Html script inf Gzip

Hello
What to do when Avast reports a Malware on my website www.libertas7.es. Checked the site and reports that there is no problem. My webhost checked and reported that there is no problem. I’m using Avast on my computer and when I do a test registration on my website, Avast reports the following:

File name: http://www.libertas7.es
Malware name: HTML:Script-inf

How do I repair or remove this?

Please help?
