I am not a subject matter expert on viruses. So I must defer to those
who are. I am just trying to make a contribution. I hope I have used
a good method for notification of this issue. If I have put this in the
wrong place on this forum website, please tell me and I will do my
best to comply in the future.

I don't believe any action is necessary on my part to deal with this.
But I would be most appreciative if a knowledgeable moderator
could advise me about that.

Thank you for all that you do!

Hello Ted:

Thanks for using ClamWin!

You should upload all false positive detections, like that Brother printer file to Clam AV, starting at http://www.clamav.net/lang/en/sendvirus/ on the web. That web page has one link for false positive reports and another link for undetected virus reports. Clam AV furnishes the scan engine and signature database used by the ClamWin scanner, so they must take care of all signatures.

I reported the Brother file to Clam several days ago. They have not corrected it yet, so if you report it, that might help hurry things along. They might take a week or longer to get around to it. Most Clam AV signatures are now prepared automatically, but false positives must be worked manually, and, unfortunately, Clam AV does not have any full-time human sigmakers.

As for exploits, most AVs do not do that well at detecting them--especially in the early stages. I check any doubtful ClamWin detections on Jotti or Virus Total to see if Avast, Dr. Web and Nod32 detect them. These 3 AVs are usually pretty good at detecting exploits/adware, and I will believe a detection if they say so

Regards,
