That is a tricky one. Because those files are protected, you can't delete them with a batch file.
What I would recommend is going onto the core and go to the ..\managementsuite\ldlogon\antivirus8\Win\bases8\bases\blst and remove all those files. Then download them all again by .
Perhaps one of those is the corrupted file and updating them on the core will allow the clients to update the version they have.
If that doesn't work, try removing AV. Make sure the files are removed from the client side and then reinstall AV.
The same issue in LANDESK 2016. Any ideas?
Here is information on the particular message you are seeing including how to correct it:
It looks like you may have reached out to support on this issue already though. I show a resolution indicating:
We managed to resolve the issue by applying cloned AV settings (I copied the current settings without changes, apply them & run AV update task). Afterwords we applied original settings, run vulscan, AV worked perfectly.
Please let us know if the above corrected the issue, or if you are still experiencing issues with this.
