OK so google informed me that my website had been compromised and had Malware so they were showing a warning to people coming to my website through Chrome.
I have found the Malware it looked something like this
It was in Miscellaneous Scripts section in General/ Design tab.
I have removed it but how do I prevent it from happening again, do the hackers have a back door? What do I do.
I thought I was doing everything right.
I have a CDN, blocked access to downloader, installed the patches and have strong passwords.
Can anyone else give me some more information?
