I have the same thing happening, but in addition, my browser (ie9 or firefox) is getting redirected sometimes. Don't know if it's the same problem or if they just both showed up at about the same time. Norton 360 keeps telling me the trojan is solved, but it keeps coming back. 1st showed up late last night, reoccurred about every 4 min, still reoccurring but less often-- about every 10 min.
Info from n360 below:( last time I recorded it.)
