How can we scan a joomla site for malware or virus online in the server itself? any extension(open source)? Thanks & regards Sony
i think for scan your site you can look tools at this link sectools.org/web-scanners.html, and for protect your joomla site, you can use any extensions in this link extensions.joomla.org/extensions/access-a-security/site-security, cmiiw
I think having server with antivirus option is the best solution...on the other hand you can always do it locally On your back up maybe...
-download all files to pc for backup- backup your "template folder", "configuration.php" and erase all files from host than upload new Joomla files except "installation" folder while scan your template folder manually, it has max. 10 files upload your scanned template and cfg file finally change your ftp pass
You may be able to find an online virus scan plug in on the joomla site. Check out NinjaSecurity or Php Anti-Virus. I would post the links but I don't have access to live links yet.
