How do i stop a hacker that got into my Yahoo mail?

Question

For weeks now i've been getting notifications sent from the mail sub system telling me my mail was undeliverable, sometimes 10 a day. I assume that someone has hacked into my email account and is spamming. I have the latest updated antivirus/spyware protection and it's not picking anything up, how do i get rid of this hacker?

Thanks for your input.

I have changed my password yesterday and checked my email today and there is new spam that has been returned as before.

Answer 1

The mails returned to your email is not something to worry about, its a server gltich and nothing else, but to assure your account security I'd recommend you to change your password periodically, at least once in 15 days, use a sign in seal to secure your yahoo inbox and account.

Answer 2

Hotmail is really bad for this. Gmail is better. So is yahoo mail. Anyway, change your permissions so that, for the moment, only those you approve may send you mail. It is likely not your account that is causing this - I would suspect that someone you sent an email to has a virus that is mass sending out email using that person's address book as the sender names. Run a virus scan on your own system just in case, but really there isn't much you can do if the virus is coming from someone else other than close out the email account and start again.

Answer 3

it sounds like you got a worm that is sending spam or somthing , check your ports go to shields up and try house call for a web virus scan if your infected its bypassing your antivirus and your just wasting time if you find open ports and any viruses contact yahoo or your internet service provider after being sure youve been invaded the only thing to realy be sure is to repartitione and format your hard drive then do a fresh install of your operating system . web based proxys can help as well as getting a diferent browser .i sugest firefox or opra :D good luck i hope you get things straight.

Answer 4

Chances are her account hadn't been hacked. It is probably a virus that uses contacts list to send out spam. Run a virus scan.

Trojan Removal Procedure for Windows XP

Removing infections from your computer is never as easy as aquiring them. Malware infections are not meant to be removed, so, it takes TIME and PATIENCE to get rid of them. ONLY RESORT TO A REFORMAT AFTER ALL ELSE FAILS TO REMOVE THE INFECTION.

This procedure works for all Malware. Replace the Ewido and AdAware SE programs with any AntiVirus or AntiSpy program you choose.


Download and Update Ewido (now called the AVG Antispyware). Do not run:

http://www.ewido.net/en/download/...

Download AdAware SE and update. Do the setup. Do not run:

http://www.filehippo.com/download_ad-aware/

AdAware SE Setup:

1. Select "use custom scanning options" then select "customize". Make sure the following options are enabled: "scan within archives," "scan active processes," "scan registry," "deep scan registry," "scan my IE favorites for banned URLs," "scan my Hosts file."

2. Select the "tweak" option. Under "scanning engine," make sure "unload recognized processes and modules during scan" is enabled. Enable "scan registry for all users instead of current users."

3. Under "cleaning engine" turn on "always try to unload modules…," "during removal unload explorer and IE if necessary," "let windows remove files in use at next restart," and "delete quarantined items after restoring."

4. Use the "select drives and folders to scan" option to ensure that your entire hard drive is scanned (if you have more than one hard drive, scan all of them (of course, do not include floppy and CD/DVD).


TEMPORARILY SHOW HIDDEN FILES AND FOLDERS.

1. Click Start, and then click Control Panel.

2. Click Appearance and Themes, and then click Folder Options.

3. On the View tab, under Hidden files and folders, click "Show hidden files and folders", and clear(uncheck) the "Hide protected operating system files" check box.

IMPORTANT: Files are hidden by Windows for a very good reason. It is not wise to experiment with these files. Unfortunately, to successfully remove modern spyware we must turn this protection off temporarily. Please turn the protection back on when you have finished cleaning your system.


EMPTY INTERNET EXPLORER BROWSER CACHE:

1. On the Internet Explorer Tools menu, click Internet Options.

2. On the General tab, in the Temporary Internet Files section, click the Delete Files button. Select the Delete all offline content check box in the confirmation dialogue box that appears, click OK. Click OK again.

RESTART IN SAFE MODE:

To do this you need to hold down or repeatedly tap the F8 key while the computer is booting (when the computer is displaying a black screen with white text). When the boot menu appears, use your keyboard arrows to select "Safe Mode."

Safe Mode can look quite ugly. The color may look bad, and all of your desktop icons will be very large. This is normal.



START THE SCAN WITH ADAWARE SE. THEN DO IT WITH EWIDO.

NOTE: Let AdAware complete its scan. Sometimes AdAware will be unable to remove everything that it finds and will prompt to be allowed to try again after restarting. If that happens, when the scan finishes restart immediately and allow the scan to finish.


When the scan and removal are completed REBOOT COMPUTER. This will restart you in normal mode. DON'T FORGET TO RESET HIDDEN FILES AND FOLDERS.


NEW RESTORE POINT:

The RESTORE POINTS may be infected with the Malware and cannot be used.

HERE'S HOW:

1. Click Start, and then click Control Panel.

2. Click Performance and Maintenance, click System, and then click on the System Restore tab.

3. Select the Turn Off System Restore check box, click Apply, then restart your computer.

4. Return to the System Restore Tab and turn System Restore back on.


TO SET A NEW RESTORE POINT:

1. Click the Start button.

2. Point to Programs, then navigate to Accessories, then System Tools, then click System Restore.

3. Choose Create a restore point, and then click Next.

4. In the Restore point description box, type a name for your restore point, and then click Next.

5. Click OK.

NOTE: If you are using Windows XP Service Pack 2 (SP2) and are unable to access the Internet after removing Malware, there is a command that may fix the problem. It works by resetting the winsock catalogue. Click on Start, then Run and type CMD in the box. Click OK. Type "netsh winsock reset" (no quotes)into the DOS window that appears.


ADDITION INFORMATION ABOUT TROJANS:

There are Trojans that fall into the Smitfraud family. These require the use of a specialized program for removal. Here are two sites that specialize in removing these:
