Re: cisco anyconnect vpn
As it said, it's a client for the Cisco AnyConnect VPN. If you need to connect to an AnyConnect VPN, it'll be quite useful. If you *don't* try to connect to an AnyConnect VPN, it won't be doing anything at all other than taking up a tiny bit of disk space. Removing it certainly won't make your system any more responsive; if you've observed that then it's just a coincidence.
