Running Report for assets with no virus protection

[Budman007]

When we run a report for assets with no virus protection, it shows 8-10 with no protection and over 400 protected. However, most of the ones it shows without protection, does have the same virus protection as the 400 that shows in the report as protected. Could it be older OS on those assets showing no protection? Screenshots attached

In general, when Lansweeper scans your assets, the antivirus information is being retrieved in two ways: 

• By scanning the WMI class AntiVirusProduct.
• By comparing the installed software with the list of known antivirus software found in the web console under Software\Anti-Virus Settings

For Windows Server operating systems specifically, the AntiVirusProduct WMI class does not exist and the antivirus information can only be retrieved from the second option listed above. More information on how Lansweeper scans antivirus information can be found in the following article: https://www.lansweeper.com/knowledgebase/managing-anti-virus-software-reports/

With this in mind, if an asset is returning the 'No antivirus installed' message, this could be explained by one of the following: 

• The antivirus software information is not listed in the WMI class AntiVirusProduct.
• The antivirus software is not listed under Software\Anti-Virus Settings. Adding the software to this list and rescanning the asset should solve this. Make sure to use the name as it's listed in the software tab of the asset. You can also use the % operator to catch any variations, e.g. Mcafee%.  
• The asset hasn't been rescanned recently. Manually rescan the problem computer by hitting the 'rescan asset' button in the left-hand pane of its asset page.
