In the past thirty days I've installed two updates to Parallels 9 on my iMac Running (OS X) plus updates to windows 8.1. With each update and at other times also, my Avast Antivirus states that it has detected and quarantined Dead-B Virus. The specific file quarantined is users/shared/parallels/windows 8.pvm. I have had 6 specific detections and quarantines since March 26. Is this and accurate detection? Is this file required for Parallels to run correctly? I do not see any degradation in my parallels or windows performance.
That file, a bundle, is actually your Virtual Machine or one of your VMs if you have more than one. No, it's not safe to delete, you should run an antivirus on Windows to check if it has a virus you can also add the bundle to the exclusion list.
Thanks for the input. Following the intent of your advise, I ran a 100% virus check with Windows Defender on the Windows Virtual Machine. After that came up clean, I went to my Avast Antivirus software and added the windows 8.pvm file to my exclusion list for virus searches. It's been about 4 days and I have not seen the virus warning since completing these actions.
