Malware

The plugin only inserts the codes you configure (these codes may also load or insert some other code).

You can use debugging functions to diagnose insertions:

Basically you need to disable all blocks and then enable one by one to figure out which code is responsible for what you believe is malware:

You need to provide some data if you would like us to check your website – please clearly describe the issue or code to check:
