Cisco AnyConnect denies connection after failing to recognize antivirus
I cannot say I fully grok how anti-virus comes into play with your VPN software, but AnyConnect is a notoriously flaky VPN client. You are better off using the native VPN connection built into the OS. You will need to create a new Cisco VPN connection and most importantly, You will need the gateway IP, Group ID, and shared secret for your connection from your IT folk. You may find them quite reasonable about giving your that especially if you are are being locked out and can solve your problem with some self-sufficiency.
