Does the linux agent not allow you to manage dat updates/virus scan settings?
I took a quick gander, got it installed and reporting and also installed virusScan, now I believe this is purely on-demand but system properties on the host in ePO does not show VS being installed.
there are 2 virusscans for linux. one is an ondemand scanner that only scans on demand and has no epo manageability at all. The other is/was called Linuxshield which is a true on access scanner for linux. That does have an epo agent and is manageable via epo like the regular VS for windows.
Sounds like you are talking about VirusScan Command Line Scanner for Unix.
Current version is 6.0.3 and it is not ePO-managed in any way.
Current version of LinuxShield is V1.6, and as previously mentioned this can be fully managed by ePO 4.5.
