1) Scan your PC and check the details http://prntscr.com/i23bzy Looks like it’s not the site problem but local PC problem. Also, contact your hosting provider and ask to scan your site. Our theme does not have any malware code by default, you may download theme archive and check.
2) I see the Fatal error related to WPML http://prntscr.com/i23eys Contact WPML plugin to solve the problem, we are not authors of this plugin and provide support for issues related to our theme only.
1) Provide us with FTP access to your site. We’ll check. Also, contact your hosting provider and ask to scan your site. Maybe your site was hacked and the file was infected. In this case, you need to make sure that all the other files are ok and then replace the file on your site with the original file. If it does not help then provide FTP access to your site.
2) We also use WPML on this demo and don’t have problems http://8theme.com/demo/xstore/translation/
But if you check the fatal error you’ll see that problem appears in plugin files. You can also rename and disable plugin enabled default WP theme, then enable plugin again and check if you get the error again. If not then reply back to me.
