Yes, a trojan is generally a bad thing.
You need to get rid of it.

Multiple AV and malware scans, with different tools.

Define "bad".

If you like to make your machine participate in a bot net, then it might be a good first step to let the trojan run wild.

If the question is should you panic? Most likely not. But panic is rarely a good option anyways. But you should not ignore the error or pretend it is NOT a thing. You better start scrubbing you files. Run MalwareBytes for starters.
