This video will go through how to set up ClamAV on Windows, the documentation is not really clear so these are the steps you need to take to set up the ClamAV open source antivirus scanner and get it ready to start scanning folders/files for you
Note that this is not an automatic scan, you need to manually specify what you want to scan, in general if you are on Windows operating system you should probably use Windows defender which is a more easy to use solution.
