Here is the official removal instruction from the developer of Toggle Toolbar for your reference, but to be honest I’m not quite sure it is gonna work since such virus toolbar is really hard to be removed completely.

For stubborn and malicious browser plug in I personally recommend you use Max Uninstaller to do the removal, this amazing tool just help me get rid of the disgusting searchuscom toolbar which I thought that I never get a chance to ditch it in my life. You can download the tool directly at its official website or you can visit itstutorial blog search for detailed instruction.

Or you can just uninstall the program from the control panel or scan for malware.

• Microsoft Safety Scanner
• MalwareBytes' Anti-Malware
• TDSSKiller - AntiRootkit Utility
• Hitman Pro
• ESET Online Scanner

SCAN with ALL.

Microsoft Security Essentials is a good permanent antivirus for Windows 7/Vista/XP if you don't already have one.
