Awesomehp removal?

[SUVCamel]

Hello guys,

I accidentally downloaded Awesomehp and it appeared in my browser. I am not sure how exactly I did it..maybe while downloading another program, but anyways I found a removal guide and I think it's gone but the article i read said I need an antivirus program to remove it completely. Is that true? Is it still in my PC even If I don't see it anymore? So should I use one, or is everything fine already? Thank you!
