If XProtect detects you've downloaded malware, it will let you know and move the file straight into the Bin. XProtect is kept up-to-date independently of system updates, so you won't need to restart your Mac to get the latest signatures. Signatures are telltale signs that a file is in fact a malicious virus, and means it doesn't need to be intensively scanned to work out that it's harmful.
