Your Windows (Microsoft) Computer has been blocked - a scam that creates a legitimate look by misusing the name of Microsoft

"Your Windows (Microsoft) Computer has been blocked" is a scam that pretends to be from Microsoft helpline.

This type of message typically occurs when infected with a technical support scam virus under which another potentially unwanted program such as adware might be hiding. The so-called TTS scammers seek to trick users into calling the fake Microsoft support number.

However, if you see such messages opening in new browser windows or tabs, and if the sites that provide such "information" about your computer status send you additional pop-up alerts that are hard to close, you should not panic and not rush to call a number provided.

You need to scan the entire system with a tool such as and remove Your Windows (Microsoft) Computer has been blocked together with its cause.

If you tried calling these people who have provided you with Your Windows (Microsoft) Computer has been blocked scam, they would try to convince you to buy a useless piece of software, provide them with personal information, or even ask you to give them remote access to your computer so that they could "fix" your PC. Usually, instead of providing help, they just drop malware on the computer.

How Your Windows ads got into your browser

From our report of Jun 2019 · not reviewed since

Scareware can be unintentionally downloaded from untrustworthy Internet sites along with other free programs.

Such deceptive method is known by the term "bundling". According to Virusai.lt, the best way to avoid such activity is to choose the Advanced or Custom configuration that allows the user to control all incoming programs and choose which are worth downloading to the system and which are not. All Recommended/Quick modes should be avoided.

Potentially infectious apps sometimes might also spread via malvertising campaigns and through infectious hyperlinks that are placed in P2P sites. The best option to secure your PC from such misleading programs is to protect it by placing an anti-malware software on it. Of course, you can try to avoid misleading ads and install programs with cautions, but remember that one day, malware might still trick you into installing it.

How to remove Your Windows ads

How to remove the Your Windows extension

Do the browser steps in every browser and profile on the PC, then check Windows for the program that installed the extension.

  1. Step 1: Remove extensions you did not add

    In Chrome open chrome://extensions, in Edge edge://extensions, and in Firefox the menu > Extensions and themes.

    Remove every extension you do not remember adding, especially search, new tab, coupon, PDF, weather or video downloader add-ons. Check every browser and every profile, because each keeps its own list.

    If an extension has no Remove button or comes back, a browser policy holds it (see "Managed by your organization" in the procedure below). The pages are the same on Windows 11 and Windows 10.

    Chrome menu with Extensions and Manage extensions highlighted
    Chrome on Windows 11: More > Extensions > Manage extensions.

    Full procedure with screenshots: Remove a browser extension

  2. Step 2: Uninstall Your Windows

    Your Windows is removed like any other program, from the list of installed apps. In Windows 11 that is Settings > Apps > Installed apps, in Windows 10 Settings > Apps > Apps & features, and in both you can also use Control Panel > Programs and Features.

    Select Your Windows, click Uninstall and follow the uninstaller to the end. Then look at the entries just above and below it when the list is sorted by date: bundled programs install at the same minute.

    Full procedure with screenshots: Uninstall a program or app in Windows On uGetFix

  3. Step 3: Reset the browser

    A reset removes what the steps above could miss:

    • changed start pages
    • site permissions
    • hidden settings

    In Chrome open Settings > Reset settings > Restore settings to their original defaults; in Edge Settings > Reset settings; in Firefox Help > More troubleshooting information > Refresh Firefox.

    Tip: Bookmarks and saved passwords stay, while extensions are turned off and the search engine and start page return to the defaults.

    Reset every browser on the PC, including Edge, which Windows 11 and Windows 10 always have.

    Chrome Settings page with the Reset settings section open
    Chrome on Windows 11: Settings > Reset settings.

    Full procedure with screenshots: Reset a browser and fix a hijacked search engine

  4. Step 4: Scan the PC, then run the offline scan

    A scan finds the parts of Your Windows that the manual steps cannot see. In Windows Security > Virus & threat protection > Scan options, start a Full scan and quarantine what it reports.

    Follow it with Microsoft Defender Antivirus (offline scan) > Scan now, which restarts the PC and checks the disk while Windows and the malware are not running.

    It takes about 15 minutes and works the same in Windows 11 and Windows 10. If either scan finds something, run the full scan again after removal until it comes back clean.

    Windows Security Scan options with Microsoft Defender Antivirus offline scan selected
    Windows 11: Windows Security > Virus & threat protection > Scan options.

    Full procedure with screenshots: Run a Microsoft Defender Offline scan

Avoid any unwanted government tracking or spying by going totally anonymous on the internet.

You can choose a different location when you go online and access any material you want without particular content restrictions. You can easily enjoy internet connection without any risks of being hacked by using VPN.

Control the information that can be accessed by government any other unwanted party and surf online without being spied on. Even if you are not involved in illegal activities or trust your selection of services, platforms, be suspicious for your own security and take precautionary measures by using the VPN service.

Backup files for the later use, in case of the malware attack

Computer users can suffer from data losses due to cyber infections or their own faulty doings.

Ransomware can encrypt and hold files hostage, while unforeseen power cuts might cause a loss of important documents.

Learn how to remove Your Windows (Microsoft) Computer has been blocked pop-ups

Your Windows (Microsoft) Computer has been blocked virus must be eliminated without regret since it is a useless program.

It seeks to frighten the user and cause a perception of fear to convince the victim to buy a fake anti-virus program or even allow some fake computer technicians to connect to his/her computer remotely.

Do not be fooled; identify this threat with a real anti-malware software and remove it right away. Your Windows (Microsoft) Computer has been blocked removal can be completed with reputable anti-malware software. Bear in mind that the manual elimination technique requires more of the user's effort and takes more time.

However, you still can remove "Your Windows (Microsoft) Computer has been blocked" from your Windows computer system manually.

Questions about Your Windows ads

Can I safely uninstall Your Windows?

If you did not install Your Windows yourself and it is not part of your hardware or a program you rely on, yes. Uninstalling an unwanted program does not harm Windows. Before you do, search the exact name and publisher to be sure it is not a driver tool, a printer utility or a game launcher with an odd name.

Then remove it from Settings, Apps, Installed apps. Ignore any offers or warnings in its uninstaller about losing protection or performance. Afterwards check Startup apps and your browsers for leftovers, and restart once to confirm that it does not reinstall itself.

How do I stop programs like Your Windows from being installed again?

Most unwanted programs arrive through installers, so the fix is in how you install software. Download programs from their official sites or the Microsoft Store, not from download portals or ads above search results. During setup, choose Custom or Advanced installation and untick every extra offer, including browsers, toolbars and optimizers.

Decline update prompts that appear inside other programs unless you know them. In Windows Security, turn on reputation-based protection and potentially unwanted app blocking. These steps would most likely have stopped Your Windows before it reached the app list.

Can adware slow down my PC?

Yes. Adware runs in the background, loads ad scripts, opens extra tabs and contacts its servers, all of which use processor time, memory and bandwidth. Ad-heavy extensions also slow down every page, because they inspect and change it before you see it.

The effect is strongest on older PCs and when several adware programs arrived together. After removal, restart the PC and check Task Manager for anything still using a lot of resources that you do not recognise. Speed usually returns to normal once the ads stop.

I clicked on one of the ads. Am I infected?

Probably not. Clicking an ad usually only opens a page, and a page cannot install programs on an up-to-date Windows PC without your help.

You are at risk only if you then downloaded and ran a file, allowed notifications, entered card or login details, or called a phone number shown on the page. Delete any download and run a full and offline scan.

Change passwords you typed, from a clean device. Call your bank if you gave card details. If you called a number or allowed remote access, see the next question.

Why didn't my antivirus catch Your Windows?

Many security products do not block adware or notification sites by default, because users often agreed to them, even through a misleading prompt. Notification spam installs nothing at all, so there is no file to detect.

In Windows 11 you can make Microsoft Defender block potentially unwanted apps: open Windows Security > App & browser control > Reputation-based protection settings and turn on Potentially unwanted app blocking. If notifications caused the pop-ups, no scanner will report them; the fix is in the browser's site settings.

An ad showed a phone number and I called it. What now?

The number belongs to scammers, not to Microsoft or an antivirus company. If you only talked, hang up and do not call back. If you let them connect to the PC, disconnect it from the internet, uninstall the remote access program they used, such as AnyDesk, TeamViewer, ScreenConnect or UltraViewer, and run a full and offline scan.

If you paid or gave bank details, call your bank at once on the number printed on your card. Change any passwords you typed while they were connected, and report the call.

Does adware steal passwords?

Ordinary adware is built to show ads, not to steal logins, and most of it never touches saved passwords. The line is blurry, though. Extensions that can read every page could capture what you type, and adware ads sometimes lead to phishing pages that ask for passwords directly.

If you entered credentials on a page reached through an ad, change that password from a clean device and turn on two-step verification. Otherwise, removing adware extension and clearing cookies is usually enough.

What is Your Windows?

"Your Windows (Microsoft) Computer has been blocked" is a scam that pretends to be from Microsoft helpline. This type of message typically occurs when infected with a technical support scam virus under which another potentially unwanted program such as adware might be hiding.

The summary table at the top of this guide lists the type, the detection names, the symptoms and the damage of Your Windows. Reading it first helps you decide whether your computer shows the same signs. The removal plan below it works in order, from the safest step to the more thorough ones.

Will Fortect remove Your Windows?

Fortect scans Windows for malware and unwanted programs and repairs the system files and settings they change, and its free scan shows what it finds on your PC before you decide anything.

For Your Windows, follow the plan above as well: the browser steps take back permissions and settings that no scanner treats as a threat, and uninstalling the program that brought it removes the source.

Run Microsoft Defender's full scan and, if anything was found, its offline scan as a second opinion. If the symptoms are gone after the plan and both scans are clean, there is nothing more to do.
