Hi.
Sorry to hijack this thread. I have the same problem. SEO Spam.
Sucuri Online shows the site as infected and I received an email from Google saying the site was hacked.
I did a complete scan with the plugin and it detected two threats which were quarantined.
I did a rescan. Sucuri still shows site as infected. Other scanners show site as clean but there are almost 100 outbound links from the site to websites
https://shopgiayluoi.com/
https://blog.thoitrangf5.vn
https://thoitrangf5.vn etc which are spam links inserted into the code.
Btw, the site url is https://www.hometoolsworld.com
Thank you for reading and your help.
