● Scheduled Scan
You are not permitted to run a scheduled scan in runtime.
● Pattern update
Pattern update of virus scan clients (system PCs being checked for viruses) is done by the
higher-level virus scan servers (the system PC that centrally manages the virus scan
clients).
● Dialogs
To avoid interfering with process mode, no dialog messages should be displayed on the
virus scan clients.
● Drives
Only the local drives are scanned to prevent overlapping scans on network drives.
● You can deactivate e-mail scan except on the WinCC engineering station that receives e-
mail.
Accept all other default settings.
What does this ensure?
The incoming data traffic is checked for viruses. The effect on process mode is kept to a
minimum.
Note
When using a virus scanner, make sure that the computer has sufficient system resources.
Screen savers
Using a screen saver costs processor time and can lead to a system overload. Screensavers
which no longer release parts of the working memory, continuously reduce the usable working
memory.
The Windows "Logon screen saver" can be used.
