I haven't heard of it, but www.snopes.com is a good place to look for information about viruses and a good many other things. I didn't find anything about a virus attacking Norton and McAfee. There was a Symantec site, and I went to it but didn't find anything pertinent. You could contact Norton or McAfee if you have one or both of those. I'm sure their tech support could help you.
In the meantime by McAfee anti-virus and firewall seem to be doing the job. (Knock on wood? or is there a high-tech version when you aren't quite sure or are pretty ignorant?)
