Malware can also be used to hijack your computer and use it to launch attacks against other systems. Viruses can spread quickly and easily. They can infect your computer and any files that you share with other people. Phishing attacks can trick you into revealing sensitive information, such as your passwords or credit card numbers. Identity theft can occur when criminals gain access to your personal information and use it to commit fraud or other crimes.

When you click on a random ad, you could be exposing yourself to these dangers. It is important to be cautious when you browse the Internet and to only click on ads from trusted sources. If you suspect that an ad may be malicious, you should avoid clicking on it.
