Malware is malicious software that gains access to your computer to cause harm and destroy your system. Malware can present itself in many forms such as viruses, Trojan horses, worms, adware, spyware,andransomware. All forms of malware are designed to compromise the safety of your devices and the data stored on them. This might allow hackersto access your personal data and, in some cases, use that data to commit identity theft, cause damage, or corrupt the system for financial gain.
Worms are a type of self-replicating malware that spreads itself quietly over a network of computers which leaves those computers at risk for other harmful malicious software.Whereas other threats to IT Security, such as phishing scams, use social engineering to hack into a system, a worm, much like their real-lifewiggly counterparts, find seams in the computer’s operating system that allow itself to install and replicate. It also then can follow known holes in networking and file transfer protocols.
However, because these vulnerabilities in an operating system are patched by vendors with relative frequency, the code written for worms often have a short shelf life.
Simply put, Malware is a whole can of worms that you don’t want to open. (We apologize for this pun, but we couldn’t resist.)
