Antivirus Scanner Software
Where to get it
Updated 04/30/2022
This is a list of free antimalware scanners that are readily available on your PC, on the Internet, or can be downloaded and installed on your PC.
None of the software tools in this list are meant to be replacements for your installed active antivirus/antimalware software.
But if you need an active antivirus program suite see my Internet Security Software Vendors List.
On your Windows PC:
Microsoft Malicious Removal Tool
If Windows Update is turned on to automatically download and install Windows Updates then a recent copy of the Microsoft Malicious Removal Tool is present on your PC.
To use the MRT scanner simply enter MRT into the Search box, either in the Start Menu or in the Start Sceen. MRT should be the top or near the top choice.
IMPORTANT! Run the MRT with Administrator privileges - right-click MRT then chose RUN AS ADMINISTRATOR from the context menu.
If you have no antivirus scanner software installed this is much better than nothing.
