WordPress site redirects to another link when clicked First time

I am experiencing website redirection on my website when clicked through Google search results only for the new user.

For example:

1. Go to Google.com (in a NEW window where there is no previous history of cflowapps.com)
2. Search for “Cflow”
3. Click on www.cflowapps.com
4. Click anywhere on the page, it redirects to spam site

This happens only for the first time.
