Computer slows down my internet?

For some weeks I have had the problem that my computer slows down my internet. That means when I turn on my computer the whole network is extremely slow eg. With the mobile phone and laptop. However, if the computer is turned off, all devices will run normally. On the computer I have already tried the following things: Antivirus Scan, Network Driver updated, Windows reset, Windows Updates checked, in the Task Manager all programs run only with 0.1 Mbit / s

What else could be the reason?

Boats the computer times in safe mode with network drivers. Does the problem persist then?

Ma

Yes, it persists

How is the PC connected to the router / internet?

Ma

Over a LAN cable

Now if you pull the LAN cable on the fly, what effect does that have on your network?

Ma

Then the internet is back to normal.

Ogott this is slow 2 megabytes per second and also a part of it is canceled because of the long copper line I think it is because of your Internet
