What is Malicious Software?
Malicious is the combination of two words, ‘malicious’ and ‘software.’ Generally, they were developed by the cyber criminals whom we call black-hat hackers to gain unauthorized access to the host system, steal sensitive data, and destroy computer systems.
Examples of commonly occurring malware are viruses, worms, Trojan viruses, spyware, adware, and ransomware. Recent malware attacks have surreptitiously stolen enormous data.
How to Protect Your Computer from the Malware?
Today, businesses emphasize preventive measures to offset the potential threat of data breach. However, the biggest mistake that companies make is just focusing on the security parameter. Eventually, despite all the preventive measures, some advanced malware makes its way to the system.
To cope with this problem, we strongly recommend you invest in technologies that consistently identify and detect malware, and that can evade all your preventive measures. Advanced malware protection entails multiple layers of safeguards coupled with high-level network visibility and intelligence.
How Do I Detect and Respond to Malware?
Malware will certainly penetrate your network. You must have an appropriate defensive system in place to ensure noticeable visibility and breach detection. To prevent your system from the disastrous impact of malware, you must detect malware quickly and act appropriately.
Whenever you identify a security loophole in your system, remove it immediately to offset the potential threat of malware attack. It is worth mentioning here today’s antivirus programs aren’t enough to combat advance cyber threats.
Without any ado, let’s delve deeper into malware types:
Viruses are a subcategory of malware. A virus is a malicious code attached to a document or file, and using macros, it executes its code and spreads from one computer to another. Upon downloading on your system, it remains standstill until you open a file and use it.
Viruses are specifically designed to hamper the system’s ability to operate. Besides, viruses can cause severe havoc and data loss.
Worms are malicious software that replicates in real-time and spread to other devices within the network. In stark contrast to viruses, worms do not require a host program to propagate.
Generally, worms infect a host computer via a downloaded file or a network system before it multiplies and starts replicating itself exponentially. Like viruses, worms can negatively affect the operations of a procedure, causing severe data loss.
Trojan viruses are advertised as helpful software program. Once the user accidentally downloads it on his system, the Trojan virus accesses sensitive data and can delete, modify, or block data.
This process could be insanely harmful to the performance of your system. Unlike virus and worms, the Trojan virus doesn’t replicate itself.
As the name spyware suggests, malicious software runs secretly on a computer and provides complete information regarding all your activities to a remote user.
What differentiates it from other malicious software is it doesn’t impede the system’s operations, spyware targets confidential information and provides remote access to intruders to your system.
Black hat hackers leverage spyware to steal secret financial information like credit card or your account number.
Commonly occurring spyware is a keylogger that keeps your keystrokes’ track record of stealing passwords and sensitive information.
