How to temporary disable auto scan of removable drives



We're using Server Security 12.11 b. 103 on our MS Server 2008 R2 Standard.

We have 2 sets of external backup drives and rotate them once a week.


Every time I re-attach different backup drive, F-secure starts scanning it, consuming server's resources - RAM and CPU which are needed for other applications.


Is there any way to exclude external backup drives from automatic scanning when they are re-attached?




Kind regards,

    Hello Ivan,


    You can exclude objects (backup drives for example) or processes (backup process for example) from Real-time scanning.

    From Policy Manager Console > Settings (Advanced view) > F-Secure Anti-virus > Settings > Settings for Real-Time protection > Scanning Options > File scanning > Inclusions and Exclusions.

    Or from Server Security Web User Interface > Server protection > Real-time Scanning > Exclude from scanning.

    Please, note, that this exclusions will work permanently. It's not possible to automatically tune them so, that they will work only for some time after the backup drives are re-attached.

    Hello Vad,


    Thank you very much for the reply.


    I noticed that my backup drives aren't assigned with drive letters, so F-Secure cannot see them as objects.


    I'll assign drive letter and set up entire disk as excluded object.


    Best regards,

    F-Secure does only  scan MBR of a removable device. Files will only get scanned when you access them.
    This (useless) kind of opeation (only allow access to the drive if fully scanned) has to be done by a windows add-on


    Assigning a drive letter will not help, if the drive is accessed without using Drive letters.
    explains why.
