Leading security firm, Symantec, has recently done an interesting study. On a daily basis from February to May, they took a look at the top 300 search topics on a leading search engine (probably Google since that’s all we use anyway) and analyzed the top 30,000 results. Their findings were that 1 in every 3 search results were malicious, SEO poisoned pages. More alarming, is that they found on some days, “more than 250 of the top 300 daily search terms returned more than 10 percent malicious links within the first 100 results.” Yikes! Make sure you run good, up to date antivirus since that will help with these kinds of threats. However, the best piece of advice I can give you is to think before you click on a link. There may be clues in the search engine results or the link itself indicating that the page is malicious. Also, use Firefox or Chrome. Both of those browsers have built in protection against a lot of these malicious pages.
