please review the attached hijackThis log. I ran all four tools according to your instuctions. Initially, there were two icons in the system tray with pop ups that stated "critical system errors". Also, everytime i would open internet explorer, pop ups would constantly appear. After running the four removal tools, it appears that after I restarted the computer that the system tray is back to normal (no more critical system errors)...but, I still receive pop-ups when I access my browser.
