After I boot within 10 mins disk usage approaches 1GB without me using the PC.
I have traced the issue to the ‘nnn.cav’ file sitting in the …\cis\signatures folder. Within 10 mins of booting two new cav files have been created in this folder. The first made within 5mins, then another (new filename) and the first file is deleted. File size is nearly 500MB. So that’s writing 1GB of data for a small <10MB downloaded signature update.
This is repeatable, the signature database .cav file is always recreated, create date = modified date.
What can I do to make CIS update the signature database instead of recreating it each time.
Also how can I instruct CIS to only do one update in the option setting of 6 hour signature update period, instead of two within a few minutes.
I don’t think slow or corrupt download is likely as my internet connection is good and reliable.
I’m concerned about the unnecessary SSD writes caused by recreating the .cav file rather than updating it. I mean, I assume it is a database file and can be updated rather than recreate a whole new file with each virus signature update.
Thank you for reporting.
CIS will download complete base if (existed base version on user machine - max server available DB) >150 else it will download only incremental updates. How often do you see the CIS downloading repeated base? Could you please provide us the Log details of Tasks. ie., Tasks-> Advanced Tasks-> View Logs → Tasks for further investigation of the issue.
Have a nice day!
