Virus definitions not updating

[forti_fan]

Hi, On my fortigate 80c with firmware version 4.0 MR2 and a valid license the virus definition are not updating any more. On the dashboard it shows: AV Definitions 18.00509 (Updated 2013-04-23). I also tried these commands from the knowledgebase with no success: # exe ping update.fortiguard.net # diag test update info # dia deb en # dia deb app update 255 # exec update-now (Wait two minutes while the update completes before continuing) # dia deb reset # dia deb disable Help would be appreciated. Thanks!

Thanks! I must be blind. I have downloaded the virus definitions for the fortigate 80c and OS Version v4.00_MR2_P3 and tried to manually install the package. But is says: ERROR Firewall has all the updates found in the given file.

Perhaps this is a browser cache issue? Have you tried another browser? Have you tried hard refreshing the page? (hold down the >SHIFT< key while clicking refresh will force the entire page to be read again)

Here is a picture of my dashboard.

The License Information lists " extend set" in use. Perhaps try switching back to the " normal" set.

The ' normal' set is the first line. The dates are usually the same.

Your AV signature comes from the future. Current is 17.00864, that' s what you could download. As long as the installed DB has a higher version no. there won' t be any updates. Dunno how that happened to you. You can get rid of that DB by reloading the firmware. Signatures included in firmware loads usually are pretty old. You should be able to update then after kicking off the update process.

If the definitions are from the future i dont have to worry about future viruses :). I will try to reinstall the firmware and restart the update process. Thanks!

There was a command available to allow downgrading AV defs. I cannot locate it.

Hello, Fortinet started in march rolling out AV signature v18.xyz for certain devices. Back in april we had the same problem - a faulty signature v18.xyz which prefented further updates and no possibility to manually download a valid signature package from the download page (there are only signatures v17.xyz). We contacted tech support, they supplied us a valid v18 signature and the problem was solved. Sincerely harald
