Automatic startup file check

When creating a System startup file check scheduled task, you have several options to adjust the following parameters:

The Scan target drop-down menu specifies the scan depth for files run at system startup based on a sophisticated algorithm. Files are arranged in descending order according to the following criteria:

•All registered files (most files scanned)

•Rarely used files

•Commonly used files

•Frequently used files

•Only the most frequently used files (least files scanned)

Two specific groups are also included:

•Files run before user logon—Contains files from locations that may be accessed without the user being logged in (includes almost all startup locations such as services, browser helper objects, winlogon notify, Windows scheduler entries, known dll's, etc.).

•Files run after user logon—Contains files from locations that may only be accessed after a user has logged in (includes files only run by a specific user, typically files in HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Run).

Lists of files to be scanned are fixed for each group above. If you choose a lower scan depth for files run at system startup, the not scanned files will be scanned after opening or execution.

Scan priority—The level of priority used to determine when a scan will start:

•When idle—the task will be performed only when the system is idle,

•Lowest—when the system load is the lowest possible,

•Lower—at a low system load,

•Normal—at an average system load.
