Yes, I understand you, but it wasn't me who entered it. It entered through some program because I bought the computer with activated Windows. It expired days ago, and I don't know why. But are you sure it's the only virus? Because I think and am sure there are many. Have you seen KMS alone? The computer's fan keeps running even though I'm doing normal tasks or not doing anything. And if I install a new Windows, as in the previous links, will there be no virus left, even if it's in the BIOS? Please answer me carefully because I'm scared and don't understand much in this field, and I involve you from the depths of my heart.
