Communications Server 2007 R2

Microsoft Office Communications Server 2007 and Microsoft Office Communications Server 2007 R2 will reach end of support on January 9, 2018. To stay supported, you will need to upgrade. For more information, see Resources to help you upgrade your Office 2007 servers and clients.

A virus is a unit of code whose purpose is to reproduce additional, similar code units. To work, a virus needs a host, such as a file, e-mail, or program. Like a virus, a worm is a unit of code that is coded to reproduce additional, similar code units, but that unlike a virus does not need a host. Viruses and worms primarily show up during file transfers between clients or when URLs are sent from other users. If a virus is on your computer, it can, for example, use your identity and send instant messages on your behalf.
