[QUOTE="JM Safe, post: 759173, member: 35684"] Your post is not totally correct. When a new file is downloaded or modified, etc. There are different events: creation, modify, deletion, etc. AVs could have some methods (pieces of source code) that can handle each of those events. So AVs monitor each new files on the OS and a well written product should skip by default system files (but verifying that they aren't false system files, so malware hidden in critical folders such as [CODE]AppData, Win32, etc.[/CODE] A monitor could be done like this (it is only an example): [CODE]public bool creationEvent() { string filePath=component.getEventFullPath(); bool b = scan(filePath); return b; }[/CODE] So yes an AV well developed monitors all files.
