My Chrome on Mac (with Mac OS Sierra) always starts with feed.snowbitt.com when I run it I always get redirected to site feed.snowbitt.com when I run my Chrome. I tried to:
-Delete Chrome from computer, and reinstall it. Didn' work.
-Clear all my content, browsing history from Chrome. Didn't work.
-I tried some free antivirus programs to scan my cimputer. Didn't work.

What else can I do?
Go to Chrome > Preferences... by pressing ⌘, or by typing chrome://settings/ into the Address Bar.

Under the On start-up settings, make sure you have selected Open the New Tab page and not some specific page, which in your case is: "feed.snowbitt.com"
