get redirected to some other website – one filled with more advertisements, pop-ups, banners, and similar promotional content.

There’s no need to get into more detail about how annoying this behavior might be, but we do need to explain how these ads, random page redirects, and unauthorized browser changes to the homepage or to the default search engine can potentially lead to security hazards. Due to the unregulated activity of the browser hijacker, you might get routed to some suspicious and dangerous web address. This, in turn, could significantly increase the likelihood of getting infected with viruses, Ransomware, Trojans, or other malware that won’t do any good to your machine.

That’s why, our suggestion is to do your best to regain control over your web browser and to uninstall all the browser hijacker-related components that trigger page-redirects and aggressive ad generation.

You can do that manually, by using the instructions from the removal guide below. The steps there will help you detect and remove all the relevant files and browser components that might have been introduced by Poshukach. Another quick and risk-free way to uninstall the browser hijacker is to use a professional removal tool. Such software is specialized in dealing with potentially unwanted programs and can quickly rid you of the undesired program without any risk of accidental deletion of critical system files. If you don’t have such a tool but you need to arm yourself with one or you simply don’t have the time to go through all the instructions in the manual removal guide, you can use the professional anti-malware software recommended on this page.

Remove Poshukach virus

Browser hijackers like Poshukach may install different extensions in the main web browser without asking for approval from the users. These extensions typically help the hijacker to perform its activities but once they are removed, things get back to normal. That’s why a suggestion that we have for you before you dig into the detailed removal guide belwo is to try to find and remove the Poshukach extensions from your browser and check if that solves your browsing-related issues:

  1. From the hijacked browser’s main menu select More Tools (or Add-ons).
  2. After that search for the Extensions tab and open it.
  3. Take a look at all the extensions that have been installed in the browser and if you find anything that you believe is linked to Poshukach or looks like an Poshukach extension, remove it. There should be a Trash bin or remove button next to it.
  4. Restart the browser and see how it behaves now.

If Poshukach still shows signs of its presence and is bothering you, then you need to follow the elaborate instructions in the removal guide below in order to fully uninstall the browser hijacker from your system.


Step1

For the smooth and flawless removal of Poshukach, you will be asked to reboot your computer in Safe Mode. Before you do so, however, make sure that you Bookmark this page so you can get back to the removal guide and its instructions after the system reboots.

Once the computer reboots in Safe Mode, press CTRL + SHIFT + ESC keyboard keys together to open the Windows Task Manager.

It could be a process that is named after Poshukach or simply a process with an odd name that uses too much RAM or CPU without any particular reason.

    Step3

    With the help of the Start and Rkey combination, open a Run dialog box and type appwiz.cpl in it.

    Next, click OK.

    appwiz

    A Control Panel window will appear on the screen, displaying a list of all applications that are presently isntalled on your computer. Carefully scroll the list and search for bogus applications that have been installed recently and might be linked to the introduction of Poshukach on your system. If you find such apps, Uninstall it/them. This will prevent the browser hijacker from reinstalling itself after you complete the guide.

    Next, close the Control Panel window and type msconfig in the windows search field.

    Select the result and you will find yourself in the System Configuration window. Click on the Startup tab and search for items that are linked to Poshukach and are set to start upon the system’s startup. If you find any, you need to disable them by removing their respective checkmark from the checkbox. Don’t forget to click OK to save your changes at the end.

    msconfig_opt

    Step4

    Open a new Run dialog box by pressing Start and R keys together. Copy + paste the line below in the Run box:

    notepad %windir%/system32/Drivers/etc/hosts

    Press Enter and a file named Hosts will open on the screen. In the file, find where it is written Localhost and check if there are some strange IPs at the bottom. Look at the image below:

    hosts_opt (1)

    If there are suspicious IPs below “Localhost“, like the ones shown on the example image above, please leave us a comment with a copy of the IPs so we can take a look at them and tell you if they represent any danger.

    After you have checked your Hosts file for changes, it is time to head to Network Connections (type it in the Start menu search box) and check for any DNS changes in your settings.

    1. Right-click on the Network Adapter you are using >>> Properties.
    2. Select Internet Protocol Version 4 (ICP/IP) and click on the Properties button.
    3. Select the Obtain DNS server automatically option and then click on Advanced
    4. After that, in the Advanced window, click on the DNS tab and remove any rogue DSN in the field.
    5. Finally, click OK to save the changes.

    Rename the Folder to Backup Default

    Change the name to the selected folder to Backup Default and save it that way. Then restart the browser.

    Step6

    A quick check of the Registry for entries related to Poshukach will ensure that there are no components that are left behind. that’s why we recommend that you open the Registry Editor (Type Regedit in the windows search field and press Enter) and then use the Find function (press CTRL and F together) to type the browser hijacker’s Name in it and perform a search. If any results are found, right-click and delete them.

    If nothing shows up this way, go manually to these directories and delete/uninstall them:

    • HKEY_CURRENT_USER—-Software—–Random Directory.
    • HKEY_CURRENT_USER—-Software—Microsoft—-Windows—CurrentVersion—Run—Random
    • HKEY_CURRENT_USER—-Software—Microsoft—Internet Explorer—-Main—-Random

    Attention! Do not delete entries from the Registry if you are not 100% sure they are part of the problematic program. Any wong deletions and changes may make your computer unstable and cause more harm than good.

    If you have any questions or concerns, we would like to know about them in the comments section below this guide. In case you don’t find the steps on this page helpful, you can still remove Poshukach by using a trusted professional removal tool.
