Spam is flooding the Internet with many copies of the same message, in an attempt to force the message on people who would not otherwise choose to receive it. Most spam is commercial advertising, often for dubious products, get-rich-quick schemes, or quasi-legal services. Spam costs the sender very little to send - most of the costs are paid for by the recipient or the carriers rather than by the sender.
OHC can offer an Anti Virus and Antispam solution that is a hosted, meaning that you do not need to buy expensive servers or spend time installing the software. Everything is done for you - you simply route your email traffic through our application server.
Another advantage of using a hosted solution is that potentially dangerous virus and spam mails are routed to external servers for quarantine, and thus never enter your system.
At the same time, all updates are performed automatically, meaning no more tedious work downloading the latest virus definitions etc.
