For some reason, my gmail acct automatically sends a pornogrphc virus with a .scr file together with a pornogrphc picture named life.jpg. It also automatically renames the subject of the email per yahoogroup.

BADLY NEED YOUR HELP

Do you see these emails in the "sent mail" folder when you check on the Web?
Do you have a resident firewall?
How did you determine Gmail was sending something like this out?

I ask these questions because the source of the emails might not even be from your computer or your Gmail account. Many times, viruses will use Email addresses they find on OTHER computers they have infected, to send out Emails to everyone in the address book of the infected computer.
In this case, it is not you sending them out, but an infected computer using your Email address to masquerade its actual source.

John

Thanks for your immediate reply.


Do you see these emails in the "sent mail" folder when you check on the Web?
* Yes, sometimes I do, and sometimes I don't.. kinda weird really..

Do you have a resident firewall?
* None that I know of.

How did you determine Gmail was sending something like this out?
* I knew it because some of my friends (who are members of the yahoogroup) received the email and they immediately informed me..


Need your help. Thanks.

To continue:

1. You should immediately install a resident firewall if you don't have one. Either ZoneAlarm or SygatePersonal Firewall are free and will provide an additional layer of protection for your computer.

2. Has anyone OUTSIDE the membership of the YahooGroup received this Email from you? I presume we are talking about only ONE email and not multiple examples with different subjects/texts here, though your response about some do and some don't confuses me.

3. Are you 100 percent sure that any of these Emails supposedly sent by you show up in your Gmail sent box?

4. Can I assume you have run a thorough hard drive scan with your Anti-virus?

I am still not convinced that your computer (certainly it would not come from Gmail or this would be pandemic amongst its users) is the culprit. A firewall should prevent anything untoward leaving your computer, so future instances (even if your computer is a fault) will not occur.
I belong to many Yahoo groups, and in almost every instance where this has happened, it has been the result of someone else's computer stealing the sender address and using it to send malware to the group.

John
