There are a lot of viruses on the web. I don’t want them on my computer. So I search with Scandoo. Scandoo tells you what sites are safe and what aren’t. If a site is safe there is a tick beside it. If the site has bad things in it there’s an x beside it. If Scandoo doesn’t know if the site is good or bad then there’s a ? beside it. It’s safer to not go into the sites with ?s. If you happen to click on a pop-up window Scandoo won’t stop you.
