Here you can choose whether the virus check should be done on the local hard drives, whether memory and autostart areas should be tested, or if you only want to test certain directories and files. If this is the case, use the Selection button to specify the directories you want.
Check following directories and files: In the directory tree, you can open and select directories by clicking on the plus symbols. Their contents will then be shown in the file view. Each directory or file that you mark with a check will be scanned by the software. If not all files in a directory are checked, this directory is marked with a grey checkmark.
