If the printer keeps advertising, it may be because some software or plug-ins have installed advertising programs or plug-ins on your computer. In this case, you can take the following ways to deal with it:

1. Uninstall unnecessary software or plug-ins.

You can find the installed software or plug-in in the control panel and uninstall it. If you are not sure how some software or plug-ins are installed, you can use security software to scan your computer and detect potential adware and plug-ins.

Use an ad blocker

Using an advertisement blocker can effectively prevent advertisements from popping up and protect your computer from potential threats. This interceptor can stop the pop-up of advertisements and prevent websites from downloading malicious software. You can find the ad blocker in the browser store.

3. Upgrade your browser

If your browser version is too old, there may be some loopholes in your browser. Malicious advertisers may exploit these vulnerabilities to invade your computer. Upgrading the browser can solve these problems.

4. Update your antivirus software program regularly.

Updating antivirus software programs regularly is an important measure to protect your computer security. Regular updates can keep the database and other functions of antivirus programs up-to-date, thus preventing adware and other malicious software from invading your computer.
