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 itā€™s something knew.
So I moved the complete mail to inbox and got it with pop3: ALARM!!! Mydoom.L2 (Wrm)

Why didnā€™t Avast detect the Worm, when I was saving the file to Harddrive and checked it???

(Sorry for maybe some faultā€™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 filesā€¦ your mailbox wonā€™t be scanned while being copiedā€¦

Hi,
i ā€œtestedā€ it againā€¦ and i think, gmx was deleting the wormā€¦ 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 ā€œsecretā€ feature of gmx. Iā€™ve got the free mail account, where no virus protection is included :wink:

I wonder if thereā€™s some restriction on the size of attachment you can download with GMX and maybe itā€™s cutting off the attachment once youā€™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 Iā€™m afraid I donā€™t read German other than a few words here and there.
