1. The mouse itself wanted to install its software. I don’t know where it came from from the Internet or put it into a computer via bluetooth. The antivirus missed, and the HP protection system blocked it. See screenshots. 2. The mouse disconnects from the bluetooth if you do not touch it for about 10 minutes. It will connect from 10 seconds to several minutes . WILDLY STRAINS. Why switch off? . 3. The Razer wheel spins in jerks, not smoothly. Previously, they used the old Logitek, the Logitek wheel turned smoothly, but over time it deteriorated over many years. Under the "cover" of the mouse, I found an adapter for the radio channel. Connected via radio, the mouse stopped disconnecting from the computer. Everything works well. As soon as I inserted the adapter for the radio channel into the computer - so immediately, apparently, the installation program crawled into the computer from it. The antivirus missed again, and the HP system blocked three attempts to shove this muck into the computer.
