Sometimes, an advert will be disguised as a legitimate part of a website, such as a button to download a piece of software.

When you click the advert, you’ll be taken to a scam website.

Some scam adverts can appear in popular search engines.

When you search certain phrases on websites like Google, you may find that the sponsored search results are scams.

Also, if you’ve been browsing an innocent website before being automatically taken to a suspicious one, there’s a good chance an advert was to blame.
