NB: be careful NOT to run sudo launchctl and NOT to run launchctl from a root terminal, because launchctl is user-dependent. For example, trying to run sudo launchctl unload -w /Library/LaunchAgents/com.cisco.anyconnect.gui.plist results in an error "Could not find specified service", whereas without the sudo it works.
However, I do not see those three files you seem to mention. I find on my system only 'com.cisco.anyconnect.ciscod.plist' and 'com.cisco.anyconnect.vpnagentd.plist' in the directory '/Library/LaunchAgents'. Perhaps more importantly, while setting in these two files the parameter 'RunAtLoad' to 'false' indeed prevents the annoying reinstallation of the application 'Cisco AnyConnect Secure Mobility Client.app' as a login item after a restart, it also makes the vpn in general disfunctional.
We are having this same issue at the University. After we updated the cisco anyconnect client to the latest version, everyone who has mcafee installed gets the SSO error message from the anyconnect client. We would instruct our users to disable their personal firewall for 15mins then connect to the VPN and it works fine. I've tried everything mentioned on this page without any luck. I've opened a TAC case with cisco and this seems to be an issue with Mcafee. Our helpdesk is getting swamped with calls from students, faculty, and staff. Can someone please look into this issue.
