[lorcav123]

What is the best program to dicover these viruses? I recenty had 4, discovered with Malwarebytes, I think that my PC is clean (scaned againg with Malwarebytes and Avast free, all clean) but when surfing I got small GPU usage spikes. Is that normal?

That looks normal. You should see small GPU usage spikes. Cryptocurrency miner malware usually results in a more constant GPU usage.
