CA eTrust has a utility called “SigCheck.exe”.  It’s purpose is to display the current version of the eTrust anti-virus definition which is on the local PC.

From a command line, you run it like this:

Sigcheck.exe Vet

Sigcheck will then return the command signature version

Sigcheck Vet version: 37.0.9825
(this was an eTrust AV version from 3 March 2012)

If you were to include the running of Sigcheck.exe into a “PC Health Check” type script, you’d have a quick way of determining whether anti-virus updates were reaching your fleet of PCs.
