That's funny, and it reminds me of something we discovered too. We use bugsnag on many of our client web apps to catch javascript runtime errors and with one of our apps we frequently come across problems that reference javascript functions and variables that aren't ours. Sometimes it turns out to be a benign plugin, but in many of these cases it is a known virus or dangerous browser plugin that is trying to log keystrokes, mine crypto, extract banking info, etc. We have gotten to the point where we can often tell them which virus they have, how we know, and include removal instructions. Our app is very expensive so most customers are people who need our tools and use the app everyday, which means we can often tell them when they got the virus too. It's way out of scope for our role in their life, so it's a little bizarre for everyone involved, but the customers seem to appreciate it at least.
