World of Warcraft FPS is lagging

My FPS in WoW is severly lacking even when I have all the video settings turned all the way down. I have found some maleware and have hopefully removed all of it. Here is what I am running; Celeron D 3.2 GHz, 2GB RAM, and GeForce 7300GT running on XP. Is there anything that I can do to speed up the FPS in game. I love playing this game but getting less than 10FPS while raiding is just not cutting it. Also it sounds like the computer is running all the time so there might still be some maleware in there somewhere. :cry

 

that or your video card, no offense but i believe your vid card could use a good upgrading! might give you a good performance boost. and your CPU is a lil outdated as well but alone should be able to run the game, i think ur vid card would be your main problem.
