System update 12.3.11 credit card info

[MichaelBo]

I recieved an Update today with the above mentioned number. Before I can finish the Update it asks for my Credit Card Information. Is this normal Practice? I'm afraid, that my Phone has been affected by Virus. Please help

Software updates pushed out by phone manufacturers are always free.
You are been scammed if you proceed any further.

I agree with @exsanguinator, this is totally a scam. Some app you installed lately might be causing these messages to appear. If you can't figure that app out, then I'd strongly recommend that you perform a software repair using Xperia Companion. This will do a clean installation of the latest firmware and will also wipe your internal memory. Follow the steps given in the blue link, do not connect your phone until prompted to press volume down while plugging USB cable.

You can first backup using Xperia Companion, but don't include "Apps" or "Settings" in the backup.
