My experienced for that crypter :
~ the crypter not FUD after 1 week released date.
~ fast update version (no longer FUD / UD quality)
Thus i not interest the version4.x . Just wait the new major version for analysis (5.0 , 6.0 ....)By the way. What version is doesn't matter ,unless you know how to refud with your own, your server longer fud then others.
Video Prove Chrome Crypter 2.0 have been REFUD can bypass avira runtime as well
p/s. The clean version for new chrome crypter 4.3 ...4.x will come out with sharecash,fileice (survey link). You may get it on your own
