d) Name three common ways that malware can gain access into a computer system. How can one get rid of malware?

Three common ways malware can gain access:

1. Phishing/Social Engineering: Tricking users into opening malicious attachments or clicking on infected links in emails or messages.
2. Exploiting Software Vulnerabilities: Taking advantage of unpatched security flaws in operating systems, web browsers, or other applications.
3. Malicious Downloads/Drive-by Downloads: Downloading infected software from untrusted sources or unknowingly downloading malware when visiting compromised websites.

To get rid of malware, one can:

• Run a full scan with up-to-date antivirus/anti-malware software.
• Disconnect from the internet to prevent further spread or data exfiltration.
• Remove detected threats and quarantine suspicious files.
• Update the operating system and all software to patch vulnerabilities.
• Perform a system restore to a point before the infection, if available.
• In severe cases, a complete reinstallation of the operating system may be necessary.
