Malicious software, commonly referred to as malware, is software and/or
program code/instructions inserted into a system, usually covertly, with the
intention of compromising one or more of confidentiality, integrity, or
availability associated with the system or the data it processes. A cyber
criminal may use malware to steal information or carry out malicious
activities. Malware is an overarching term that encompasses more traditional
virus, worm, and trojan software, as well as modern ransomware,
droppers/payloads, rootkits, and sniffer/logger threats.
How do you get malware?
The two most common ways for malware to be installed on your device are by
accidentally downloading it while trying to download legitimate software, or
through a phishing attack. In both instances, there are easy steps to take
to protect yourself.
How to protect yourself
Be aware of downloads
Be vigilant when downloading software, or documents. If you are
downloading something from the internet, ensure that you go to
legitimate sources. You may also be able to cryptographically validate
the source of some software. Cyber criminals can make fake websites that
look very convincing. Ensure you always check that the web address
(URL) is accurate and look
for spelling errors or incorrect logos before downloading anything.

automatically scan other software and documents before they are
downloaded to your computer. You can also set it up to scan your device
at regular intervals.
