A malicious Home Depot ad campaign is redirecting Google search visitors to tech support scams. The ad is the top spot in the research result, making it more likely to be clicked. Once a tech support scam is shown by clicking on the ad, subsequent clicks bring visitors to the legitimate site. Users are advised to pay more attention to Google search results to not click on ads instead of the legitimate search page result for the company. The scam will repeatedly open the Print dialog box, which prevents the visitor from easily closing the page.
