Uptobox and HTML:Script-inf suspicion

Hi,

since yesterday, Avast Web Agent is refusing access to uptobox file download.
It says : hxtps://uptobox.com/… [L] HTML:Script-inf [Susp]
I wonder if it’s a false positive. Uptobox seems to be a serious site to me.
I would not like to disable avast on the whole site, seems dangerous, no ?
Is it possible to disable only one virus detection ?
Is it possible to block only the suspicious call to an external site ?

Thanks for your help.
