I have been running SG for many months and during that time there have been no updates at all. With this in mind, just how much value is the signature based aspect of SG - is it even worth running at all? I realise that there are other functions to SG, such as browser hijack warnings, but this protection is available from other products. Does the download protection aspect of SG achieve sufficient results to render it worth continuing to run? One has to balance resource utilization against benefits gained. What do others feel?
