Like many others we rely on multiple AntiVirus tools and one of them is the ubiquitous ClamAV on our Linux hosting servers. Earlier today we started being hammered with ClamAV notices of viruses being identified. Some research later and we are confident the ClamAV Archive.Test.Agent2-9953724-0 is a False Positive.
(quarantined to /home/quarantine/cxsuser/client-account/backup_2022-06-25-0330_Clientaccount_f4f78444ae93-themes.zip.1656132445_1) ClamAV detected virus = [Archive.Test.Agent2-9953724-0]
Various internet sources confirmed that ClamAV had indeed released an update signature file which included a ‘Test’ signature, namely ‘Archive.Test.Agent2-9953724-0’. A subsequent update, released within 24 hours addressed the false positive and, hopefully, prevents any future signature file from containing Test signatures.
