"How to stop a mass mailer"?

Question

I am getting "mail not deliverable and mail sent from my email address on yahooo that I did not send .
How do I stop it?

Answer 1

Run a virus scan on your PC. But chances are, the virus that is causing all these emails to be sent (and the rejects to come back to you) is not on your PC.

When a mass-mailing virus infects a PC, it scans the infected PC for any email addresses stored there in address books, documents, cached web pages, etc. It then randomly pairs up the found addresses to be the TO and the FROM addresses and generates all the bogus emails. So it's very possible that the infected machine is NOT your computer but instead belongs to someone who happens to have your email address stored in their computer.

Run a virus scan, make sure your definitions are up to date, use all the common-sense security precautions all the time, and ignore any more of these emails you get. Sooner or later the owner of the infected PC will figure things out, fix their computer and the phantom Undeliverable (NDR) messages will stop.

and if you have a wireless router follow these tips,


1. Use WPA encryption (WPA-PSK) it's less crackable then WEP.

2. Make a passphrase that is upper & lower case and has some numbers thrown in there as well, again harder to crack.
some like mAkE1t5eCurE0rel53 and as long as possible.

3. Use MAC access control so only you or authorized PC's can connect (even if you do have encryption turned on)

4. Turn off DHCP use static addresses.

5. Turn off SSID (and change it) unless your card really needs it (some do)

6. Change username/password of access unit front end

7. Ensure you have the usual firewall enabled on your PC.

8. Paranoia rules, turn WLAN off if your not using it :)

i'm not sure, but when you find out, let me know. i'm recieving a lot of spam/virus stuff...not to mention it says it's from MY address...which of course i didn't send it. what's even WORSE is i looked down and saw that it read "lesbianpics" and i'm thinking "my goodness, i hope no one gets this and thinks i sent it!!!"

how do you pick the best answer for something like this? lol. :)

Answer 5

You opened that virus...didn't you? I'm serious. There's one going around in yahoo mail. Something about a graphic site. Don't remember the name. Check your antivirus providers website.

EDIT: Actually a worm...not virus
