"delete global quest search application I am getting the message pop up on my screen about every thirty seconds. How do I delete it? Do you want the application “GlobalQuestSearch” to accept incoming network connections?"

Remove this Login Item:

Another thought: Remove this login item - To do so, boot into Safe Mode [Hold Down: shift key upon boot] - login items will not open upon login in. So, if this is a login item, these messages, would stop popping up. Then, remove it, by probably dragging it to the Trash from the Applications window, and then emptying the Trash.

So, remove this and all unknown items as such and then restart the Mac, seeing if it/they no longer popup at login.

To Remove Them:

1. Go To: System Preferences
2. Select: Users & Groups
3. Click: This user name
4. Click: “Login Items”
5. Select: Uneeded items.
6. Click: “-“ button
