Very good point Spiritsongs, I must admit that when I upload samples to Jotti or VirusTotal I don't check and see if they are using the latest VPS or version, I have always assumed that they would be the latest. It is certainly something to watch. It would be different for us to check Jotti as it uses the Linux version of avast and that doesn't have the same version numbering.
I know they don't update immediately, but I thought it would be much quicker than that, 4.6.695 is quite old, so I wonder what the actual VPS is that is being used.
