Exclude Virtual Machine Directories In Your Antivirus

[Solarquest]

I just read on http://www.howtogeek.com/124796/the-htg-guide-to-speeding-up-your-virtual-machines/ that "....Your antivirus may be scanning your virtual machine files whenever they’re accessed, reducing performance. The antivirus can’t see inside the virtual machine to detect viruses running on your guest operating systems, so this scanning isn’t helpful."...

is this true? In some test I saw the host AV blocking malware/bad web pages run in the guest......just doubting......

Is the true.

Tested with a malicious link, my antivirus ( Norton IS 2014 ) block the link (in my real PC )

He is talking about files not the eb filter

It's true.
No security software can scan files in a virtual machine, only if it's shared with the host.
But, it's will not slow the virtual machine, that is false.

The blocked websites are by-network.

Had this happen multiple times, but if I'm right there should a setting within the network settings of the VM, where your host won't scan the VM. Before I knew about this feature, I was just disabling my web protection for testing.
