We are attempting to get our 2019.4 HF 5 server running NCM 8.0 upgraded to HF 6 and Symantec found the same Sunburst virus/malware in the installation package. We had already implemented the HF 5 security fix so we could get our server out of quarantine and this put us right back in there. What other options do we have? Do we have to jump immediately to 2020.2.1 HF 2 to get a clean update?
