Trojan virus from iPhone USB driver?

Earlier i plugged my iPhone 5 into my computer and it didn't connect, I then got a warning message from AVG saying their is a possible threat, so I scanned my entire computer and It found a couple of virus so I got rid of them and then I tried plugging in my phone again and nothing happened again so I went to my device settings and it said that It needed troubleshooting so I did and it then said their was no driver so I pressed apply fix and it searched for the driver and then installed it but as soon as it finished I got the same massage again saying that their is a possible threat detected. It seems the virus is coming from the USB driver for my iPhone 5, why is that? Can anyone help please I don't no what to do, I can't connect my phone to my computer because of it please help!

Maybe it's a false alarm.

Download the norton app and scan your phone… My guess is that you have some autorun malware… I'm assuming they have it for iphones since it is readily available for free in the google play store.
