Thanks for the response.
I have changed the settings from their default to prevent the ‘open file for writing’ check, so I don’t expect it to question the action again.
For clarification, I can answer your questions…
I run Windows 98SE. The warning message appears about 30 seconds after boot-up, just as the skin files in AVAST4\Data\Skin\ are scanned. The message says an attempt to write to AVAST4\SETUP\SETIFACE.DLL has been intercepted. I still don’t know why this is necessary, but it happens without fail everytime I log on (perhaps not now with the options changed).
I hope this information is useful to someone. I hope it isn’t an as-yet-undi scovered virus or similar.
Thanks again,
Richard
