What is the difference between a “Signature” and a “Version” and why are “new signatures” considered safe?
A version of Warden is a specific set of functionality, such as scanning routines. There is one version of Warden active at any given point in time, for each set of servers (US, EU, etc). To make life more difficult for hackers, Warden is a bit dynamic — there are hundreds of slightly different copies of any given version of Warden, which may be sent to your computer for usage. The different copies contain the same functionality, but with slight modifications in the code that would have no effect on the functionality. Each of these copies is identified by its signature.
