Symantec is detecting two files - Trojan Horse

How is the machine running now?

It is running fine but still getting the two messages from Symantec Endpoint Protection:

Hello.

TFC(Temp File Cleaner):

• Please download TFC to your desktop,
  
• Save any unsaved work. TFC will close all open application windows.
  
• Double-click TFC.exe to run the program.
  
• If prompted, click "Yes" to reboot.
  

Note: Save your work. TFC will automatically close any open programs, let it run uninterrupted. It shouldn't take longer take a couple of minutes, and may only take a few seconds. Only if needed will you be prompted to reboot.

Does Symantec still complain now?

What were you doing when that alert appeared?

I was running Firefox, Outlook, and Digsby.

Something from them may have triggered the alert.

I would recommend trying Google Chrome for now rather than Firefox and see what happens, it's just a matter of trying to pin point this.
