I’ve been hacked

Can someone help me to identify the likely hacking activity was being conducted on one of my WinXp Voicemail systems (we had a weak password)? The following programs had been installed and a few accounts were created. I’ve disabled the accounts that were created and de-installed the programs listed below.
