Finally got worried enough to install antivirus today. Specifically, Antivirus Free by droidSecurity, Inc. Just checked my battery use and it's used 41% of my battery today, compared to 16% for the display. I can only assume that it's doing the same thing to my memory. So I find myself thinking I don't really need it seeing as I have never heard of anyone getting a virus. Do I really need antivirus? Have there been horror stories already?
