One of the latest versions of Kasperky's security software falsely identifies vstconnect.dll as 'Malicious Object' (Trojan.MSIL.CoinStealer.tf) and deletes or quarantines the file.
The report by Kaspersky is a false positive result. vstconnect.dll is not a trojan. vstconnect.dll is a Cubase component and required for internet connections via VST Connect.
Kaspersky already fixed the wrong detection. Please update your Kaspersky security software to the latest version. In case Kaspersky deleted vstconnect.dll and you want to use VST Connect features, please reinstall Cubase.
