Malware or advertising?

[neku]

Some of my devices are showing advertising when I open some websites or apps. Is this advertising intentional, or has some hacker downloaded malware on the smartphone due to which the ads are being shown?

It's normal for some devices to display ads when you browse certain websites or apps, but excessive or intrusive advertising can be a sign that something is wrong. In some cases, free apps or websites may include legitimate ads, but if you notice that the ads are very intrusive, appear in places where they shouldn't, and you have difficulty removing them, it could be a sign of malware. It's important to review which apps you have installed and remove any you don't recognize or that seem suspicious. I also recommend running a full scan with a reliable security app. Ads on legitimate sites aren't always dangerous, but if there's anything unusual about your phone's behavior, it's wise to be cautious and protect your information. Don't hesitate to seek professional help if the problem persists.
