For the past few months whenever I use Google and I click on some of the results, it results in a redirect to a completely unrelated page. The pages seem harmless and don't bring up any popups, but it's been getting extremely frequent (over half the links I click).
Also (not related to above), Norton has been picking up a "Tracur Trojan Activity" whenever I'm on the internet. It only pops up on Norton, but I thought that I could try to get rid of it before it could possibly get worse. Here's a screenshot of how it appears on Norton:

Any help is greatly appreciated. :)
