Hi,

 

- What are you referring to "toolbar logo has is not there"?
- Which FIXIT have you tried to resolve this issue?
- Have you made any changes on the computer prior to this issue?
 
Method 1: I would suggest you to keep the computer in clean boot mode and check if the issue persists.
A clean boot helps to verify if any third party application services or startup item is causing this issue.
You may refer the following KB article to set the computer in clean boot:

Note: After the trouble shooting steps, refer to Step 7 from the clean boot link to set the computer back to normal start up mode.
 
Method 2: I would suggest you to uninstall and reinstall the Microsoft Security Essentials from the link and check if the issue persists.
