Yes, when you have the paid version, you can edit the trusted vendors list, so crucial software on your PC can be auto-allowed. All software not updating through its own executable (e.g. like Microsoft Office and Chrome), can be assigned a default BLOCK rule. So you can auto-allow publisher Microsoft but deny all Office executables suspicious behaviour. This sort of changes the behavior of Spyshelter from a system wide HIPS to a vulnarable process suspicious behavior blocker with zero pop-ups, because the SPECIFIC PROCESSES (AUTO) BLOCK RULES have higher priority than than the SYSTEM WIDE AUTO ALLOW PUBISHER RULES.
