Offline Anti-Virus Recommendations

Greetings All,

I have one workstation that is not allowed to connect to any type of network, including the Internet for security reasons.

I need to install one or more anti-virus, malware removal, etc. onto this machine but am having difficulty finding any decent products that can be downloaded onto another computer and then installed and updated on the machine that needs it.

I would welcome any and all recommendations!

Thanks in advance for your assistance.
