Thanks stereo5 for your suggestion. This has been going on for a couple of weeks or so. The Malwarebytes pop up says I can exclude the webpage from being considered "riskware", and I have entered audiogon's webpage name and IP address using several different names/numbers and the pop up keeps happening. Like 10-12 times a minute. Maybe the "riskware" warning is true. I have been on audiogon and have had Malwarebytes forever. The warning says:
"Riskware, or “risky software,” describes legitimate software programs that contain loopholes or vulnerabilities that can be exploited by hackers for malicious purposes."
