This is not an antivirus program. This is not an antispyware program.

This is an application that helps prevent web-based exploits from gaining access to your system through your browser, from F-Secure, a world leader in internet security and malicious software detection.

About F-Secure Exploit Shield
F-Secure Exploit Shield is an application that protects users from web-based malicious exploits and stops malware at the first point of infection. All malicious, exploit-hosting URLs it detects are automatically reported back to F-Secure's Real-time Protection Network, which helps our Security Labs discover new exploits on the Internet and react to protect all our existing customers.

Supported platforms

  • Windows XP SP0, SP1, SP2 and SP3

Supported browsers

  • All versions of Microsoft Internet Explorer, Mozilla Firefox and FrontMotion Firefox

F-Secure Exploit Shield features

  • Zero Day Protection: Protects unpatched machines even before patches are available from the software vendor.
  • Patch-equivalent Protection: One 'shield' update per vulnerability stops all exploits targeting it.
  • Proactive Measures: Heuristic detection techniques block exploits even for unknown vulnerabilities.
  • Protects against both malicious websites and good websites that have been hacked.
  • Automatically sends detected malicious URLs from users to F-Secure.

Given the latest round of exploits for Internet Explorer, this program may add an additional layer of defense.
