You can check this 2 links for the last 2 files:
If you check the links, I think there is not really a virus in the files. Before we publish a girc version, check all the files. However some stupid virus scanners find something. A reason for this can be a file that can check and display your hardware in girc. So the result "Misc/Motherboardmonitor" is correct. But it's not dangerous because it just displays your hardware in girc.
How to solve this: Change the settings in your virus scanner so it ignores the file. Or write a mail to the virus scanner support team. Maybe they can help you. I cannot do anything from my side.
