I was like the OP and installed dozens and dozens of apps within a week or two after receiving my Incredible. I thought about an AV app and installed Lookout! as it was free. After reinventing my Incredible phone quite a few times buy rooting, uninstalling, changing this and that, I finally went back to a stock phone, reinstalled much of my apps but left out the AV app. I am more discreet on what I install and many of the apps I've installed have never giving me any problems that would make me feel I need an AV app. I've slowed way down on what I install and I am very careful on what I download to my Incredible. So far, so good after almost a year of ownership.
