Hi

When I open Chrome Yahoo comes up by default. I have looked in all the usual places and - nothing!

How do I get rid of this barnacle?

Try resetting Google Chrome. There may be other adware/ malware at play. Use the programs below to find and remove them.

Look in your Add/ Remove listing of programs and uninstall ALL Yahoo listings.

 

Google Chrome gives you the option to reset your browser settings in one easy click. In some cases, programs that you install can change your Chrome settings without your knowledge. You may see additional extensions and toolbars or a different search engine. Resetting your browser settings will reset the unwanted changes caused by installing other programs. However, your saved bookmarks and passwords will not be cleared or changed.

Reset your browser settings
  1. In the top-right corner of the browser window, click the Chrome menu
  2. Select Settings.
  3. At the bottom, click Show advanced settings.
  4. Under the section "Reset settings,” click Reset settings.
  5. In the dialog that appears, click Reset.

Use CCleaner to remove Temporary files, program caches, cookies, logs, etc. Use the Default settings. No need to use the

Registry Cleaning Tool...risky. Pay close attention while installing and UNcheck offers of toolbars....especially Google.

After install, open CCleaner and run by clicking on the Run Cleaner button in the bottom right corner.

CCleaner - PC Optimization and Cleaning - Free Download

 

Download Malwarebytes' Anti-Malware from Here

Double-click mbam-setup-2.X.X.XXXX.exe to install the application (X's are the current version number).

  • Make sure a checkmark is placed next to Launch Malwarebytes' Anti-Malware, then click Finish.
  • Once MBAM opens, when it says Your databases are out of date, click the Fix Now button.
  • Click the Settings tab at the top, and then in the left column, select Detections and Protections, and if not already checked place a checkmark in the selection box for Scan for rootkits.
  • Click the Scan tab at the top of the program window, select Threat Scan and click the Scan Now button.
  • If you receive a message that updates are available, click the Update Now button (the update will be downloaded, installed, and the scan will start).
  • The scan may take some time to finish,so please be patient.
  • If potential threats are detected, ensure that Quarantine is selected as the Action for all the listed items, and click the Apply Actions button.
  • While still on the Scan tab, click the link for View detailed log, and in the window that opens click the Export button, select Text file (*.txt), and save the log to your Desktop.
  • The log is automatically saved by MBAM and can also be viewed by clicking the History tab and then selecting Application Logs.

POST THE LOG FOR  REVIEW.

 

Download Junkware Removal Tool to your desktop.

  • Shut down your protection software now to avoid potential conflicts.
  • Run the tool by double-clicking it. If you are using Windows Vista, 7, or 8; instead of double-clicking, right-mouse click JRT.exe and select "Run as Administrator".
  • The tool will open and start scanning your system.
  • Please be patient as this can take a while to complete depending on your system's specifications.
  • On completion, a log (JRT.txt) is saved to your desktop and will automatically open.
  • Post the contents of JRT.txt into your next message.

Hold down Control and click on this link to open ESET OnlineScan in a new window. (Eset can take more than an hour to run so plan accordingly)

  • Click the esetonlinebtn.png button.
  • For alternate browsers only: (Microsoft Internet Explorer users can skip these steps)
  • Click on esetsmartinstaller_enu.exe to download the ESET Smart Installer. Save it to your desktop.
  • Double click on the esetsmartinstaller_enu.png icon on your desktop.
  • Check "YES, I accept the Terms of Use."
  • Click the Start button.
  • Accept any security warnings from your browser.
  • Under scan settings, check "Scan Archives" and "Remove found threats"
  • Click Advanced settings and select the following:
  • Scan potentially unwanted applications
  • Scan for potentially unsafe applications
  • Enable Anti-Stealth technology
  • ESET will then download updates for itself, install itself, and begin scanning your computer. Please be patient as this can take some time.
  • When the scan completes, click List Threats
  • Click Export, and save the file to your desktop using a unique name, such as ESETScan. Include the contents of this report in your next reply.
  • Click the Back button.
  • Click the Finish button.
  • NOTE:Sometimes if ESET finds no infections it will not create a log.

I have the same problem. It started about a week ago. It appears only in Chrome browser.

I did everything that's been described -above- by "buddy215" (reset my Chrome browser settings, used CCleaner & Malwarebytes' Anti-Malware & Junkware Removal Tool & ESET OnlineScan).
I've cleaned all the threats (not all of them were real threats, but I cleaned them just to be sure that I've done everything described) that were found in my laptop, but the problem is still here... :(
 
Any other suggestions?

Welcome to BC....since the OP hasn't responded back no further advice was given.

 

You didn't mention running AdwCleaner so if you haven't, do that.

Download AdwCleaner by Xplode onto your desktop.

  • Close all open programs and internet browsers.
  • Double click on adwcleaner.exe to run the tool.
  • Click on Scan button.
  • When the scan has finished click on Clean button.
  • Your computer will be rebooted automatically. A text file will open after the restart.
  • Please post the contents of that logfile with your next reply.
  • You can find the logfile at C:\AdwCleaner[S1].txt as well.

 

Open CCleaner and click on Tools. Choose Startups. On that page you will see a list of Windows Startups and at the top tabs for each browser and Scheduled Tasks.

At the bottom right of that page you will see a button when clicked will allow you to Copy and Paste the list of Windows Startups and Scheduled Tasks into your next

post. Please do that.

 

Open CCleaner and click on Tools. Choose Uninstall. On that page you will see a list of programs installed on your computer and at the bottom right of that page you

will see a button when clicked will allow you to Copy and Paste that list in your next post. Please do that.

update:
I did what was  suggested by "buddy215", but the problem was still there.

The strange thing is that some days later it disappeared like... magic :wizardball: , since I've done nothing else!

Yahoo Toolbar Hijack 09-9-2105
 
Preamble:
Home brew desktop PC running Win7 Home Premium 64 bit with 120 GB SSD and 1TB HDD originally built in 2011.
Had BSOD problems, so bought brand new SSD (250GB) and new 2TB HDD.
Removed existing SSD and HDD, installed SSD only, reinstalled Win7 OS.
Still had BSOD, so on advice from BleepingComputer Kernal Dump Expert (usasma) tweaked BIOS to disable USB3.0.
This solved BSOD, but while downloading SSD testing utility (CrystalDiskMark5), inadvertantly picked up Yahoo Browser Hijacker.
 
 
Work thus far:
 
1. Tried resetting Chrome settings.
2. Ran CCleaner
3. Ran Malwarebytes - removed lots of PUP with yahoo and yonto files
4. Ran Junkware Removal - nothing found, but log is attached
5. Ran AdwCleaner - nothing found
6. CCleaner Startup and Install logs attached
7. Ran ESET Online scanner - log attached.

Thanks,

notthebomba...it would be best if you copied and pasted logs into a new topic...

I also suggest you look in your list of installed programs and uninstall all Yahoo related items listed there.
