Avast 6.0.1367 Network Shield suddenly started blocking Yahoo mail attachments from downloading even though some of the attachments had been successfully downloaded before.
Yahoo’s built-in Norton indicates no virus found in attachment. If Avast is disabled, the suspect file downloaded, then scanned with Avast, no virus is found.
Hello,
it was problem on our side not on user’s site.
We receive many alerts from yahoo emails and unfortunately, even when we trying whitelist those pages really fast, sometimes we block those pages.
Sorry for your inconvenience.
