Downloaded app Anitvirus a couple weeks ago and had no issue until 2 day ago. I went to go to my maps link and that was it. The phone went crazy. I could not maks calls and all my messages came four or five times. I went to the Verizon Store and they asked me if I had that app because I was the third in two days. I took it off and all is well. SO, If YOU HAVE DOWNLOADED ANTIVRUS APP ON MOTOROLA DROID REMOVE BEFORE YOU HAVE THE ISSUES I HAD!!!!
