Pu6 Virus


Pu6 is commonly referred to as a browser hijacker due to its ability to alter the behavior of your main browsing program. Pu6 can do this by means of taking over of the settings of your browser, be it Chrome, Firefox, Edge or some other one.

And the settings that it usually affects are those that have to do with the browser’s homepage, and very often with its default search engine as well. Furthermore, these are typically the very first changes that strike users once they start their browsing program for the first time after the infection has occurred. In addition, many also report seeing new toolbars in the browser, unfamiliar buttons, etc. Upon deeper investigation you may also come across new add-ons or browser plugins.

But perhaps the most annoying symptom of a browser hijacker infection like Luckypushwinner or Time4news.net, is the increase of online ads that users become exposed to. Only unlike the regular banners and popups you may see during your browsing sessions, these are actually generated by your browser – all with the help of Pu6. What’s more, these ads are quite noticeably more aggressive than your typical online adverts. Hence, you might find it at some point very difficult to dodge them, which only fuels the frustration that follows infections like this.

Last but not least in this list of irritating traits are the page redirects that software like Pu6 causes your browser to trigger. These can happen at any point in time and they’ll take you to various websites that pay for their promotion. But since you’re here, it’s safe to assume that you’ve already had a good taste of what all of this is like and you’re probably dying to find a solution for this problem. And we’re happy to announce that, indeed, you have arrived.

Below we’ve compiled a removal guide specially for Pu6 that contains a series of steps you will need to follow in order to completely uninstall the hijacker from your system. Once you have taken care of this, you will be free to reset the settings of your browser and once again surf the web in peace.

The Pu6 Virus

Browser hijackers like the Pu6 virus are generally seen as potentially unwanted programs or PUPs, which means that they don’t really benefit the end-user in any way, but they also lack the harmful properties of malware and computer viruses. Hence, the Pu6 virus will not be able to directly damage your PC.

Nevertheless, because of the endless amounts of ads that it exposes you to, along with the page redirects we mentioned earlier, there’s a risk of at some point landing on a page that’s not safe or downright dangerous. Thus, you could potentially land an infection with actual viruses like Trojans, ransomware, rooktits and more. With this in mind, it’s best to try and avoid interactions with any of the sponsored content that Pu6 tries to push on you.

Instead, it’s smarter, safer and even simply just more convenient to remove the software responsible for all this advertising nonsense.

Remove Pu6 Virus

The following quick directions have reportedly helped some users to successfully remove Pu6 from their browser: 

  1. Start the browser that is problematic and tap on its Settings.
  2. After that select More Tools/Add-ons and see the Extensions tab.
  3. Once you find it, click it to see all extensions that are presently installed in your hijacked browser.
  4. If you find Pu6 (or some other unwanted extensions that look suspicious or are potentially unwanted) in the list, remove it.
  5. Then, restart your browser to see if it operates normally.

If you still keep experiencing issues with your browser and Pu6 is the source, then try to more detailed directions in the manual removal guide below: 


It is advisable that you first Bookmark this page by clicking on the bookmark icon in the upper right corner of your browser’s URL bar to save this page for quick reference. After you do that, we recommend that you do a system reboot in Safe Mode. Use the instructions in the provided link if you don’t know how to do that and then come back to this page to complete the next steps.


When the computer launches in Safe Mode, use the CTRL + SHIFT + ESC keyboard keys combination and start the Windows Task Manager. Once it opens, click on Processes (Details in Windows 10) and take a look at the listed processes there. If you detect a process that has the Pu6 name in it or consumes way too much RAM and CPU than any other legitimate process, right-click on it and select Open File Location.


After that, use the free online scanner listed below to scan the files located in that file location for malicious code:

Each file will be scanned with up to 64 antivirus programs to ensure maximum accuracy
This scanner is free and will always remain free for our website's users.
This file is not matched with any known malware in the database. You can either do a full real-time scan of the file or skip it to upload a new file. Doing a full scan with 64 antivirus programs can take up to 3-4 minutes per file.

    This scanner is based on VirusTotal's API. By submitting data to it, you agree to their Terms of Service and Privacy Policy, and to the sharing of your sample submission with the security community. Please do not submit files with personal information if you do not want them to be shared.

    In this way, you can easily check if the process that you have found suspicious is really related to Pu6. In case the scan results show that there is a danger in the scanned files, go back to the Task Manager, right-click the related process, and select the End Process Tree option. Also, delete the dangerous files and their folders from their file location.

    If you find more suspicious processes in the Processes tab, feel free to run their files through the scanner above to determine if they also need to be stopped or not.

    Attention! Before stopping any process or deleting its files from the computer, make sure you research it online in order to rule out the possibility of stopping a legitimate system process that may destabilize the operation of your OS.


    In the second step, you need to search for bogus apps that may be related to Pu6 or that might have brought the browser hijacker into the computer. For that, press the Start and R keys from the keyboard and type appwiz.cpl in the Run window that pops up:


    To run the typed command, click on the OK button.

    Next, view each of the apps installed on your computer and search for Pu6 or apps that might be linked to it, and as soon as you find anything that you believe is potentially unwanted or could be related to the browser hijacker, select it and click the uninstall option at the top. 

    The next thing that you should do is search the Startup entries of your computer for Pu6 or its helper components. This can be done when you open the System Configuration (type it in the Windows search field and open the result) and then click on the Startup tab to view all Startup items. If you detect an item that is clearly operated by Pu6 or has an unknown manufacturer and looks suspicious, simply uncheck its checkmark and click ok the OK button to save the changes. This should be enough to stop the entry from launching when the system starts.

    Note! Please, pay close attention when unchecking the items from the Startup list as disabling important system entries may have an impact on the flawless operation and performance of your computer.



    To remove parasite on your own, you may have to meddle with system files and registries. If you were to do this, you need to be extremely careful, because you may damage your system.

    If you want to avoid the risk, we recommend downloading SpyHunter
    a professional malware removal tool.

    More information on SpyHunter, steps to uninstallEULAThreat Assessment Criteria, and Privacy Policy.

    After you are done with the Startup entries in the System Configuration window, close it and type Network Connections in the Windows search field. Open the result and repeat the directions below just as they are shown:

    1. Right-click on the Network Adapter that you are using and select its Properties.
    2. In the new window find Internet Protocol Version 4 (ICP/IP) and tap on it.
    3. Then, click the Properties button below.
    4. Make sure that Obtain DNS server automatically is selected and click on the Advanced button at the bottom.
    5. In the DNS tab of the new window that opens remove everything that has been added in the DNS server addresses section.
    6. Click on the OK button once you are done to confirm the changes.


    The next thing that you need to do is search the Registry for Pu6-related entries and remove these entries safely, without making other changes. Here are the instructions for that:

    • In the Windows search field type Regedit, and press Enter.
    • Next, press CTRL and F keys at the same time to open a Find window in the Registry Editor.
    • Type the browser hijacker’s name in the Find window.
    • Click on the Find Next button to search for Pu6-related entries.
    • If any results are found, right-click on each of them to delete it. 

    Next, manually navigate to the directories that have been listed below and delete/uninstall them to get rid of any traces that might have been left out:

    • 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! Deleting directories from the Registry may hide risks for the smooth operation of your OS. In case you are confused about which directory should be removed, don’t hesitate to leave us a comment below this post so we can assist you.


    In the fourth step, we will show you how to check your computer for hacking signs. For that, you need to access the Hosts files of your computer in the following way and check for suspicious IP addresses in it:

    • Press the Start and R keyboard keys at the same time and copy the  following command in the Run window:
    • notepad %windir%/system32/Drivers/etc/hosts
    • Click on the OK button to run the command.
    • The Hosts file will open. This is a simple text file that contains various details.
    • Scroll it until you find where it is written Localhost.  
    • Then take a look at the example image below and see if in your Hosts file you detect some questionable IP addresses like the ones in the image:

    hosts_opt (1)

    Normally, there shouldn’t be anything disturbing. If you do find questionable IPs in your Hosts file, please, leave us a comment below this post and a member of our team will do its best to advise you on what to do next.


    Pu6 may easily hijack many different browsing apps. Thus, if you are using more than one on your computer, you should revoke and changes that the unwanted app might have made in them without your knowledge or approval. The instructions below explain how to do that in three of the most popular browsers, namely Chome, Internet Explorer and Firefox, but the steps shouldn’t be very different in other browsers as well.
