Worm, no Worm

Avast Free Antivirus / Premium Security

Hi all,
today I recieved a mail on my gmx-account. This mail was detected as SPAM by gmx and moved to the spam folder.
This mail had an attachment (file.exe). Usualy, the only thing to do with this mail is: delete it.
But i did a test to avast :wink: I saved this file.exe to my harddrive: No Alarm. I checked this file with avast: No Alarm.
I thougt, maybe it’s something knew.
So I moved the complete mail to inbox and got it with pop3: ALARM!!! Mydoom.L2 (Wrm)

Why didn’t Avast detect the Worm, when I was saving the file to Harddrive and checked it???

(Sorry for maybe some fault’s in english :wink: )

Thanks
Schwamml

Looks like this is caused by the setting you made in Avast.

Which are your resident task settings?
If you do not ask for scanning open/created/modified files… your mailbox won’t be scanned while being copied…

Hi,
i “tested” it again… and i think, gmx was deleting the worm… when i download the file from gmx direct to harddrive, the file is aboud 800 Byte. When i get the whole mail with pop3, the attachment is abaout 22 kByte.

Maybe this is a “secret” feature of gmx. I’ve got the free mail account, where no virus protection is included :wink:

I wonder if there’s some restriction on the size of attachment you can download with GMX and maybe it’s cutting off the attachment once you’ve downloaded the limit? You might want to check their FAQs because to me that seems more likely. I had a look at it but I’m afraid I don’t read German other than a few words here and there.
