Hello, my computer is being really slow for the last 2 days. I know because my tower has a blue light indicates when it's really doing something. Example: right now, it is shining for a long time, and when it stops shining, a command goes through. Like I click on my firefox launcher, the light shines for a while, and after a few minutes firefox finally comes out.
I am afraid that I'm infected with some annoying virus or some Malware of some sort, and I want this to end. so please help me, thank you
