Microsoft Defender Antivirus version and update cards functionality

Following are descriptions for the six cards that report about the version and update information for Microsoft Defender Antivirus engine, security intelligence, and platform components:

Full report

In any of the three version cards, select View full report to display the nine most recent Microsoft Defender Antivirus version reports for each of the three device types: Windows, Mac, and Linux; if fewer than nine exist, they're all shown. An Other category captures recent antivirus engine versions ranking tenth and below, if detected.

Shows the distribution of the top nine operating systems of each type

A primary benefit of the three version cards is that they provide quick indicators as to whether the most current versions of the antivirus engines, platforms, and security intelligence are being utilized. Coupled with the detailed information that is linked to the card, the versions cards become a powerful tool to check if versions are up to date and to gather information about individual computers, or groups of computers. Ideally, when you run these reports, they'll indicate that the most current antivirus versions are installed, as opposed to older versions. Use these reports to determine whether your organization is taking full advantage of the most current versions.

Antivirus mode card

Reports on how many devices in your organization – on the date indicated on the card – are in any of the following Microsoft Defender Antivirus modes:

value mode
0 Active
1 Passive
2 Disabled (uninstalled, disabled, or SideBySidePassive {also known as Low Periodic Scan})
3 Others (Not running, Unknown)
4 EDRBlocked

Shows filtering Microsoft Defender Antivirus modes

Following are descriptions for each mode:

  • Active mode - In active mode, Microsoft Defender Antivirus is used as the primary antivirus app on the device. Files are scanned, threats are remediated, and detected threats are listed in your organization's security reports and in your Windows Security app.
  • Passive mode - In passive mode, Microsoft Defender Antivirus isn't used as the primary antivirus app on the device. Files are scanned, and detected threats are reported, but threats aren't remediated by Microsoft Defender Antivirus. IMPORTANT: Microsoft Defender Antivirus can run in passive mode only on endpoints that are onboarded to Microsoft Defender for Endpoint. See Requirements for Microsoft Defender Antivirus to run in passive mode.
  • Disabled mode - synonymous with: uninstalled, disabled, sideBySidePassive, and Low Periodic Scan. When disabled, Microsoft Defender Antivirus isn't used. Files aren't scanned, and threats aren't remediated. In general, Microsoft doesn't recommend disabling or uninstalling Microsoft Defender Antivirus.
  • Others mode - Not running, Unknown
  • EDR in Block mode - In endpoint detection and response (EDR) blocked mode. See Endpoint detection and response in block mode

Devices that are in either passive, LPS, or Off present a potential security risk and should be investigated.

For details about LPS, see Use limited periodic scanning in Microsoft Defender Antivirus.

Recent antivirus scan results card

This card has two bars graphs showing all-up results for quick scans and full scans. In both graphs, the first bar indicates the completion rate for scans, and indicate Completed, Canceled, or Failed. The second bar in each section provides the error codes for failed scans. By scanning the Mode and Recent scan results columns, you can quickly identify devices that aren't in active antivirus scan mode, and devices that have failed or canceled recent antivirus scans. You can return to the report with this information and gather more details and security recommendations. If any error codes are reported in this card, there will be a link to learn more about error codes.

Up-to-date cards

The up-to-date cards show the up-to-date status for Antivirus engine, Antivirus platform, and Security intelligence update versions. There are three possible states: Up to date ('True'), out of date ('False'), and no data available ('Unknown').

Important

The logic used to make up-to-date determinations has recently been enhanced and simplified. The new behavior is documented in this section.

Definitions for Up to date, out of date, and no data available are provided for each card below.

Microsoft Defender Antivirus uses the additional criteria of "Signature refresh time" (the last time device communicated with up to date reports) to make up-to-date reports and determinations for engine, platform, and security intelligence updates.

The up-to-date status is automatically marked as "unknown" or "no data available" if the device hasn't communicated with reports for more than seven days (signature refresh time >7).

For more information about the aforementioned terms, refer back to the section: New Microsoft Defender Antivirus filter definitions

Note
