Your version of Yahoo search is out of date.

Recommended Posts

Hi 

for a few months now a message pops up on my computer 

'Update Required  
Your version of Yahoo  search is out of date. 
There is a newer and improved version available with the fresh and intuitive Chromium browser.  
By clicking "OK" you agree to Install Chromium browser as your default browser,install our Desktop search bar, 
set Yahoo provided search as your default search, homepage and new tab on all of your compatible browsers. '

I don't have Yahoo search so I'm assuming it's malware. There also isn't an X to close the window when it pops up so I usually right-click on it on the task bar and click close. 

I have tried running a Windows Defender full scan which finds nothing, I have tried running a Malwarebytes scan which finds nothing and I have tried running an AdwCleaner scan which finds things every time but the pop up still occurs even after it has removed whatever it has found. 

I haven't downloaded or installed anything new or suspicious looking so I don't know how it got into my system. 

Once I have finished a scan I can't tell whether the malware removals have worked or not because the pop up occurs infrequently and randomly. 

What can I do?

I downloaded the  Farbar Recovery Scan Tool as instructed however when I run it it claims there's an update, it installs the update, says that it's ready to use, only to update again etc. this loops endlessly no matter what I do. I have to right click on it in the system tray and Exit to make it stop.

Hello Sirithaniel and welcome to Malwarebytes,

Rename FRST64.exe to betaFRST64.exe or if the 32 bit version FRST.exe to betaFRST.exe it should run now, if so post the two produced log..

Thank you,

Kevin

Download attached fixlist.txt file (end of reply) and save it to the Desktop, or the folder you saved FRST into.
NOTE. It's important that both FRST and fixlist.txt are in the same location or the fix will not work.

Open FRST and press the Fix button just once and wait.
The tool will make a log on the Desktop (Fixlog.txt) or the folder it was ran from. Please post it to your reply.

Next,

Please open Malwarebytes Anti-Malware.
 
  • On the Settings tab > Detection and Protection sub tab, Detection Options, tick the box "Scan for rootkits".
  • Under Non-Malware Protection sub tab Change PUP and PUM entries to Treat detections as Malware
  • Click on the Scan tab, then click on Scan Now >> . If an update is available, click the Update Now button.
  • A Threat Scan will begin.
  • When the Scan is complete Apply Actions to any found entries.
  • Wait for the prompt to restart the computer to appear (if applicable), then click on Yes.
  • After the restart once you are back at your desktop, open MBAM once more.


To get the log from Malwarebytes do the following:
 
  • Click on the History tab > Application Logs.
  • Double click on the Scan log which shows the Date and time of the scan just performed.
  • Click Export > From export you have three options:
    Copy to Clipboard - if seleted right click to your reply and select "Paste" log will be pasted to your reply
    Text file (*.txt) - if selected you will have to name the file and save to a place of choice, recommend "Desktop" then attach to reply
    XML file (*.xml) - if selected you will have to name the file and save to a place of choice, recommend "Desktop" then attach to reply
     
  • Please use "Copy to Clipboard, then Right click to your reply > select "Paste" that will copy the log to your reply…


Next,

Please download Junkware Removal Tool to your desktop.
 
  • Shut down your protection software now to avoid potential conflicts. (re-enable when done)
  • 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.


Next,

Download Sophos Free Virus Removal Tool and save it to your desktop.

If your security alerts to this scan either accept the alert or turn off your security to allow Sophos to run and complete.....
 
  • Double click the icon and select Run
  • Click Next
  • Select I accept the terms in this license agreement, then click Next twice
  • Click Install
  • Click Finish to launch the program
  • Once the virus database has been updated click Start Scanning
  • If any threats are found click Details, then View log file... (bottom left hand corner)
  • Copy and paste the results in your reply
  • Close the Notepad document, close the Threat Details screen, then click Start cleanup
  • Click Exit to close the program
  • If no threats were found please confirm that result....


Let me see those logs, also tell me if there are any remaining issues or concerns...

Thank you,

Kevin....

Hi

 

Thank you for all your help.

It's difficult to say since it's been an intermittent problem and pop up.

Is there anything else I should download and run or any other scans I could do to confirm clean bill of health?

Sophos AV scan is very thorough and would normally locate anything we may have missed with prior scans... Maybe use your for 24 hours, comeback and give an update. If all is ok we can clean up. If there are still issues or concerns then we have another check of your system....

I assume all is ok as you do not give any feedback, run the following to clean up:

Download "Delfix by Xplode" and save it to your desktop.

Or use the following if first link is down:

"Delfix link mirror"

If your security program alerts to Delfix either, accept the alert or turn your security off.

Double Click to start the program. If you are using Vista or higher, please right-click and choose run as administrator

Make Sure the following items are checked:

 
  • Remove disinfection tools <----- this will remove tools we have used.
  • Purge System Restore <--- this will remove all previous and possibly exploited restore points, a new point relative to system status at present will be created.
  • Reset system settings <--- this will reset any system settings back to default that were changed either by us during cleansing or malware/infection


Now click on "Run" and wait patiently until the tool has completed.

The tool will create a log when it has completed. We don't need you to post this.

Any remnant files/logs from tools we have used can be deleted…

Next,

Read the following links to fully understand PC Security and Best Practices, you may find them useful....
