Machine infected with fatalofi.dll

my computer seems to be infected with some kind of malware, i run malwarebytes and norton and they seem to consistantly find some kind of virus and/or trojan present, but even after those are remediated i keep getting pop up messages saying something to the effect of C:\WINDOWS\system32\fatalofi.dll, are there any suggestions, first timer not incredibly computer saavy, thanks
