Introduction
There are 3 tools in Windows:
-
Performance Monitor. This is the oldest one, and is superceded by the next two.
-
Task Manager
-
Resource Monitor
They use different names. It is also possible that they use different formula.
One major difference between Guest OS and VM is that Windows/Linux runs a lot of threads and processes. The problem is there is minimal observability on individual thread or process. For example, there is no CPU queue metric, memory page fault, network dropped packet, and disk latency at process level.
The following shows Windows Sysinternal1, a great tool for Windows troubleshooting. As you can see, they are just utilization metrics. There is no contention metric.

Your anti-walware may classify it as a threat even though it is obviously not a malware. Malware uses psexec, a component of sysinternal, to execute commands on remote machines. Some of the executables also behave in such a way that anti-malware software classifies them as malicious. ↩
