We have a large array of websites (mostly WordPress) hosted on many different servers and most of them are shared servers.
From server logs we can see many unexpected/malicious attempts to hack our websites. We already have File Monitoring in place. Now we wish to remotely scan our web server files using a open source or Free AV like ClamAV.
May anyone suggest how can we scan new files on web server using FTP access? Is this possible with any free AV and if not what are the best possible alternates available?
Also suggest what are the best open source/free AV available which make sense for website malware scanning because most of AV products are targeted for desktop scanning.
I know there is an PHP extension available for ClamAV but we cannot put AV on these servers hence that option is not available.
