Yesterday, I was Diviantart.com and clicked on a picture I wanted to see, and it tried to redirect me to a fake Antivirus website, my Avast! Quickly blocked a trojan attack and I immediately shut down the computer to prevent infection. Before I did that, my CPU was never at 100% for no reason, I don't quite understand why it is doing it.

Here is a HijackThis log:

Whenever I open taskmanager to see why my games are lagging so much (they never did before) it doesn't really show anything taking up much CPU
That is why I am suspecting a Trojan or two got inside
But I have had no popups of anything suspicious since last night
As soon as I saw the dialog it said ("Your computer is under danger. Huge trojan attack") or something like that then my avast pops in the corner and says "Blocked Trojan attack." and the website didnt load because I didn't click Okay but the website was a .Info and I just used the power button to shut down the computer and didn't click anything
so the fake didn't install, but I think a trojan might have gotten through because of the 100% CPU all the time
