Google links redirected to random pages

When I search something in Google and click on the links that seem to contain what i'm looking for, I don't get directed to the page I'm looking for. Instead, I get directed to a random page (search engines and pages which contain just a lot of other links). If I copy the link and paste it in the address bar I do get the right page. What is the problem and what can I do to fix it?

you probably have some type of spyware down load the free personal edition of ad-aware from http://www.download.com/Ad-Aware-SE-...bj=dl&tag=top5
install it, check for updates, run a full system scan, select all critical objects for removal and see if this has fixed the problem. good luck.
