I have been infected from an Italian site by a bad site dialer which I cannot delete, because it is in use by another file. Norton Anti-Virus does not identify it as a threat, and Norton Internet Security 2003 has not caught it dialing out. Can I identify the other file using it? If so, can both files be deleted simultaneously, if the other file is not a system file? Can the connection to the other file be severed? The OS is XP. Suggestions would be appreciated.
