The free version of Sucuri is not a server side scanner but I see no outward signs of hacking.
If you want to be double sure that you don't have any malware, add Wordfence and Anti-Malware by ELI. Go to Wordfence Options > Scans to include and check all the options in this section and run a scan.
If Wordfence finds no malware, then load Anti-Malware by ELI. I does require that you register your site and download a current malware profile but it is a free plugin. Then run a full scan. It's important to focus on anything that the plugin calls malware or quarantines.
Let us know what you find.
