Do you know any scanning service for our website or hosting account ? I mean, check whether the files are compromised or not. Even paid ones are ok.
Abhi this shouldn't be limited to simply scanning looking for vulnerabilities in the file system itself. Many more harmful vulnerabilities exist in the web server configuration, poorly configured SSL ciphers, weak certificate configurations etc...
They used to give a free scan option. I don't see that now. Go through their website and see whether there is anything you can use.
I will check that. In Sucuri scan is there. I found it
