Runtime error 216 at

Hello Christina,
Could you please let us know whether you have received the error message while opening Windows-based program or during the startup of your PC?
Thank you.

The net says this is a backdoor Trojan, and the message has come up at start up for the past 2 days. I immediately run a full deep scan, but AVG isn't finding and removing it. What else can I do?

It is when I switch on my computer first thing in the morning.
