Interesting new browser plugin for Firefox or Internet Explorer with realtime link and code scanning. May be a strong competitor for McAfee SiteAdvisor.

SecureBrowsing plugin by Finjan:

Gives you the highest rate of malicious code detection:

• Scans the current form of a page as it available on the Web now, in real-time.
• Detects malicious content based on code analysis, rather than using signatures like anti-virus products.
• Provides the most accurate page safety rating based on the actual page content, rather than database lookup of web address like URL filtering products.

Ensuring your privacy:

• Doesn’t track each and every URL you visit.
• Doesn’t require your identification details.
• Doesn’t install additional programs or change settings of your desktop.
