In regards to the double post, what browser are you using?
Search is your friend in this community. There are a couple of posts in the Android Apps section of this community that discuss antivirus applications as well as mentions of bad Apps that were removed from the Android Market.
As for what I use for antivirus applications, I have used both Lookout and AVG Antivirus on my phones. No big complaints for either of them. Norton has one. McAfee does too. Kapersky or something like it has an android application as well.
I'm most definitely NOT a VZW employee. If a post answered your question, please mark it as the answer.
