The update server downloads updates from upgrade.bitdefender.com.
Installation files for AV Defender are downloaded from the SolarWinds MSP Server In The Sky (SIS) at http://sis.n-able.com.
If you have any internal Update Servers, it will be the first server in the list of Update Servers that are applied for signature configuration.
Based on the availability of the signature or state of the Update Server, AV Defender will select the correct server.
For information, see AV Defender Software Uninstall Limitations.
If a specific version is not listed for a competing antivirus solution, MSP N-central will attempt to locate the installer or .MSI file and append the
/s/u switches so that the software can be uninstalled. If uninstalling the software fails, please contact your Channel Sales Specialist to request that the antivirus software be added to those that AV Defender can uninstall. You can look up your PDS and their contact information in the N-able Resource Center under My Account or you can also send an email to email@example.com.
Yes. You should be running the latest version of Report Manager. If Report Manager is not updated, some security information will not be available.
If you currently have an antivirus solution deployed, you will see best results by removing the software through the competitive platform first, and then try to Installing Security Manager.
If you are using Kaseya and there is a password configured for the installer, the software will not be automatically removed. For example, Kaspersky will not be removed even if it is a supported version for removal if there is an installer password.
When removing Kaspersky through Kaseya, you may experience an issue where the uninstaller fails to remove some registry filters and leaves the USB hub/root, CD-ROM drives and some other ports unavailable and displays
Unable to start error messages in the Windows Device Manager.
This will result in keyboard and mouse being disabled if they are USB devices. To resolve these issues, you will need to run the
kavremover.exe application to manually remove the entries. On one computer, you will need to perform a system restore, reinstall Kaspersky Antivirus, uninstall it, and then proceed with the deployment of AV Defender.
If you are deploying AV Defender to Windows XP computers, clone the Default Profile - Laptops/Workstations Low Resource and use it as a template to configure your own Profile.
AV Defender requires at least 500 MB of free memory in order to function properly.
You can configure an Update Server on any Server - Windows device or any device that has a Probe installed on it. You do not need AV Defender installed on the device but when you enable it, it installs a non-functioning version of AV Defender on the device. It will not remove any existing antivirus software. The update location cannot be changed and it will store the updates at C:\Program Files\N-able Technologies\Bitdefender Update Server\var\cache\update-cache. The port used is 7074.
Ports used for AV Defender and other services include:
- 10004 – Downloading installation files
- 15000 – Patch Management
- 7074 – AV Defender Update server
The Probe automatically creates firewall rules for these ports.
The Agent pings the device. The results and where to find it are shown below. The
PatchCacheMonitor.log may be useful as it will record the Agent testing available Probes. Sample log:

This is not available to users as it was not included in the development requirements for AV Defender.
No, there is no automatic removal of outdated signature files.
MSP N-central will install a non-functioning version of AV Defender which will remove the existing antivirus solution. It is strongly recommended that you only enable Update Server on devices that have AV Defender already installed.
The Anti-phishing, Content Control, and the Network modules can trigger the display of the traffic light icon. To prevent this from being displayed when accessing a web site, you must add a Global Exclusion.
The processes that are excluded by default include all of the processes required for the Probe and Agent to run properly.
By default, AV Defender includes preconfigured exclusions following guidelines provided by MSP N-central and Microsoft. These preconfigured exclusions are embedded in AV Defender and are not subject to user modification.
The preconfigured exclusions that follow Microsoft guidelines are described at http://support.microsoft.com/kb/822158.
The MSP N-central preconfigured exclusions include:
Security Manager provides security for archived and compressed files, but certain archive formats cannot be disinfected. The table below lists popular file archive/compression applications as well as a description of any limitations placed by the archive format.
In the Disinfect column, AV Defender support is tagged as:
- No: Decompression, scanning and detection of the archive contents is possible but disinfection of infected files cannot be performed due to restrictions on updating the container.
- Yes: Disinfection and repacking of the archive container can be performed.

There are too many to list here. Modifications carry a modified unpacking code and therefore cannot be reliably packed back into the container. DBX Partial Plain MailBox Yes MBX No MIME Yes PST
AV Defender scans PST/OST files but will not quarantine the entire archive if the scan was started from the management console (as opposed to a manual scan started locally). If an email message is detected as infected inside the Outlook data file, the scan log will contain specific information as follows:
- When there is a file that can be disinfected, and attached directly to an email message, it is cleaned it up (by replacing the file content with zeroes at the byte level). The path of the PST archive is reported in the scan log (Ex: c:\Users\administrator\Desktop\Outlook1.pst).
- When there is a file that cannot be disinfected, and attached directly to the email message, it is not cleaned up. The path of the PST archive is reported in the scan log (Ex: c:\Users\administrator\Desktop\Outlook1.pst).
- When there is a file that can be disinfected, including those in a zip archive, it is cleaned up. The file is removed from the zip file, leaving an empty archive). The exact path for the file from its PST archive is reported in the scan log (Ex: C:\Users\administrator\Desktop\Outlook1.pst=>[Time: 2016=>03=>21 16:09:38][Subject: test in zip ]=>dialers1ecdc6b00f2021e94c6664c81597de86.zip=>dialers1ecdc6b00f2021e94c6664c81597de86).
- When there is a file that cannot be disinfected, including those in a zip archive, it is not cleaned up. The exact path for the file from its PST archive is reported in the scan log (Ex: C:\Users\administrator\Desktop\Outlook1.pst=>[Time: 2016=>03=>21 16:54:05][Subject: non dis in zip]=>009_non-dis.zip=>009_non-dis.dat).
- When files are in RAR archives, the files are not deleted.
- The behavior is similar whether the PST is in use in Outlook or not.
If a manual scan was started locally, then the local end-user is instructed to choose to Quarantine/Disinfect or Delete the file directly.
