My Wordpress site was hacked

I found out my site was hacked when I visited a page and it redirected me to another site. When I went back to the page everything was fine. when i visited from my phone it redirected. When I went back on my phone it was fine. The hack redirects on the first visit from a device and ip address and does not after that. Is there software to help check my site for redirections.

Maybe you can PM someone your URL and they can check if it redirects on the first visit.

Also make sure to check your .htaccess file (done via FTP) and see if there is any nefarious plugin installed by the hacker.
