BTW am not sure if it is possible but would be helpful if there were a maintained list of all suspect plist files ...
That's a great idea but it's impracticable. Certain variants recycle the dozen or so examples listed in that User Tip, or they attempt to leverage legitimate file names but with creative misspellings. Others use randomly chosen dictionary words, or just a bunch of randomly generated alphanumeric characters. Some generate literally hundreds of such files in a desperate, pathetic attempt to overwhelm the client.
If there is any key "takeaway" it's that Mac users should have at least a passing familiarity with the contents of those three folders. That should not be a difficult task since they normally contain very few files, if they contain any at all.
And it just goes without saying, "think before you click". Nothing gets installed on a Mac without your consent. Adware gets installed by leveraging the desire to get something for nothing. Click here, it's free! That's how it works.
Nothing is free. This site is "free" only because you already paid for it by purchasing a Mac.
