Malware is any type of software that is designed to damage your computer or gain unauthorized access to your personal information. It includes viruses, worms, Trojan horses, and spyware. Most malware is distributed over the Internet and is often bundled with other software.

The best way to guard against malware is to install antivirus software, such as Bitdefender, Norton, or Kaspersky. Antivirus software helps to prevent malware from being installed, and it can also remove malware from your computer.

It's also important to stay smart when you're browsing the Web or using email. If a website or email attachment looks suspicious, trust your instincts. Keep in mind that your antivirus program may not catch everything, so it's best to avoid downloading anything that might contain malware.
