I believe that I could have picked up a virus is there a way I can check
I highly doubt you picked up a virus. The only way to install code is via the Windows Store which all apps are reviewed by Microsoft before releasing to the public to download.
What makes you think you picked up a virus?
To answer your question, no there is no anti-virus protection for Windows Phone.
dg19713,Top notch inquiry! And to be honest, unless you picked up a third party application, we do not sell anti-virus support. However, you can check out your phone's app marketplace to see what's available.EvanO_VZWFollow us on Twitter @VZWSupport
