C:\Program Files\Common Files\Symantec Shared\VirusDefs excessive size

This issue has been solved. See solution.

I know that this has been discussed ad nauseam, but I can't seem to solve my issue.  My C:\Program Files\Common Files\Symantec Shared\VirusDefs folder has consumed 18.7 GB of the 30 GB HDD on my server.  None of the folders are in the tmp* or *tmp format.  Almost all of them are in the numeric format of YYYYMMDD.###.

Unfortunately, we're still running Symantec Client Security v9.0.1 and this server is acting as a parent.  I'm in the middle of upgrading hardware and software across the board and have upgraded a number of systems to Endpoint Protection 11.0, but I need to keep this old system limping along for a while if possible.

At this point, these Virus Defs have almost filled the disk on this server.  The only other thing running is the operating system itself.  Is there any way for me to purge some of them to free up some disk space?

the previous definitions are not getting purged,
You can delete all the revision and then update your server with latest definitions
stop symantec sav service
Delete all the numbered folders inside symantec shared
drop the xdb file or run the liveupdate, this should free up the space

Please follow this document...

How to rebuild virus definitions on Symantec AntiVirus (SAV) client

I appreciate your advice.  I read through the instructions and I don't have an 'Update Cache' tab.  I do have the folders listed.  Can I still follow the rest of instructions safely?

Thanks again,

What's the version of your LiveUpdate?

SAV 9.x is the EOL product.

You need to delet the folders with older dates ( folder names)

Keep the recent  YYYYMMDD.###. folders and delete the other folders

Thanks to all of you that provided input.  Unfortunately, the suggestions you provided didn't work.  However, I noticed in the Event Log that after trying the instructions above, SAV was failing to start.  I hadn't seen that previously.  I found instructions at that gave some additional instructions.  I followed those instructions, and finally got to a point of step #8, which was looking into the usage.dat file.  I cleared out all but the most recent entry.  From there, I restarted SAV and it started successfully.  It also began LiveUpdate on it's own and appears to have the most current virus definition.

Thanks to everyone for your help!
