Unfortunately that didn't work. I'll see if I can get our systems admin to add an exclusion in Bitdefender to allow that file through.
Apologies for late reply, but this issue appears to be because Bitdefender is identifying Volo.Abp.Suite.dll as containing Malware:
On-Access scanning has detected a threat. The file has been deleted.C:\Users\StephenHynds.dotnet\tools.store.stage\ymxm0yfs.h5s\volo.abp.suite\9.1.1\tools\net9.0\any\Volo.Abp.Suite.dll is malware of type IL:Trojan.MSILZilla.190641
Are you aware of any issues in the current version of ABP Suite?
Thanks! That helped me narrow down what I was trying to do and I've got it working.
