Somebody on your team needs a PDF reader, or the login page for the bank, or the download for the label printer software. They search for it. The first thing on the page is the answer, so they click it. That first thing is often a paid Google Ads slot, and scam Google Ads are one of the easiest ways for a criminal to get inside a small business right now.

I want to explain how that works, because once you see it, you cannot unsee it, and your team stops clicking. That is the whole fix. It is a habit, not a product.

How scam Google Ads work

Start with what you already know. When you search Google, the top of the page belongs to ads. They are marked with a small “Sponsored” label, but they look almost identical to the real results underneath, and they sit exactly where your eye lands first. Those slots are Google Ads, and anyone can buy them.

That includes criminals.

Here is the sequence. A scammer buys a Google Ads placement for a search people trust, like the name of a bank, “Microsoft 365 login,” or a common free program such as a PDF reader or a video player. The ad shows the real company’s name and logo. The web address in the ad looks right, or close enough that nobody looks twice.

Someone clicks. They land on a page built to look exactly like the real one. If it is a login page, the username and password they type go straight to the scammer. If it is a download page, the file they install is the real program with something extra packed inside, or nothing but the something extra.

The industry name for this is malvertising, meaning malicious advertising. You do not need the word. You need to know that a Google Ads result can sit right at the top of a perfectly normal search and still be a trap.

Why bad Google Ads get past Google

The natural question is why Google allows this. It does not, and it removes an enormous number of these ads. In its 2025 Ads Safety Report, Google said it blocked or removed more than 8.3 billion ads that broke its rules, suspended 24.9 million advertiser accounts, and took down 602 million ads tied to scams. It also noted that criminals now use AI to produce fake Google Ads faster.

So why do any get through? Because the scammers show Google one thing and show you another. When Google’s review system visits the landing page, it sees a clean, harmless site. When a real person in Nederland clicks that same ad from an office computer, the page quietly switches to the malicious version. The ad passes review and still does its damage.

Security researchers have caught these campaigns impersonating everyday programs like VLC, 7-Zip and CCleaner, and even Google’s own apps, with downloads that installed password stealing software. Those are searches your team runs on a normal Tuesday.

I should be straight about the limits here. Google is genuinely trying, and the numbers above are real work. But a system that reviews billions of Google Ads will let some through, and the ones that get through are aimed at exactly the searches ordinary people make.

Why a Google Ads scam catches smart people

An email scam has to convince you. A scam Google Ads result does not, because you went looking for it.

That is the part I want to teach. Every other warning you have heard about scams is about something arriving uninvited. A strange email, a text from a number you do not know, a pop up. Your guard is up for those. But when you typed “QuickBooks download” yourself and a QuickBooks download appeared at the top, there is nothing to be suspicious of. You asked, and Google answered.

The ad also sits above the real listing, uses the real name, and often uses a web address that differs from the real one by a single letter. On a phone, where the address bar is tiny, that difference is invisible.

What a Google Ads scam looks like in a Southeast Texas business

For a small business the risk shows up in two ordinary moments: downloading software and logging in.

The download version. A new hire at a body shop needs the estimating software, or someone needs a free tool to open a file. They search, click the top Google Ads result, install it. The program runs fine. What also ran is something that reads every password saved in the browser and sends them off. Nobody notices anything, because nothing looks broken.

The login version. Someone searches “Microsoft 365 login” or the name of the bank because the bookmark is on the other computer. They click it, type their username and password into a perfect copy of the real page, and get an error. They try again on the real page and it works. They think nothing of it. The scammer now has a working login.

The thing behind both of these is what the industry calls info stealing malware. Once it is on a machine it collects saved passwords, browser cookies and session tokens. That last one matters more than people realize. A session token can get an attacker into an account even when multi-factor sign in is switched on, because it steals the “already logged in” state rather than the password. We explained that mechanism in our post on how session hijacking works.

We actually wrote about search ads once before, back in December 2024 when this was on the rise. It is worse now, not better, and the AI angle is new.

Four habits that beat scam Google Ads

You do not need to buy anything. You need four habits, and the first one does most of the work.

Scroll past the sponsored results. That is it. The Google Ads sit at the top, marked “Sponsored” or “Ad.” The real website is usually the first thing underneath. Teach your team to skip the top of the page the way they skip the ads in a magazine. Once someone knows the top slot is for sale, they stop trusting it automatically.

Never download software from a Google Ads result. Type the maker’s address into the browser yourself, or use the normal result, then download from the official site. If you are not sure what the official site is, ask us. That is a thirty second question and we would much rather answer it than clean up afterward.

Bookmark the sites you log into. The bank, Microsoft 365, payroll, the parts supplier portal. A saved bookmark takes you to the real page every time and removes the search, and the Google Ads, entirely. This is the one I push hardest with clients, because it fixes the login version of the scam completely and it takes two minutes.

Tell your team this is a thing. Most people have no idea the top result can be a paid Google Ads slot that is fake. The moment they know, they stop clicking it. This is a five minute conversation at the start of a shift.

What we set up so a click does less damage

Habits are the main defense. There are a few things we set up behind them so that when someone does click a bad result, it costs less.

Automatic updates on every computer and browser, so a bad download has fewer holes to use. Removing local admin rights, so a download cannot install itself deep in the system without someone with the right credentials approving it. We covered why that one matters in our post on revoking admin rights. And the endpoint protection we run through our endpoint protection service, which is built to catch the kind of program that reads browser passwords, even when the download looked legitimate.

A reputable ad blocker helps too, because it hides sponsored results before anyone can click them. It is not a complete fix. Keep the habits.

What to do if someone already clicked one

It depends on how far it went.

If they only visited the page and typed nothing, close it. Nothing happened.

If they typed a password, change it right now, and turn on multi-factor sign in for that account if it was not already on. Then think about where else that password is used, because the answer is almost always somewhere.

If they downloaded and ran a file, disconnect that computer from the network and have it checked. Do not just run an antivirus scan and go back to work. Password stealing software is designed to finish its job and leave quietly, and the thing you care about is what it already sent, not whether it is still there.

Passwords saved in the browser on that machine should be treated as taken. Yes, all of them.

Frequently asked questions

Are the ads at the top of Google safe? Not always. Google reviews Google Ads and removes billions that break its rules, but scammers get some through by showing reviewers a clean page and everyone else the malicious one. A “Sponsored” label is not a safety label.

What is malvertising? Malvertising is short for malicious advertising. Scammers buy Google Ads and other online ads, often using trusted brand names, to send people to fake sites that steal logins or install malware.

How do I download software safely? Go to the maker’s official website by typing the address yourself, or use the normal, non-ad search result. Never download from a Google Ads result.

How do I know if a search result is an ad? Look for a small “Sponsored” or “Ad” label above or beside it. On a phone the label is small, so when in doubt, scroll past the first result.

What should I do if someone clicked a fake ad? If they only looked, close the page. If they typed a password, change it and turn on multi-factor sign in. If they ran a download, disconnect the computer and have it checked for password stealing software.

Does an ad blocker help? It can, because it hides sponsored results before anyone clicks. It is not a complete fix, so keep the habits above as well.
