Ransomware locks your files and demands you pay a ransom to unlock and access them again. This type of malware is rapidly becoming more advanced. It can immediately start deleting files as soon as you are infected, pressuring you to pay up. One of the most common ways that ransomware can access your computer is through phishing. Phishing uses email as a weapon, disguising itself as a legitimate email and tricking the user into opening the email or attachment.
