Virus that infects processes with high CPU usage and creates random process and .exe files with LAG

Like what I said above this virus infects processes with high CPU usage even if they are not meant to be.

It also creates multiple random letter processes with .exe files like rtqwb.exe or winltfr.exe which causes lag, and if I delete or end the task it just comes up with another file/process.

Please help me.

Thanks.
