I came over to see what was wrong on my sister's computer. Whenever she would open up Firefox, IE would also open up and the computer would grind to a halt. Sometimes ctr+alt+del would help reboot but usually it would not and you had to hard reset. This would only happen on her profile. I did all the preliminary removal steps and the problem is gone. But AVG Anti-Spyware found a trojan.small and I just wanted to know what to do next. AVG virus scanner had also found a trojan but even after deleting file, or healing it, it would always come back. requested files are attached. combofix and panda found nothing.
