The question can’t be answered as there is no information to answer it.
Avast can’t corrupt the file as it isn’t working with the live file, but a copy of it in its c:\windows\temp_avast_ folder. The files after having been scanned in this folder are cleared, so even if there was a corrupt file it isn’t on the site and again why only this site.
This is why I still stick with my original supposition that this isn’t on your system as you think it is and you supposedly fixed it (but didn’t say what you fixed ?).
