This plugin contains a virus identified by wordfence – ss.js in the include file. Are these plugins the real thing or from unknown sites as they tend to add malware/virus into them.
Bruno, it is a false positive from Wordfence. ss.js is a JavaScript File. You can have a look yourself and double-check. No files from unknown sources here at GPLDL and all Gravity Forms addons come directly from Rocketgenius (the devs).
