How to remove “Error # 268D3-XC00037” Fake Alerts (Microsoft Scam)

If your web browser is constantly being redirected to sites that display a “Error # 268D3-XC00037”notification, asking you to call a support number to fix it, then it is possible that you have adware program installed on your computer.

These “Error # 268D3-XC00037” alerts are nothing more a scam. Microsoft does not send unsolicited email messages or make unsolicited phone calls to request personal or financial information or fix your computer. Treat all unsolicited phone calls or pop-ups with skepticism. Do not provide any personal information.

The bogus “Error # 268D3-XC00037” alert is shown in such a way as to trick the user into thinking their computer has crashed or that a virus has been detected on the computer. It does this to try and scare the infected user into calling one of the listed numbers in order to receive support. In reality, though, they will only be greeted with people who are trying to sell them unneeded support contracts and services.
The “Error # 268D3-XC00037” pop-up will have this message: says:
Error # 268D3-XC00037
Please call us immediately at
Do not ignore this critical alert.
If you close this page, your computer access will be disabled to prevent further damage to our network. Your computer has alerted us that it has been infected with a virus and spyware. The following information is being stolen…
> Facebook Login
> Credit Card Details
> Email Account Login
> Photos stored on this computer
You must contact us immediately so that our engineers can walk you through the removal process over the phone. Please call us within the next 5 minutes to prevent your computer from being disabled. Toll. Prevent this page from creating additional dialogues.
The scammer will typically attempt to get the victim to allow remote access to their computer. After remote access is gained, the scammer relies on confidence tricks typically involving utilities built into Windows and other software in order to gain the victim’s trust to pay for the supposed “support” services, when the scammer actually steals the victim’s credit card account information.

This step should be performed only if your issues have not been solved by the previous steps.

Google Chrome

Google Chrome has an option that will reset itself to its default settings. Resetting your browser settings will reset the unwanted changes caused by installing other programs. However, your saved bookmarks and passwords will not be cleared or changed.

Click on Chrome’s main menu button, represented by three horizontal lines. When the drop-down menu appears, select the option labeled Settings.
Chrome’s Settings should now be displayed in a new tab or window, depending on your configuration. Next, scroll to the bottom of the page and click on the Advanced link (as seen in the below example).

Chrome’s advanced Settings should now be displayed. Scroll down until the Reset browser settingssection is visible, as shown in the example below. Next, click on the Reset settings button.

A confirmation dialog should now be displayed, detailing the components that will be restored to their default state should you continue on with the reset process. To complete the restoration process, click on the Reset button
 Internet Explorer

You can reset Internet Explorer settings to return them to the state they were in when Internet Explorer was first installed on your PC.

pen Internet Explorer, click on the “gear icon” IE Icon Gear in the upper right part of your browser, then click again on Internet Options.

In the “Internet Options” dialog box, click on the “Advanced” tab, then click on the “Reset” button.

In the “Reset Internet Explorer settings” section, select the “Delete personal settings” check box, then click on “Reset” button.

When Internet Explorer has completed its task, click on the “Close” button in the confirmation dialogue box. You will now  need to close your browser, and then you can open Internet Explorer again.

Mozilla Firefox

If you’re having problems with Firefox, resetting it can help. The reset feature fixes many issues by restoring Firefox to its factory default state while saving your essential information like bookmarks, passwords, web form auto-fill information, browsing history and open tabs.

In the upper-right corner of the Firefox window, click the Firefox menu button ([Image: Firefox Menu button]), then click on the “Help” ([Image: Firefox Help button]) button.

From the Help menu, choose Troubleshooting Information.
If you’re unable to access the Help menu, type аbout:support in your address bar to bring up the Troubleshooting information page.

Click the “Refresh Firefox” button in the upper-right corner of the “Troubleshooting Information” page.

To continue, click on the “Refresh Firefox” button in the new confirmation window that opens.
Firefox will close itself and will revert to its default settings. When it’s done, a window will list the information that was imported. Click on the “Finish“.

Your old Firefox profile will be placed on your desktop in a folder named “Old Firefox Data“. If the reset didn’t fix your problem you can restore some of the information not saved by copying files to the new profile that was created. If you don’t need this folder any longer, you should delete it as it contains sensitive information.

Tragically this is a very LONG video and nothing truly occurs toward the end other than telling them you are on to them. I need to see something that would taint their PC so they can't do this to others.
