Yahoo! ID field is converting user ID to numbers

The Yahoo! ID field is converting your username to numeric values and you cannot sign in because of this.

If numbers appear when you try to enter your Yahoo! ID into Yahoo! Messenger, please check if a keystroke protection application is installed on your computer. Here's how to check:

1. On your keyboard, hold down the Windows key and press the R key. This opens the "Run" command.
   
   • Type: appwiz.cpl
2.    Then click OK. This opens "Add or Remove Programs," or "Programs and Features."
3.  Review the list of programs for a keystroke protection application.

If found, try temporarily disabling or uninstalling this software and then testing Yahoo! Messenger. If you are able to sign in after uninstalling or disabling the software we suggest consulting the software developer for further protection.

If you did not find a keystroke protection application on your computer please follow these steps:

1. On your keyboard, hold down the Windows key and press the R key. This opens the "Run" command.
2. Type "msinfo32" and click OK. This opens "System Information."
3. To save the log file, click the File menu and select Export...
4. In the left column, click on Desktop.
5. Type "Yahoo!" in the File Name field.
6. Click Save.
7. Once the progress bar is complete and disappears, close "System Information."
8. Right-click the "Yahoo!.txt" file and select "Send To", then select "Compressed (zipped) Folder."

After, click on Contact Yahoo! and fill out the form. While filling out the form, upload the zip file to the appropriate field.
