Application extension company's for bitdefender & bitdefender VPN files

 Hello all,

I am having issues with my anti-virus software and was reviewing the program files, and noticed that all these extensions were from companies other than Bitdefender. I was wondering if this is normal? If not, I'll follow up in the anti-virus/malware section, but if this is normal, I'll continue here.

First comment will contain info on the companies I'm referencing.

Thanks a ton
