Are you seeing the same shopping ads on every website you visit? They might not be ads at all, but "adware." Adware is malicious software (malware) that injects ads into web pages in such a way that they can't be blocked. The only way to get rid of these ads is to remove the malware.
Step 1: Look for and remove malware extensions in your browser
Chrome and Opera
Type about:extensions in the address bar to open the list of extensions. Remove any extensions that 1) you don't remember installing or 2) you recently installed (say, just before those ads started appearing).
Choose Safari > Preferences > Extensions and remove any extensions that 1) you don't remember installing or 2) you recently installed (say, just before those ads started appearing).
Type about:addons in the address bar, select Extensions, and remove any extensions that 1) you don't remember installing or 2) you recently installed (say, just before those ads started appearing).
Microsoft Edge doesn't have many extensions yet. If you suspect Edge has been infected with malware, it's most likely not because of a bad extension.
Step 2: Root out malware in your operating system
To remove the malware from your computer, follow the instructions in The Safe Mac's Adware Removal Guide.
The name of the malware is usually found at the bottom of the block of ads in small gray letters. For example, you may see something like "Savings-Magnet" or "Ads by Shopping Deals." (See some examples of adware.) Search for the name of the malware on Malwaretips.com to find the appropriate removal guide.
You can also ask for help in Malwaretips.com's Malware Help forum.
By the way, be sure you're on the real Malwaretips.com site! Beware of "copycat" sites such as Malwaretips.org, which are scam sites designed to push a particular "malware removal" product.
To remove the malware from your Chromebook, follow the instructions in this post on the Google Chromebook help forum.
Step 3: If all else fails, check your wireless router
If you've tried everything we suggest and those ads aren't going away, your wireless router might have been hacked. Here's some information about how that can happen, what to do if it does, and how to prevent it from happening again:

If you're suddenly getting more spam email after a malware infection
If it feels as if you're getting more spam or junk email than normal after your computer has been infected with malware, it might not be your imagination. Thanks to that malware, your email address may have made its way onto the list of every spammer on the Internet.
You can try contacting your Internet Service Provider's customer support team. They may be able to tweak your spam filters to catch more of these unwanted emails.
We found an article with advice on how to stop spam from invading your mailbox. Hopefully, it will help to stop at least some of it. The other option, of course, is to get a new email address. But that cure might be worse than the disease. :)

How did I get it?
How did you get the malware in the first place? Sometimes it's by downloading a desktop application or installing a browser extension that begins secretly directing you to pages filled with ads (or worse). You can also get malware by visiting a site that is serving infected ads (often without the site owner's knowledge).
