You probably have some kind of adware installed, assuming that your Mac is not actually running OS 9 or earlier (systems that date back to the 90s). I'm assuming that the forum choice was an error, as I doubt such an old system would even be capable of properly displaying modern websites. What version of Mac OS are you actually running? (Go to the Apple menu and choose About This Mac.)
Assuming you're actually running some version of Mac OS X, see my Adware Removal Guide for help finding and removing the adware.
