RE: Returned Mails

That's normal behavior for the Netsky virus. This virus uses all the email
adresses it can to replicate itself, generaly it uses the ones available in
the windows adress book, so if someone you know has your email in his/her
ad. Book, the virus will use it as sender id. IDS's, firewalls and corporate
anti virus usually notify the sender that he/she has a virus... It's whats's
happening to you. I get this all the time, and my pc is clean, I even get
this with an account I only use in Linux, so it's impossible it's infected.

Cheers,

R.

Hi,

This is probably a stupid question but I could do with some confirmation of
what I think is happening. I've been receiving a lot of 'return' emails
claiming they have been returned as I have a virus. Example below:


A virus was found in a message sent by this account.

--- Scan information follows ---

Result: Virus Detected
Virus Name: W32.Netsky.C () mm
File Attachment: posting.txt.com
Attachment Status: deleted

--- Original message information follows ---

I have up to now guessed these were down to 'someone' else's pc infected
with netsky or mydoom but after a lull I have been bombarded with loads of
such mails over the course of the day.

I would just like some reassurance that this is indeed due to other people
infected boxes rather mine. I have of course run several full system scans
with Norton av with the latest definitions etc and do use a firewall, Spybot
etc.

I've googled and this starts to confirm my suspicions but isn't authorative.

Thanks in advance,

Guru
