Purchased Zone Alarm Extreme Security last June. Computer has Windows XP Home edition and Internet Explorer 8. My hobby is genealogical research.

When I have several Internet windows open, which is my ususal practice when researching, I sometimes get a message that there is not enough virtual memory. Don't recall ever getting that message before installing Extreme Security.

Have also received messages from Zone Alarm regarding "instability".

Would appreciate your input.

Thanks
