Anti Spam and Firefox/IE7

After installing Anti Spam as soon as I open a browser, either Firefox or IE7, I get the error message that there is a problem with Firefox/IE and it needs to shut down.

I had to uninstall Anti Spam or I would not be able to open a browser.

I also would like to try the antispam program, but I’m concerned about using Firefox and Earthlink’s totalaccess mailbox programs. I’ve already had problems with Earthlink and CAV. The sys. requirements do not say anything about using Firefox browser. Any progress with these two programs?
PS: I just love the firewall program!!
