you will have to run a spyware removal program like Ad-Aware and several others like it to see if they can remove the program. http://www.lavasoftusa.com/software/adaware/. you sometimes can use CTRL-ALT-DEL to bring up Task Manager and find the program to stop it.

Hi!
A rogue e-mail attachment has created a folder and placed a dialer and another small executable file in it on my Windows XP system. I have deleted the dialer, but cannot delete the other file because Windows says the file is in use, even though I have not launched Explorer. This file takes me to a specific web-site when I do launch Explorer. Starting the computer in safe mode will still not allow me to delete the file. Any ideas? Thanks!
