A-random,
Gozilla has embedded code that reports your browsing activity back to some a r s e h o l e s who then target you with advertising that they think you will be susceptible to. What's worse is they don't tell you about it and after you uninstall Gozilla the adbot software stays on your system and continues to do its surreptitious reporting thing.
You can find out more from
www.grc.com . Follow the links to Optout and internet security and privacy.
I don't know how everyone else feels, but I do not like to support or use a company or product that behaves in such an underhand way.
The GRC site recommends a personal firewall called Zone Alarm which I use and highly recommend. I only use a dial-up connection, but its amazing how many people try to snoop your system while on line, even for short periods like an hour or so. Zone Alarm stops them, reports their attempts to you and also prevents the ad bots in software like Gozilla from sending their info about you from your computer.
Cheers,
A paranoid AA
