Whilst most of these html files will have been in your temporary internet files folder, some could well have been in other locations. But there is a lessor risk of harm at the lose of an html file than having opted to delete sat and .exe file.
So it really is a lesson in exercising, first do no harm, don’t delete. Move to chest and investigate, but if there are multiple detections you should be looking at what files are being detected for a common file type and malware name. Then you should consider stopping the scan and investigate what you know about the existing detections.
Check the avast forums, avast blog, etc. and see if there is anything listed that day.
