I have two employees that reported a warning on both AVG and Avast which I'm pretty sure is a false positive. Below are the two versions in question:
AVG Technologies Software Version: 23.5.3286 (build 23.5.8195.786) on Windows 10, Version 22H2
Avast Security 15.6.0. Free version on macOS 12.0.1
Both reported this error: "HTML:Iframe-inf [Susp]"
Is there any way to get more information on why it thinks there is something malicious? The intranet site that triggered the warning it's a ticketing system. There is an iframe for the message editor, and one for file uploads. But they have been running those programs for a year or more and the software for the ticketing system hasn't changed in about the same time. I'm thinking maybe a bad update went out recently?
