Problem with FPS in convoy. (Euro Truck Simulator 2)

I recently ran into a rather strange problem. In offline mode, the game gives a stable 35-40 FPS on ultra settings, and about 30 in convoy. That was until yesterday. Entering the convoy, I found that the number of frames per second dropped to 5-10! And it doesn't go higher. Reinstalling the game didn't help. I could not find ABSOLUTELY NO information about this on the Internet. I suffered for several days until I decided to check the system for loading. Imagine my surprise when I found that the GPU was 98% loaded with no programs running! The answer is obvious the computer is infected by the miner. Was I surprised when I discovered it? The answer is obvious. After cleaning the FPS just took off into space) I'm happy as an elephant. You never know, suddenly someone else will google and it will really help him.
PS You can google how to deal with miners, but if suddenly a virus does not allow you to enter a site with an antivirus, then the algorithm is as follows: download the Dr.Web Cureit utility to any other device (or flash drive), I used a tablet. It weighs only 250 MB, copy it to your desktop, run it and after 10-15 minutes everything will be ready.
