Have more control over what programs can do
By default, Windows Vista runs your programs in a more secure mode. If an application attempts to perform a potentially dangerous operation that requires administrator privileges, Windows Vista asks you for your consent before allowing that program to run. This helps reduce the impact of viruses, spyware, and other threats.
Browse confidently with Internet Explorer 7 Protected Mode
This Windows Vista-only feature limits Internet Explorer 7 to just enough permissions for you to browse the Web, but not enough to modify your files or settings—which helps keep your computer safe from Web-based attacks.
Get more safeguards from Windows Security Center
The Windows Security Center notifies you and helps you take action to correct a problem when your security software is not up-to-date or your security settings are potentially unsafe.
In Windows Vista, the Windows Security Center is improved to include information about your antispyware software, Internet Explorer settings, and User Account Control settings.
