Need to debug and make WordPress website mobile friendly

If you find our website, kloogame.com, through Google, you will see a message that says that this website might be hacked. We don't think it is. On Webmaster tools it identifies pages with script that causes the problem. So we would firstly like someone who is familiar with webmaster tools to deal with the "hacking" message.

Secondly webmaster tools says we don't have a mobile friendly site...we actually don't think it's too bad but we want to get it optimized.

It's a WordPress site and we use a theme called Nayama. We would like someone who can sort board of the issues for us asap. Please check out our website kloogame.com

Thanks for considering this project. We look forward to hearing from you.
