(Continuation from yesterday)

Today, I finally found the cause of the "inactive system".

It was security software (Macfee) that was pre-installed on the PC.

Uninstalling this software to an unrecoverable level, resolved this three problems at once, and the system started.

The reason the system did not work even if I changed the setting of Windows OS, that this software was blocking the system.

Even so, although it is acceptable to block ping and http packets, how this malicious software interferes with the process on the personal computer.

Though it was only a moment, I thought of "an arson" to this company.

However, security software is designed to protect PCs from "malicious" software developers.

The majority of PCs are "users", and on the other hand, "developers" do not reach 0.2% (300,000 / 130 million) of them.

So, the behavior of this software is "not wrong", rather it can be said that "work well".

However, if the software crush everything, it would be safe.

- It continues to monitor not only external attacks, but also spyware that may have entered the internal process.

This is like a former socialist state and a present dictatorship, where a petition was encouraged.

- In addition, it ignores the laws of the world (settings of Windows 10) recognized by the legislative body (system administrator) of that country, and continues monitoring, and eliminates if necessary.

This is like a secret police lurking in the country illegally.
