This is what fascinates me about VS and probably why I kept uninstalling it then 'missing' it and reinstalling it. The sense of security it gives you is palpable. You just know it's working hard for you. Also the icon, interface, help popup and website are all very well done. The DETAILED settings give the impression a lot of thought and testing went into it.
A bit of history on myself in regards to these types of apps... Many eons ago I was project lead/evangelist on what may have been the first Windows whitelisting application - that was at Stardock. I viewed it as groundbreaking in the age when viruses weren't nearly as big of a threat but I felt they would become one. Unfortunately the product didn't get approval for further development beyond beta - it was a lot like VS.. My second work was done as an engineer on a very early whitelisting program called 'SafeNSec', which exists today for govt., military, embedded system (like ATM) protection.. So there is a good chance when you use an ATM it's got a bit of my DNA in it.
What keeps me using VS is the 'what was that?' crap it prevents.. Many of us, probably a LOT of people here always want insight as to what their systems are doing, what is running and what is happening that they can't see.. It drives people like me insane and even moreso since the Hacker Deterrent fiasco where Trend itself was injected by something..
So day to day, VS 'flashes', your system keeps running fine.. Then deep in your brain it nags you.. 'Why did it flash?' and what was stopped that had absolutely zero impact on the function of my system? Then you look at the logs and think .. 'So, what the hell was XYZ doing running in a command prompt, powershell or whatever?'... The inevitable thought of 'glad VS is there' keeps coming up in your head to the point if you ever uninstall it you will constantly wonder what the hell you are missing!
So when VS flashes every 15 minutes on my wife's laptop and I find a Lenovo Management Program attempting to execute NETSH and other crap you know it's good to have around because really, why would a dumb hotkey manager need to probe my network every 15 minutes and look at all of the TCP/UDP connections? It doesn't and it shouldn't and Lenovo has been busted loading malware onto their systems from the factory..
It's good to have VS on your side IMO.
