Yes, they could be...
Iframe is a command (tag) that could be at your computer (local iframe tag) or remote (remote iframe tag).
It's a feature of the HTML part check of avast. Some viruses make use of bugs in some mail programs (especially unsecured MS Outlook and Outlook Express) that make it possible to start the virus merely by viewing the message in preview pane. avast! checks whether the HTML code of the message does not contain a tag enabling such a trick. If yes, the warning message will be displayed.

DHM100: in heuristic module of avast! (Outlook Provider and Internet Mail Provider) you can customize iframe manner. Whether check local or/and remote iframe. And for remote iframe you can define set of "safe" urls. It's good in case that you receive mails with remote iframe tag and you are sure, that it's OK, so avast! will not warn you.
