Issue with Chrome

[Parrothead]

The default search engine keeps switching to Yahoo every time I close Chrome. How do I make it stop?

I also have weather channel desktop, and it wants to add the ask toolbar to Firefox.

I assume you have up to date anti virus/mallware killer software and have recently scanned your machine???

[Parrothead]

Yes. (Avast, super anti-spyware, and spybot s&d.)

I would try Malwarebytes Anti-Malware just to see if it finds anything else
