pup.optional.winyahoo will not go away

[r49floyd]

Screen Shot of the MalwareBytes history file is attached.  I keep quarantining this threat but it keeps coming back every time MalwareB runs.   Apparently the quarantine is not working.  Just worried that something else might be going on.  Would like to make this go away?

Hello and

Please download Farbar Recovery Scan Tool and save it to your desktop.

Note: You need to run the version compatible with your system. If you are not sure which version applies to your system download both of them and try to run them.
Only one of them will run on your system, that will be the right version.

• Double-click to run it. When the tool opens click Yes to disclaimer.
• Press Scan button. button.

  

• It will make a log (FRST.txt) in the same directory the tool is run. Please attach it to your reply.
  

• The first time the tool is run, it makes also another log (Addition.txt). Please attach it to your reply.

Post its content into your next reply.

Allright!

Ran the above instructions and Zoek completed as described.  My system rebooted and I ran MalwareBytes ScanNow.  That came up empty!

 

I read the log zoek-results, but didn't get much from it.  So...a couple of questions please?

 

What do you think this pup.optional.winyahoo issue is all about?

What is it designed to do?

Any ideas on how it got there?

Is it really gone?

I'm happy to pay you for your time and trouble...please give me an indication of what you feel is a reasonable amount?

 

Thank You!   I appreciate your time and consideration!!

It is nothing but aggressive marketing from Yahoo. They probably have their affiliates that push their search engine in every possible way including malware. Probably not 100% true, but just my 2 cents.

Promote Yahoo.

Some malware families do this, you were infected with one named Conduit. They infected some Google Chrome components that store settings you should see when you open you browser.

Is it really gone?

Yup, it should be gone now. If not, please let me know.
