  1. I ran all three of these in the exact order when this malware infected my Microsoft edge browser with no luck. I have ran multiple virus removal programs and they all come back clean, I have also searched my C drive and windows directory and found no weird files associated with this malware. When I open Microsoft edge it still starts up this malware every time with audio. Chrome works fine but I want to clear everything from my computer, any more suggestions, is there a way to reset Microsoft Edge, I thought it was built into Windows 10 so there is no way to remove and reinstall?

  2. I got this last night but my Chromebook doesn’t have Microsoft products installed on it. I will try running these tonight, if that doesn’t work, not sure what’s next. Advice?

  3. I got this yesterday on my HP laptop. Being naïve and not thinking it through, I called the number because I literally could not do anything on the computer, even turn it off. Everything seemed legit until they wanted to charge me $350 to repair the computer and remove the malware. I hung up and will try this.

  4. ”Be aware that programs and services offered are not free. ”

    But of course, as always the phone number to call is!!!

    Because they want to capture your phone number even if blocked!!!!!

  5. @Wil, to close the warning, you have to end the application or browser. To do this, press CTRL+ALT+DEL on keyboard. Click on Start Task Manager. Select the application (IE, Chrome, Firefox). Then, click on End Task.

  6. I got this today and it’s not letting me do anything. I don’t have any money so I can’t exactly purchase a virus scanner

  7. I just got this and it shut my computer down and is requiring a weird password that I don’t have. Can literally anyone help me with this? Any tiny bit of help would be appreciated

  8. The best thing to do is try bringing up the task manager (Control-Alt-Delete) whilst the pop up is still being displayed on your browser. Then find the processes Tab in the task manager and then the APPS sub heading (this is using windows 8.1 fyi)

    Select your browser eg: Firefox etc. and click the end task at the bottom right hand corner of the task manager. Once exited out of the browser it will take you back to your desktop. Now start a full anti virus search using malware bytes or your own preferred software. Once completed – be careful when clicking back onto your browser as it will remember the previous closed down pages and may open the Microsoft pop up locked account again. Try right clicking your browsers icon and select start a new session or open new tab, new page. Hope this helps out. Remember there’s a truck load of tutorials on Youtube in regards to problems like this.

    Cheers, Aleco :)

  9. I get this about 3x a month. Simply turn off computer, wait a few minutes it gone with no damage.

    I’ve tried every method to get rid of this piece of crap. Why can’t someone do anything to stop these creeps? It’s irritating as hell when this damn notice pops up. I lose all my files when I’m working on my animation programs because I have to restart my computer without any chance of saving the files. These cyber criminals should be locked up and never allowed to use a computer again.

    If you are infected with this crap, I would advise you to download and install Malwarebytes. It’s free and when I ran it, it detected 332 threats on my computer. Malwarebytes removed all the threats for free. I think a program called Adware File finder is the program that I used once that caused the problem. So, never use that program!

  12. Guys all u need to do is delete all your history and cookies from the infected browser and exit the browser then it should be back to normal. You don’t need to anything else.

  13. Okay so I received a phone call that I needed to fix my account today to prevent it from becoming blocked tomorrow from an unknown number from Microsoft. I don’t know if it’s a scam or if there is anything I can do.

  14. Malwarebytes ( the free version ) found nothing while the “alert” was still active. ( Win10) I closed Edge
    via Task Manager and then opened Google window which had several windows I had already opened.
    Then when I opened Edge, the “alert” was gone. I need to find a more powerful app or software that can power thru this alert thing. I had visited a technical websites post archives when the “alert” came up.

  15. I just had this happen to me and like a fool I phoned the number. I hung up before I downloaded anything, but the “free” phone call cost me over 10 pounds. It was to India, though…….. What I ended up doing was turn off my computer and remove the battery. I left it for about 10 minutes, turned it back on and everything seems fine. Am doing a scan now.

  16. I got this message and tried to close it but no result. I just pressed and held the shut down button until the computer turned off. Restart showed computer did not shut down correctly and just click start normally. Browser showed a restore previous page from shut down clicked that. I think the clear your browser cookies and or reset is probably a good idea.

  17. I have 268d3 on my Dell and it wont let me do anything but a hard shutdown. Anyone know how I can fix this mess? I’m a beginner, second stage, which means, I can follow directions and do things if I know where to go to do these.
    Thank you. I have Windows Professional 7.

  18. I got this error and downloaded Baidu antivirus by the way Terminator is not my real name.

  19. Go with the mouse right-down on the screen and “switch to Desktop” (that little part right in the corner, no to see with your eyes but it works if you try with the mouse) if you want to finish your work on the site you intended to go. The site with the blocking warning is also minimized and you can choose that one that you need.

    Ctrl +Alt+Del

    Choose THE BROWSER that you have opened ( and where that crap appeared), close the “red-ADOBE” FlashPlayer (will be reloaded if you need it), than choose your BROWSER on the list, “open” the list of opened-sites, mark the site with deceptive message and click “shut-down” (right-site, down corner of the Manager.

    The site with the “Alert” gets “killed”, has no power to resist to this command.

    The computer works further and the sites opened in your browser are full-operating. They were so all the time but you couldn’t access them because of that crap. An ABP with the possibility to introduce your own list of such crap-sites, is that AdBlock Plus. cannot stop all of them but you may put the sites on a blacklist “for the next time”. HOW IT COULD BE MADE, is explained very clear on the AdBlock Plus site.

  20. A recorded warning took over my PC and showed a message , supposedly from Microsoft warning my PC had been virally infected allowing others to seize financial information, passwords. And if I didn’t call 888-976-6204 within 5 minutes they would shut me down and notify the Microsoft authorities. When I called them they said they were with Microsoft Corp. The gal & guy were from India using Anglo names. This happened 9/18/2018

  21. I have Malwarebytes and downloaded Microsoft Malicious Software removal tool full scan. Neither of them found this and therefore neither quarantined or in anyway I did it.

  22. It happened to me today, I got a message from Microsoft, so I called the number displayed, as always it was a person from another county, an then it hit me when they asked for remote control of my computer, they asked for a zip code where a Microsoft store was, there are in which they said there was a store is in my small town and I know for sure that no stores there, so I Googled it online on how to restore my computer ( CTRL ALT DELETE) THEN RESTART. So being the person that I am, I called back an told them that they were common thieves that was out to take people’s money. I hate dishonest people! But they got my point in details.

  23. This crap has obviously been going on a long time. My McAfee does not stop it. Call to Microsoft went nowhere when I was unwilling to pay. Seems like they should be interested in stopping thieves impersonating them. Very, very frustrating.
