Need to remove YouTube Downloader and its crass Yahoo toolbar.

Download the latest version of MGtools and save it to your root folder. Run the exe and attach the resultant log --- C:\MGLogs.zip.

 

It this the Youtube downloader:
YTD Toolbar v6.3 ??

I am not seeing it in any of your logs. What have you tried to do to remove it? What browser is it in?

Use windows explorer to find and delete:
C:\Users\ordi\AppData\Roaming\Microsoft\Windows\Templates\B21UFLfk3

Now copy just the bold text below to notepad (Do not include any space above the word REGEDIT). Save it as fixME.reg to your desktop. Be sure the "Save as" type is set to "all files" Once you have saved it double click it and allow it to merge with the registry.

Make sure that you tell me if you receive a success message about adding the above
to the registry. If you do not get a success message, it definitely did not work.

 

Please download ComboFix to your desktop. Turn off any AV software you have before you run it. Attach the log when finished. Do not do anything while it is running or it may stall the program.

 

You can try using Revo Uninstaller to remove that program.

 

Go to the C:\MGtools folder and find the MGclean.bat file. Double click on this file to run this cleanup program that will remove files and folders
related to MGtools and some other items from our cleaning procedures.
