Bing's top search result for a database tool that I was trying to download for work was not the tool's official website but was a fake website containing malware designed to look like the real one. Due to Bing putting it top, I trusted it and downloaded what I thought was the tool, only to end up with Malware on my PC. It's literally shocking that you'd take money to boost the SEO of a site without actually checking to see if it was going to give users malware.
