here is my symptom (reading the forum, i think the symptom is fairly commonly seen)

my yahoo email account was sending out unsolicited mass emails with NO subject but a line of URL in the text.


this started a few days ago. password stays the same (but i will change it soon).
i first ran microsoft security essentials and it picked up several malicious infections.
but after clearing them up, two days later my yahoo was again sending out emails. (password unchanged)

some of my internet conditions
i usually use chrome to access my yahoo.
i tried to update my java (as i read it somewhere that chrome needs certain java version to run smoothly) but somehow couldn't complete the process (is this a sign of infection or hacking ??)
i access the internet through a wireless router at home (rented - sharing with three other people)
i recently started seeing an new icon on my taskbar, which says "windows media player library sharing" - it asks me if i allow my housemate's computer to play content from my windows media player library. either that it did not exist before or that i haven't yet noticed until now, i can't be sure.

do not know where else to look for other signs of infection/hacking. i am a newbie so please be forgiving if i did not provide enough info. thank you very much

Hi Seraphin,

A few questions, if I might.

And let me encourage the Admins to step in here if any of the questions are inappropriate or better not handled to a public forum.

Please _DO NOT_ change _any_settings or delete _any_ information on your computer based upon my note. Also please do not post any information that might be individually or uniquely identifiable, such as pc or network settings or log files without going through an Admin!

Is the domain name on the email link the same as the set listed in the thread "Yahoo Account Compromised"?

Have you taken any steps, such as those mentioned in the Yahoo sticky note above, to fix the Yahoo acount?

When you ran MS Security essentials do you remember any of the malware it identified or cleared? Do you think you could find the log it created for that run? (Please don't post it here unless requested by an admin.)

Do you have any info on the properties of that new icon? (Please don't post the actual settings here unless requested by an admin.)

Have you set any system protections to prevent your pc from being accessed by any of the other pc's on the wireless network? (Please don't post the actual settings here unless requested by an admin.)

And do you know if the wireless network has any protections in place to prevent network spoofing, "Man in the Middle" attacks, etc?(Please don't post the settings here unless requested by an admin.)

sorry that i do not understand lots of what you asked, but below is the list of what MS essential found - not sure when they infected my laptop though

i will re-read your thread and respond to it later

as they all contain the word "Java" and somehow i can't update my Java, i have been wondering if my old Java is the culprit for my vulnerability


TrojanDownloader: Java/OpenConnection.EM
Exploit:Java/CVE-2008-5353.O
Trojan:Java/Mugademel.A
Exploit:Java/CVE-2009-3867.IJ
Exploit:Java/CVE-2008-5353.QV

Perform the following tasks and post the logs of each if you can.

Malwarebytes Anti-Malware

Please download Malwarebytes Anti-Malware and save it to your desktop.Download Link 1
Download Link 2
MBAM may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you. Temporarily disable such programs or permit them to allow the changes.

  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
    For instructions with screenshots, please refer to the How to use Malwarebytes' Anti-Malware Guide.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
MBAM will automatically start and you will be asked to update the program before performing a scan.
  • If an update is found, the program will automatically update itself. Press the OK button to close that box and continue.
  • If you encounter any problems while downloading the definition updates, manually download them from here and just double-click on mbam-rules.exe to install.
On the Scanner tab:
  • Make sure the "Perform Full Scan" option is selected.
  • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
Back at the main Scanner screen:
  • Click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad.
  • The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  • Copy and paste the contents of that report in your next reply. Be sure to post the complete log to include the top portion which shows MBAM's database version and your operating system.
  • Exit MBAM when done.
Note: If MBAM encounters a file that is difficult to remove, you will be asked to reboot your computer so MBAM can proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.


SUPERAntiSpyware:

Please download and scan with SUPERAntiSpyware Free

  • Double-click SUPERAntiSypware.exe and use the default settings for installation.
  • An icon will be created on your desktop. Double-click that icon to launch the program.
  • If it will not start, go to Start > All Prgrams > SUPERAntiSpyware and click on Alternate Start.
  • If asked to update the program definitions, click "Yes". If not, update the definitions before scanning by selecting "Check for Updates". (If you encounter any problems while downloading the updates, manually download them from here. Double-click on the hyperlink for Download Installer and save SASDEFINITIONS.EXE to your desktop. Then double-click on SASDEFINITIONS.EXE to install the definitions.)
  • In the Main Menu, click the Preferences... button.
  • Click the "General and Startup" tab, and under Start-up Options, make sure "Start SUPERAntiSpyware when Windows starts" box is unchecked.
  • Click the "Scanning Control" tab, and under Scanner Options, make sure the following are checked (leave all others unchecked):
    • Close browsers before scanning.
    • Scan for tracking cookies.
    • Terminate memory threats before quarantining.
  • Click the "Close" button to leave the control center screen and exit the program.
  • Do not run a scan just yet.
Reboot your computer in "Safe Mode" using the F8 method. To do this, restart your computer and after hearing your computer beep once during startup (but before the Windows icon appears) press the F8 key repeatedly. A menu will appear with several options. Use the arrow keys to navigate and select the option to run Windows in "Safe Mode".

Scan with SUPERAntiSpyware as follows:
  • Launch the program and back on the main screen, under "Scan for Harmful Software" click Scan your computer.
  • On the left, make sure you check C:\Fixed Drive.
  • On the right, under "Complete Scan", choose Perform Complete Scan and click "Next".
  • After the scan is complete, a Scan Summary box will appear with potentially harmful items that were detected. Click "OK".
  • Make sure everything has a checkmark next to it and click "Next".
  • A notification will appear that "Quarantine and Removal is Complete". Click "OK" and then click the "Finish" button to return to the main menu.
  • If asked if you want to reboot, click "Yes" and reboot normally.
  • To retrieve the removal information after reboot, launch SUPERAntispyware again.
    • Click Preferences, then click the Statistics/Logs tab.
    • Under Scanner Logs, double-click SUPERAntiSpyware Scan Log.
    • If there are several logs, click the current dated log and press View log. A text file will open in your default text editor.
    • Please copy and paste the Scan Log results in your next reply.
  • Click Close to exit the program.
If you have a problem downloading, installing or getting SAS to run, try downloading and using the SUPERAntiSpyware Portable Scanner instead. Save the randomly named file (i.e. SAS_1710895.COM) to a usb drive or CD and transfer to the infected computer. Then double-click on it to launch and scan. The file is randomly named to help keep malware from blocking the scanner.

Now GMER

Please download GMER from one of the following locations and save it to your desktop:

  • Main Mirror
    This version will download a randomly named file (Recommended)
  • Zipped Mirror
    This version will download a zip file you will need to extract first. If you use this mirror, please extract the zip file to your desktop.
  • Disconnect from the Internet and close all running programs.
  • Temporarily disable any real-time active protection so your security programs will not conflict with gmer's driver.
  • Double-click on the randomly named GMER file (i.e. n7gmo46c.exe) and allow the gmer.sys driver to load if asked.
  • Note: If you downloaded the zipped version, extract the file to its own folder such as C:\gmer and then double-click on gmer.exe.

    Posted Image
  • GMER will open to the Rootkit/Malware tab and perform an automatic Full Scan when first run. (do not use the computer while the scan is in progress)
  • If you receive a WARNING!!! about rootkit activity and are asked to fully scan your system...click NO.
  • Now click the Scan button. If you see a rootkit warning window, click OK.
  • When the scan is finished, click the Save... button to save the scan results to your Desktop. Save the file as gmer.log.
  • Click the Copy button and paste the results into your next reply.
  • Exit GMER and be sure to re-enable your anti-virus, Firewall and any other security programs you had disabled.
-- If you encounter any problems, try running GMER in safe mode.
-- If GMER crashes or keeps resulting in a BSODs, uncheck Devices on the right side before scanning

SAS

does pick up lots of Adwares. but no spyware, malware, trojans, worms ... etc.

ran it twice in two consecutive days and picked up Adwares twice. seems like every time i used internet, some adwares will be registered (?) onto my system ??

Gmer

finds NO change was made (i think this is what it said at the end of the scan).
