I believe my HTC Thunderbolt may have spyware or some sort of virus. My applications (Pandora, Angry Birds..etc) have begun to show advertisements at the top and bottom while I'm in the app. Most of these ads are relevant to my location as well. I also found some advertisement pictures in my photo gallery that I did not put there. What is the best way to clear my phone of this virus. I've downloaded a few free apps that have not worked, and I'm reluctant to make a transaction on the market due to my phone having a virus. Would resetting my phone work? Any tips and advice would be appreciated.
