Simple theme and storefront?

Hello all,
Anyone can suggest nice them and simple storefront?

It’s for Domain portfolio

I had it setup already using Woocommerce and Storefront, but something created link to
https://websanalytic.com/web/analityc.php and slowing my site tremendously. I disabled all plugins and changed to 20/20 theme. The bad slowing link finally disappeared, but I have to start all over again. I have choice, but your suggestions are most welcome.

Thank you all in advance
