Although the promotion is only running today users who download the virtualization software have seven days to install it and are still eligible to use it freely. The registration key will be send to the email address entered during registration and is good for one year of free updates.

Zonealarm Forcefield is compatible to Microsoft Internet Explorer 6 and Internet Explorer 7 as well as Mozilla Firefox 2 and Firefox 3. No Opera support in sight unfortunately though.

ZoneAlarm Forcefield adds a toolbar to the browser which thankfully can be shortened so that the icons only appear in the statubs bar and are thus less obtrusive.

Features:

• Browser Threat Immunity
• Keylogger & Screengrabber Jamming
• Anti-Phishing
• Spy Site Blocking
• On-The-Fly Encryption
• Website Safety Check

Unlike the other two virtualization software programs ZoneAlarm Forcefield virtualises only the browser and not other applications that connect to the Internet.
