I'm using HD7. I've been getting an automatic download of a "security_update.apk" No sure from where or why. I did receive an email from a friend with a link, and part of me thinks that it now might have been some spam and the link I clicked on resulted in some type of download. confusing part is the phone keep downloading it. I've not installed it. I've not caught wind of any update. And furthermore, since I'm running HD7, I did expect to receive such things. What I also dont get is what is triggering it to download again. I've power down/up the phone. So if its spam related, what is causing it to download more. Thoughts or suggestions on how to proceed?
