Which antivirus / mobile security do you use? I personally have been using Lookout Mobile Security. I have never had a problem with any of my apps, or system processes using it. Just curious what other ones are out there. Lookout is always running in my settings/apps/running services. I would imagine that any antivirus that is actively monitoring your system would have running services...but is there one out there that sits idle until it is called upon to do its job? Save a little battery juice?
