It's good that you're moving the design along and trying other approaches but I still think you have a bit more sketching to do. When I first looked at you last version I straight away thought "that mouse pointer is screaming out to be made into the V" - and I am not saying that would make a great logo, just my initial impression.
I actually think you were on to the start of something with your earlier V microbug thing. Anyway that said look around on Google Images, searchy by "software engineering" and see what images come up, if anything inspires you. Because you're dealing with an IT subject it is very easy (and a bit lazy if I'm honest) to think "oo microchips, circuit boards, components" - a great logo comes from research, imagination, inspiration and sketching.
Keep going!
