Thank you Eddy and Tech. Eddy, you are right. I did a search for "ATMENUXX.HLP" and it does have something to do with ATI (video card, I assume?) files.
Tech, when you say "Behavior Blockers" are you referring to something in avast! Pro? (I'm using the home version.) But if you're referring to the "Blocker" tab of the Resident Protection (Standard Shield), then I can tell you that I've left all the settings at their defaults.
Something just came to me about my original post, so I'd like to ask about it (no major issue, just curious): When the message said Write file: C:... SYSTEM\ATMENUXX.HLP, [/color][/b] I assumed that some outside process was trying to write to (modify) the file ATMENUXX.HLP.[/b] But does it actually mean that the file ATMENUXX.HLP.[/b] is (somehow) trying to write something to my computer? (Or "install" itself or "add" itself during startup, which is when I get that message?)
Thanks all.
