Perform a Clean Uninstall of McAfee Antivirus Tool

To be honest, McAfee antivirus sometimes acts more like malware than like a tool that should protect you from it. Because it leaves behind files and registry entries, it can still cause problems on people’s computers even after it has been uninstalled. This BSOD is one of these errors, and it can be fixed by removing McAfee antivirus in a clean way.

1. Click the “Start” button and then search for “Control Panel” to open it.
2. If you have Windows 11/10, you can also click on the icon that looks like a gear to open the Settings tool.
3. Set the View as setting in Control Panel’s upper right corner to “Category,” and then click on “Uninstall a Program” in the Programs section.
4. If you are using the Settings app on Windows 11/10, clicking on Apps should bring up a list of all the programs and tools you have installed on your PC right away.
5. Find McAfee Antivirus in Control Panel or Settings and click Uninstall or Remove.
6. If a box pops up asking if you’re sure you want to uninstall McAfee Antivirus, you should click “Yes” and then follow the steps in the uninstallation wizard.

Further analysis of dump files from users who saw this error showed that several old drivers had to be updated to stop the error from happening.

1. Click the “Start” button in the lower left corner of the screen.
2. Type “Device Manager”.
3. Click the first result.
4. If you are using an older version of Windows, you can also use the Windows Key + R key combination.

Why does the attempted switch from DPC error happen?

Delayed Procedure Call is what DPC stands for. The tried switch from DPC error happens when your computer tries to turn off while it is starting up. Since this can’t be done, the DPC causes the error and the “blue screen of death” that you will see. The easiest one is that you installed a new program that isn’t working right. If this is the case, you can reinstall the software to see if the problem goes away. There may also be a problem with the way you remember things. You might lose some of your memory, or a virus or other malware might get into it. The blue screen of death can happen when the drivers for different hardware don’t work well together.
