The one seems to indicate something plugged into the USBHUB.
The other points to safedrv.sys from World of Warcraft Garena Update (See
HERE) & SYMEVENT.SYS from Norton
So I suggest you fix your WOW, make sure Norton is up-to-date, update the drivers for all usb devices you have, and since you are gaming it's a good idea to make sure you have the latest video driver for your computer.
