False positive malware report on website.

Hi,
I’m a website developer. There is a problem with false-positive malware report (or I think it’s false-positive and I’m wrong). Website is green on most of other online scanner or gray as ‘not scanned’, but still, Avast is blocking it. Is there any problem with the website I don’t know of? Can you check it for me and point what’s wrong? Or reassure me, that it is just Avast security mistake.
