I keep getting this prompt: TR/Gendal.kdv.304884 from Avira antivirus
The Zapplink or Go z in previous version also have similar prompt, should I be concern?
Sounds like a false positive to me. ZBrush is not a Trojan and never requests internet access except for activation and deactivation of it’s license. You would probably get a better answer from Avira support however.
