Unwanted redirection to google

A sample in this page (see the SUEDE or SATIN blue buttons):

Hi there,

It seems the site is being 301 redirected either from apache i.e htaccess or php so you will need to check both php files and htaccess.

Thanks.

I checked htaccess, but what do you mean for php? Which file?
Thank you,
Ugo

Found!
It was Semalt Redirect Manager.
many thanks!
