recently pages opened in Firefox have highlighted spurious links which take me to various unwanted adds, like penny bid sites. Have spoken to website owners about the problem and they suggested i may have a trojan - using mac oxs 10.8.2. Used anti virus clam and found no trojan and spurious links persists even after emptying cache and deleting cookies. Any suggestions? tah
