I just connected my new Arduino Uno and am going through the setup guides. I loaded the example code "blink" and went to upload it and it says error, can't access com3 port. avrdude: ser_open(): can't open device "\.\COM3": Access is denied.
I'm using windows 10, I've been through the troubleshooting guide and the only thing in the access section seems to me to be applicable is the fact I have Kaspersky installed which might act as a firewall... I turned it off and still no joy. I've tried other USB ports and restarting. I've tried reinstalling IDE and updating the drivers... Any help would be appreciated.
