Hi. I have been using the latest KAV2006 beta for a few days and have a question. Actually, I suppose the question applies to any antivirus with this option. Is there some reason why I would not want to use the option (in several places) to scan only new and changed files? Is there less protection this way? KAV offers this and I don't know what other programs do. I have NOD on a laptop but cannot remember if it has the option only to scan new and changed files. If the protection is the same, this seems like a great time saver. Thanks.
