Hi All, this is the first time I've posted to a forum requesting help. So thank you in advance, and apologies if I leave something out. I'm running OS 10.5.8 and using Firefox 3.5.7. When I Google something and click a result, 75% of the time I am redirected somewhere that was not the destination of the link. Other times I'll click a link and a giant white browser window will open behind current window taking up my whole screen. Another frequent occurrence is being directed to the site "theclickcheck.com". I have a registered version of MacScan and it comes up with nothing and my software is up to date. Where do I go from here?
