As far as changes go.. nothing that I can recall specifically; I didn't receive the error until I attempted a Windows update 1-2 months ago.. so I have no idea really..
I can tell you with 100% certainty that I haven't installed any new hardware in just about a year; software wise.. nothing recent as of this error..
I did have a round with a Trojan virus (zlob.gen) a few months back that I am not convinced was ever fully eradicated from my system (I still get a pop-up warning about Trojan.zlob from NOD32 anti-virus when I do an online scan over at TrendMicro)
What is odd however, is that even when I was fighting to get this virus off my system, I was still able to update my Windows OS and Defender programs.. but now all of a sudden, I can't.
Thanks for any and all help you guys can provide.
