When you get tricked by a phishing mail and open a document attachment that has a malicious macro or a link to a malicious site, or you download an infected application, there’s a file that antivirus software can scan as it’s saved to or opened from disk, and there’s a trail of file activity that you can look back at if you’re trying to review the damage done.
