My Communicator.exe is taking up 96% CPU. I have to run this program for work to chat with my coworkers... what could be causing it to use such a high CPU percent?

From here

Communicator.exe is located in a subfolder of "C:\Program Files". The file size on Windows XP is 4,167,376 bytes. There is an icon for this program on the taskbar next to the clock. The program has a visible window. The application can be uninstalled in the Control Panel. It is digitally signed. Program starts when Windows starts

see Registry key: HKEY_USERS.DEFAULT\Software\Microsoft\Windows\CurrentVersion\Run, HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Run).

It is not a Windows core file. The application listens for or sends data on open ports to LAN or Internet. Communicator.exe is able to record inputs. Therefore the technical security rating is 6% dangerous, however also read the users reviews.

Important: Some malware camouflage themselves as Communicator.exe, particularly if they are located in c:\windows or c:\windows\system32 folder

Check it those one is good one or bad

I find that it's usually not Communicator.exe which is primarily responsible, it's some collusion it has with Outlook. I experienced the same problem you had, but due to continuing troubles with Outlook, I finally abandoned it and switched primarily over to OWA Outlook Web Access. Amazingly around the same time, Communicator also got better.

First try a repair. If that doesn't work try to do a re-install. Hopefully that will fix the problem.
