Started off with just a few computers but now reaching over 10.
I could not find any info on how to upgrade on the website, does cancelling Bitdefender Ultimate Security home and purchasing GravityZone Small Business Security involves having to uninstall and reinstall all devices? not even sure if GravityZone Small Business Security is the right product, no need for VPN, only need antivirus/malware and randsomeware protection.
