XP Guardian and Its Family come from One Root

Neither XP nor any other Windows version can be protected by XP Guardian. It is a counterfeit.

XP Guardian is based on a multiuse executables. Multiuse means they are used in different programs, though the main difference between those different programs is their names. Such a diversity is reasonable as it creates complications for malware experts and, consequentially, removal tools, as well as it prevents coverage of all the names by removal guides. So far, up to dozen of XP Guardian clones are detected. No doubt, there will be more. A current list is as follows:
1. Vista group: Vista Antispyware 2010, Vista Internet Security 2010, Antivirus Vista 2010, Vista Guardian, Vista Antivirus Pro 2010
2. XP group: Antivirus XP 2010, XP Antivirus Pro, XP AntiSpyware 2010
XP Internet Security, XP Internet Security 2010
3. Win7 group: Win 7 Internet Security 2010, Win7 Guardian, Win 7 Antivirus Pro, Win 7 Antispyware 2010
You need to remove XP Guardian to serf the web freely.
