Enable Site Check

Checks security-related information about each site you visit. See Web Site Safety Check and Rating for more information.

Enable anti-phishing (signature)

At each site you visit, ZoneAlarm browser security checks an online anti-phishing signature database to see if the site has been reported as a phishing site.

Enable anti-phishing (heuristics)

ZoneAlarm browser security analyzes each site you visit for phishing characteristics, so it can catch even new sites that haven’t been reported yet.

Block spyware websites

Protects you from sites that distribute spyware to your computer, either silently or by embedding spyware in downloads that appear to be trustworthy.

Check file downloads for spyware

Executable downloads (programs) are checked for spyware in three different ways.

Block programs that secretly record your keystrokes*

For maximum protection of data you enter online, choose Always. However, this setting may block the occasional legitimate program that uses keylogging, such as language translation programs, volume control, online conferencing, or child monitoring programs. If you have conflicts using any of those programs, use Only in allegedly secure sessions (https). This way you will still be protected when entering important data on secure sites.

Virtualization

Keep virtualization enabled to maximize your protection with the safe, virtual "net" that catches drive-by downloads.

For a description of virtualization, see Virtualization: A Defense Shield*.

Clear virtual data

Deletes all unsolicited downloads caught in the protective virtual file system. Executable ones are deleted automatically, but other files are left behind. Clear virtual data to conserve disk space. Also deletes browser download history list and browser cache.
