yes, it is false positive but maldet remove this file to quarantine.
I suggest to use Dans Tools compressor to prevent false positive alerts
This seem like a false positive Maldet alert .
I check all and this compressed javascript you get from online javascript compressors that replace names of functions and variables with short (one char) names.
But something in this method of compression like as Trojan pattern
Please use Dans Tools compressor for prevent false positive alerts and destroying or qarantining files
