Hi, I have RSFirewall installed on a number of my Joomla sites and this morning all of them we're unavailable! I have checked the server logs and somehow all of the rsfirewall.php files in administrator/components/com_rsfirewall/helpers have been deleted hence none of the sites load correctly, has anyone else encountered this?

Hello,

We've had a similar report but with further information - and since you are hosted in UK as well, we believe this might be the same issue.
There was a server reboot at Heart Internet - after which the RSFirewall! helper PHP file was deleted. The only plausible explanation would be that the servers are running their own anti-virus/anti-trojan software that might have thought RSFirewall! was a trojan. The RSFirewall! helper file contains some signatures of known malware (by signatures I mean file names and small pieces of code that can be found in malwares, so that it can detect them on your website) and this could have triggered a false alert.
You should contact your hosting provider for further clarification.

Hi, I will forward this information onto them as it seems like a likely explanation as i'm also on heart internet, thanks

I received the following reply from Heart Internet:

"Our admins have advised us that they do have some new checking systems on the server which may have caused the problems with your sites. They are now looking into the systems to find a way to add an exception in for the module that you are using.

Our apologies for the inconvenience caused."
