Hello grungegrunge and Welcome -
We have found that spigot is now downloaded with IObit programs secretly.
Are you aware of having any IObit programs, like Advanced System Care and others installed ??
If you do have these installed, please remove them and use their uninstaller program.
Now try to Reset your home page(s) to what they were.
If you still have problems start with avast! cleanup tool to remove their toolbar.
Now - Download Autoruns to your desktop
Double click on Autoruns exe.
Allow the program to fully populate (this will take a few minutes)
Go > File > Save > Save as Autoruns.txt > File Type > All Files
Save to Desktop
Copy and Paste the Autoruns.txt back here
From here I can help you delete any remaining entry that may cause problems -
Thank You -
