Some trojan horse or virus generates files upon start-up. These exe. files end up in my registry and over time, consume enough memory that the system becomes unstable and fails. Moreover, my web browser has been hijacked and the home page is set to res://pfess.dll/index.html#17664 and I can't change it. When I delete the pfess.dll file it reappears.

I have run the Hijack This program and the log file is below.
