html script.inf found by avast while opening excelforum, from firefox latest edition

Hi,

I am a loving reader of the site. While try to find solution to some excel problems, the first cite, i always choose is your forum. But when i click for the first time mentioning the problem with excelforum, clicking www.excelfourm leads to avast blocking the site, by displaying the connection to the server was reset and firefox comes with Problem loading page and the avast popup saying that it has blocked html script.inf, and if i choose to open again. the same problem loading appears.
Now, i either access this site using the replies to the previous thread received in my email. I also address this issue with avast. Please, look in to the matter as i think, that it is a genuine site and i want it to be ever to be like that.
