Are there miners and so on on Linux?

Question

linux

one day (today) I turned on the computer, and realized that EVERYTHING LAG, especially the browser and games.

But before that I did not download anything, but still in doubt.

Are there miners in linux OS? And how can I see what processes are loading the video card?

Answer 1

It would be better to check less fantastic versions: what's with the video driver and whether the percentage is throttling from overheating.
Disk problems, for example, can cause not only brakes, but also friezes.
But, of course, nothing prevents you from looking at top and logs.
Or boot from the installation flash drive and compare the browser.

Answer 2

Option 1.
Everything starts to shamelessly lag when you get into swap. This happens when the free RAM is about to run out, or has already ended. In fact, instead of the RAM, the hard drive starts to be used.
You can view it in the terminal using htop.
You can clear swap like this:
1. Close RAM-intensive processes
2. Disable and enable swap:
sudo swapoff -a && sudo swapon -a
Option 2.
Something ate the CPU, maybe Ubuntu telemetry (whoopsie process), maybe something else.
You can view it in the terminal using htop.
Option 3.
Something ate the hard drive.
You can view it in the terminal, through iotop.
Option 4.
Perhaps something did eat the video (this is less likely, but still). See the answer here: https://askubuntu.com/questions/387594/how-to-meas...
Although, there are times when the same chrome is better off without GPU acceleration.
First, you should determine what is eating resources and, based on this, seek treatment. The silver bullet in the style of "run this and you will have a pony, a rainbow and menstrual cramps", unfortunately not.

Answer 3

There are no viruses in Linux!
Well actually I lied.
There are ainers and worms and other fauna.
The first reason is that there are no lamers (now there are none), the second one is non-proliferation, again (now there is).
"People" are interested (hi ​​popularity)
What to do?
Alternatively, it is an antivirus.
Another option Is there an analogue of sfc under Linux?

Answer 4

Are there miners in linux OS?

Yes. And ransomware, Trojans, and other malware.

And how can I see what processes are loading the video card?

Processes on the video card... An interesting thing... How do you imagine dispatching what is happening on the video card?
