The Block at first sight feature only uses the cloud protection backend for executable files that are downloaded from the Internet, or originating from the Internet zone. A hash value of the EXE file is checked via the cloud backend to determine if this is a previously undetected file. - + If the cloud backend is unable to make a determination, the file will be locked by Windows Defender AV while a copy is uploaded to the cloud.
