Does Your Computer Have A VIRUS? | What Is A Computer Virus? | The Dr Binocs Show | Peekaboo Kidz

Computers use code, a set of instructions, to function. While usually helpful, these codes can be programmed into harmful software called viruses that can make your computer 'sick'. Like biological viruses, computer viruses are small, invisible entities that can infect devices, slowing them down, crashing them, deleting files, or stealing personal information. They can also self-replicate and spread rapidly.

Thousands of viruses exist for malicious purposes, including Trojan horses, worms, and spyware. Devices can become infected by opening suspicious email attachments, downloading software from unsafe platforms, or visiting infected websites. Unethical hackers can also intentionally put viruses on computers, potentially holding them hostage for money.

To protect against viruses, install antivirus software, avoid clicking on untrusted links or downloading files from unverified websites, and never open email attachments from unknown senders. Always be cautious about sharing personal information online, use strong and unique passwords, and be careful when using public Wi-Fi, avoiding logging into accounts while connected.

The first computer virus, called the 'brain virus,' was created in 1986 by two brothers in Pakistan to prevent software piracy.
