My website was hacked a few months ago and I found some malicious codes in file manager and I deleted many of them but few of them are not deleting they keep coming back in file manager how do I delete it?
A lot of times this is appended to valid files if you're not able to find the source it'll keep coming back. You'll want to request your host to assist you with this and scan the files in your account to help identify malicious code inside them.
