Re: KLEZ virus signatures

We have been looking into the possibility of adding a signature for the Klez variants. The obvious trouble for these types of signatures is the mutating behaviour of the virus. We believe that the best solution for dealing with these types of security issues is a strong, regularly updated anti-virus installation, especially at the site mail gateway. Even if an IDS signature were in place, these virii often generate so many alarms that is not feasiable to track them all. So, sometimes, we decide not to include a signature for these types of attacks.
