Windows 10: Trojan horse virus

Ive been having this virus for months, I accidently downloaded a file in some website and it said that all my files would be hacked and I thought it was fake at first until my windows defender kept showing me that this trojan horse virus is making my computer space full. I tried to do something about it but it keeps showing up, what do i do? No matter what i click or do it keeps popping up.

Trojan horse

Thanks for information, I am running windows defender offline to see if that can remove Trojan horse

 

Trojan virus: Win32/Winexert!rfn

Click Remove all on that screen.

And by the way, note that there is no such thing as a "Trojan Virus." It's either a Trojan (full name: Trojan Horse) *or* a virus. They are two different types of malware. What you have is Trojan, not a Virus.

 

Trojan Horse

Is csrss.exe a trojan horse? It seems to me. it's part of system 32. It was installed on my computer in August 2013 by Microsoft. Need to know as soon as possible. I've been harassed by outside vendor to buy a very expensive firewall.
