The data directory is used to store Domino email messages. Repeated scanning of this folder while it is being updated with new messages is not an efficient way to scan locally stored email. Use virus scanning applications such as ScanMail for Domino to handle email viruses. By default, the Domino data directory for a non-partitioned installation is <drive>: \ Lotus \ Domino \ Data.

Exclude the directory or partition where MS Exchange stores its mailbox. Use virus scanning applications like ScanMail for Exchange to handle email viruses. Installable File System (IFS) drive M must also be excluded to prevent the corruption of the Exchange Information Store.

  • <drive>: \ EXCHSRVR \ IMCData
  • <drive>: \ EXCHSRVR \ MDBData
  • <drive>: \ EXCHSRVR \ MDBData
  • <drive>: \ EXCHSRVR \ MTAData

  • <drive>: \ EXCHSRVR \ SrsData
  • <drive>: \ WINNT \ system32 \ InetSrv
  • <drive>: \ EXCHSRVR \ MDBData

This option is best disabled. If it is enabled, it may create unnecessary network traffic when the end users access remote paths or mapped network drives. It can severely impact the user’s experience. Consider disabling this function if all workstations have OfficeScan client installed and are updated to the latest virus signature.

  • <drive>: \ WINNT \ SYSVOL
  • <drive>: \ WINNT \ NTDS
  • <drive>: \ WINNT \ ntfrs
  • <drive>: \ WINNT \ system32 \ dhcp
  • <drive>: \ WINNT \ system32 \ dns

Web Server log files should be excluded from scanning. By default, IIS logs are saved in <drive>:\inetpub\logs\.

Web Server log files should be excluded from scanning. By default, IIS logs are saved in:

  • <drive>: \ WINNT \ system32 \ LogFiles
  • <drive>: \ WINNT \ system32 \ IIS Temporary Compressed Files
  • <drive>: \ Program Files \ Microsoft ISA Server \ ISALogs
  • <drive>: \ Program Files \ Microsoft SQL Server \ MSSQL$MSFW \ Data

Scan exclusion guidelines for Microsoft Lync:

  • <drive>: \ Documents and Settings \ All Users \ Application Data \ Microsoft \ Microsoft Operations Manager
  • <drive>: \ Program Files \ Microsoft Operations Manager 2005
  • <drive>: \ Program Files \ SharePoint Portal Server
  • <drive>: \ Program Files \ Common Files \ Microsoft Shared \ Web Storage System
  • <drive>: \ Windows \ Temp \ Frontpagetempdir
  • M:\
  • Drive:\Program Files\Common Files\Microsoft Shared\Web Server Extensions
  • Drive:\Windows\Microsoft.NET\Framework64\v2.0.50727\Temporary ASP.NET Files
  • Drive:\Users\ServiceAccount\AppData\Local\Temp
  • Drive:\Users\Default\AppData\Local\Temp
  • Drive:\Users\<the account that the search service is running as>\AppData\Local\Temp
  • Drive:\WINDOWS\system32\LogFiles
  • Drive:\Windows\Syswow64\LogFiles
Reference: Certain folders may have to be excluded from antivirus scanning when you use a file-level antivirus program in SharePoint.

Because scanning may hinder performance, large databases should not be scanned. Since Microsoft SQL Server databases are dynamic, they exclude the directory and backup folders from the scan list. If it is necessary to scan database files, a scheduled task can be created to scan them during off-peak hours.

  • <drive>:\ WINNT \ Cluster (if using SQL Clustering)
  • <drive>: \ Program Files \ Microsoft SQL Server \ MSSQL \ Data
  • Q:\ (if using SQL Clustering)
  • C:\Program Files\Microsoft SQL Server\MSSQL.X\OLAP\Data
  • File extensions to exclude: .mdf, .ldf, .ndf, .bak, .trn

  • %ProgramFiles%\Microsoft SQL Server\MSSQL.3\Reporting Services\ReportServer\Bin\ReportingServicesService.exe
  • %ProgramFiles%\Microsoft SQL Server\MSSQL.2\OLAP\Bin\MSMDSrv.exe

Considerations for clustering

You can run antivirus software on a SQL Server cluster. However, you must make sure that the antivirus software is a cluster-aware version. Contact your antivirus vendor about cluster-aware versions and interoperability.

If you are running antivirus software on a cluster, make sure that you also exclude these locations from virus scanning:

  • Q:\ (Quorum drive)
  • C:\Windows\Cluster
  • SMS \ Inboxes \ SMS_Executive Thread Name
  • SMS_CCM \ ServiceData
  • SMS \ Inboxes
  • <drive:>\ WSUS
  • <drive:>\ WsusDatabase
  • <drive:>\MSSQL$WSUS

Where "<drive:>" is the drive letter where you installed Windows Software Update Services server.

You can refer to the following Microsoft article for additional information: Multiple symptoms occur if an antivirus scan occurs while the Wsusscan.cab file or the Wsusscn2.cab file is copied

  • MySQL main directory - <Drive>:\mysql\
  • MySQL Temporary Files - Uses the Windows system default, which is usually C:\windows\temp\
  • C:\Program Files\Novell\Zenworks
  • C:\Program Files\Novell\ZENworks\logs\ExternalStore
  • C:\Program Files\Novell\ZENworks\cache\zmd\ZenCache\metaData
  • C:\Program Files\Novell\ZENworks\cache\zmd
  • Exclude the following files: NalView.exe, RMenf.exe, ZenNotifyIcon.exe, ZenUserDaemon.exe, casa.msi, dluenf.dll, fileInfo.db, lcredmgr.dll, objInfo.db
  • Exclude the following extensions: .APPSTATE, .LOG, .TMP, .ZC
  • .dbf - Database file
  • .log - Online Redo Log
  • .rdo - Online Redo Log
  • .arc - Archive log
  • .ctl - Control files
  • C:\Dokumente und Einstellungen\*\Anwendungsdaten\RA-E
  • C:\Dokumente und Einstellungen\*\Anwendungsdaten\RA-MICRO
  • C:\Dokumente und Einstellungen\*\Anwendungsdaten\RA-MICRO Software GmbH
  • C:\Dokumente und Einstellungen\*\Lokale Einstellungen\Anwendungsdaten\RA-MICRO_Software_GmbH
  • C:\Dokumente und Einstellungen\*\Lokale Einstellungen\Anwendungsdaten\RA-MICRO
  • C:\Dokumente und Einstellungen\All Users\Anwendungsdaten\RA-MICRO
  • SAP ABAP or Java installs:

    \usr\sap\

  • SAP Content Server Install:

    \SAPDB\

  • SAP Printer Server:

    SAPSprint.exe

  • Servers where are SAPGui is installed:

    lsagent.exe

  • During SAP installs or upgrades, it is recommended to exclude the base SAPinst directories and subdirectories:

    ..\Program Files\SAPinst_instdir\

  • ..\Smex\Temp
  • ..\Smex\Storage
  • ..\Smex\ShareResPool\
  • ~\Symantec\Backup Exec\beremote.exe
  • ~\Symantec\Backup Exec\beserver.exe
  • ~\Symantec\Backup Exec\bengine.exe
  • ~\Symantec\Backup Exec\benetns.exe
  • ~\Symantec\Backup Exec\pvlsvr.exe
  • ~\Symantec\Backup Exec\BkUpexec.exe

Other file extension types that should be added to the exclusion list include large flat and designed files, such as VMWare disk partition. Scanning VMWare partitions while attempting to access them can affect session loading performance and the ability to interact with the virtual machine. Exclusions can be configured for the directory(ies) that contain the Virtual Machines, or by excluding *.vmdk and *.vmem files.

Backup process takes longer to finish when real-time scan is enabled. There are also instances when real-time scan detects an infected file in the volume shadow copy but cannot enforce the scan action because volume shadow copies have read-only access.

You can refer to this KB article: Excluding Volume Shadow copies from OfficeScan client real-time scans.

It is also advisable to apply the latest Microsoft patches for the Volume Shadow Copies service. Refer to this Microsoft article: A Volume Shadow Copy Service (VSS) update package is available for Windows Server 2003.

Make sure the checkbox for "Do not scan the directories where Trend Micro products are installed." is enabled in WFBS’s Exclusion List settings (Security Settings>Antivirus/Anti-spyware>Exclusions).

 
Add the.bkf extension to the list of real-time scan exclusions.
