[mpack]

Thanks for the log. This seems straightforward: you have McAfee installed, with its tendrils everywhere.

Thanksfor confirming it as I suspected Macafee is a nightmare, not my choice I'm afraid have to live with it

Woudl simply exclusind VBOX exe runtime from AV scan be enough or is there a definete list of other files / paths that shoudl be exculed as didnt see this in fAQ

[scottgus1]

Exclude everything in the Virtualbox installation folder, the global settings folder (usually C:\Users\{you}\.Virtualbox), and every folder that has a guest .vbox file in it, as well as any guest virtual disk file that is not in the folder with the guest .vbox file.

You will need to try these exceptions and see if they work, we don't know if it will be successful.
