If Avast is reporting MAL:URL on the basis of the domain name being on a blacklist would you PLEASE, PLEASE display the name of the blacklist on which it was found?
When the Avast popup says "...because it was infected with URL:Mal", if it is really just reporting that the target website is being blocked because it is listed on a blacklist, then why not display "...because it is listed on the Barracuda blacklist" (or whatever blacklist)?
Or display "...because it is listed on the one or more blacklists" and list the blacklists in the "details" section.
If I have not understood URL:Mal then I apologize but it seems to get a lot of people running around wondering how to remove the "URL:Mal infection". Again, if URL:Mal is simply indicating a blacklist entry then calling it an infection causes a waste of time and effort.
