Fortinet detecting NSIS

Fortinet 3.14.0.0 2008.05.10 Adware/Vapsup.0408

I'd let them know, but I don't know how to contact them :/. But please, someone do

Got the new version, now Fortinet doesn't detect it, but Prevx1 does

Prevx1 V2 2008.05.10 Cloaked Malware

Are these av companies? If so then inform them throught the support forums if you can't contact them
