Aluria Spyware Scanner found 3 instances of Browser Buddy and 1 of IST Toolbar. I deleted the Browser Buddy (but don't know if there are remnants left behind) and before I delete IST Toolbar I need to ask a question. IST Toolbar is in WIndows>System>chktrust.exe. That chktrust.exe is a MS icon so I don't know if I can safely delete it or not.
Help. Please.
