Remote-access Trojans (RATs) is a galloping concern among common people across the world.
Malware that secretly installs tools similar to those used by network admins to control machines remotely. Once the malware is installed on a machine, cyber pranksters can take control of the entire system, including the webcam.
Many have heard the stories about people being spied on using their own computer or people being blackmailed using embarrassing or incriminating video footage unknowingly recorded from compromised webcams.
According to leading AV and security solution provider, creepware programs, such as Pandora RAT, allow an attacker to gain access to files, processes, services, the clipboard, active network connections, the registry and printers. Some programs also allow an attacker to remotely control the desktop; take screenshots; record webcam footage; record audio; log keystrokes; steal passwords; download files; open Web pages; display onscreen messages; play audio messages using the text-to-speech function; restart the computer; and cause system failure.
To stay protected against creepware or any other 'X'ware, keep antivirus definitions, operating systems, and software up-to-date, and avoid opening emails from unknown senders or clicking on suspicious email attachments. Users should also exercise caution when clicking on enticing links sent through email, instant messages, or posted on social networks, and only download files from trusted sources.
Also be suspicious of unexpected webcam activity. When you're not using the webcam, keep the shutter closed..!
Fairly simple one is to check the System Properties (Right-click My Computer, and then click Properties) or from BIOS (before the computer boots)
Windows key + R will take you to Run Command and type Msinfo32
