I liked it at first, but then started to get an error screen on shutdown, telling that a program was still running. I found out on another forum that others had experienced this problem. Uninstalling it put thing right.
I much prefer the free version of this. click here
I like the realtime shield, if you tick all the boxes, it can be a bit obtrusive, but it keeps a close eye on what's going on and gives you the chance to stop untoward activity before it can really start. You do need to read the warning popups though, as always clicking yes on autopilot just to get it out of the way circumvents its protection.
