E-mail attachment malware scan option

E-mail attachment malware scan option

Given the plethora of different AV and malware scanners on the market these days, I'm not sure whether or how easily this might be possible, but for a future version of Opera I'd really like the option of performing a direct malware scan of some attachment in my e-mail inbox via the drop-down function which currently only provides these 4 options: "open", "open with" (and a flyout to different applications, none of which is an AV or malware scanner that I've got installed), "save to download folder" and "save as". If an attachment IS identified as malware at that point, I could then delete it permanently without ever actually having it resident on my computer. As it now stands, I'd have to save it somewhere on a local drive (internal hard drive or external flash drive) and then scan it -- a step which I'd prefer to avoid entirely.

FWIW, I'm running Opera v10.53 on WinXP SP3 for 3 machines and Win7 Ultimate on a 4th; I use avast! as my resident AV scanner on all, but also run weekly full scans with avast!, Spybot, Malwarebytes, and Windows Defender on all the different machines as well (mostly in automated mode during an overnight period).

Interesting that no one else thought this was a worthwhile idea, yet in the past 3 days I've gotten more than 15 spam e-mails with a .ZIP attachment that is guaranteed to be a trojan or virus or rootkit or something bad that I can't otherwise confirm without actually downloading the file onto my computer's hard drive and testing it there. I'll take the safer route and simply mark them as "spam", move them to the trash bin, then empty the trash.

So, is it just completely impossible to set up an environment within Opera's mail system to allow for scans of e-mail attachments while they're still in the cloud, or merely difficult...?
