Thank you for your replies.
Chrome gives me the following error message:
This type of file can harm your computer. Are you sure you want to download game-news.html. SAVE or DISCARD.
Firefox prompts for download or discard.
IE is working OK and displaying the .html pages automatically in the browser window.

perhaps something with the page is harmful

if you have an exe file on the page or something that prompts when the page comes up


I have seen this file type creates a lot of prompts and saying could be harmful


Even with screen savers and more things


Just have to be careful with your type of site
