Well, the fact that OneCare is going to be retired is true. See this post:
The message you pasted is wrong on one count and the first sentence isn't strong enough regarding the reply to the subject line. AntiVirus 2009 is rogue spyware and very hard to eradicate once you have been coaxed into installing it via the very official looking popups. The incorrect part of the statement is what will be and will not be in Morro, the code name for the new product. We don't know much yet, but we know from the announcements that Morro will be a free antivirus/anti-spyware product using the same technology used in OneCare, Defender, and Forefront, but expanded on. What will not be included in Morro, which are part of OneCare, are Tune-up, Backup, Multi-PC Management, Printer Sharing, WiFi Security, System Setting monitoring, and probably the Firewall.
