Malware includes programs such as viruses, trojans, spyware, and ransomware.
- Viruses infect one computer, copy themselves, and then spread to other computers.
- Trojans are malicious programs disguised as legitimate software.
- Spyware are programs that can monitor your activity, redirect your computer to unwanted websites, or steal information such as passwords, credit card numbers, and even your identity.
- Ransomware is a type of malicious software that prevents users from accessing their system or personal files and demands ransom payment in order to regain access.
- Viruses and other malware often provide a conduit through which cyber-criminals can access and steal information or control your computer.
To keep your computer running efficiently and to protect your personal information:
- Be aware that malware like viruses can exploit both computer software vulnerabilities and human vulnerabilities via social engineering to infect your computer.
- Keep your computer software up to date and use malware protection products, such as Windows Defender, Malwarebytes, and Sophos antivirus.
- Be vigilant when searching the Internet, browsing websites, and opening e-mail attachments. Malware protection software can only protect you from known malicious software.
- Never install or run software from untrusted sources.
- Do not open suspicious email messages, links, or web pages. If you are unsure, verify the source.
- Limit your use of flash drives. Never use them on public or untrusted systems. Likewise, never plug untrusted flash drives into your own computer.
- Always scan external devices such as USB storage before using them.
