New to forum - having the same issue as note below using Yahoo mail and trying to open legitimate Word attachments - any advice would be appreciated thanks.
- just happened todayYahoo mail has a PDF attachment from a valid source. This is a legitimate attachment that was expected from a bank, not just a random email.
Clicking on Open or Download causes Avast to show the red message and block a "malicious URL".
This has to be a false positive. Yahoo certifies they scanned the message with Norton. If I disable Avast, download the file and scan with avast, it is clean. This is happening with other pdf attachments on yahoo today as well.
