I moved the topic into the forum. Please use the report center only for finished reports. Requests or issues with Lansweeper should be posted here.
Please find a KB article
here which describes how Lansweeper scans data about anti-virus software. You might need to add the software you are using under
Configuration\Anti-Virus and/or rebuild the antivirus WMI class on the affected target computer. This is described in the article.
