What is Malware?
What is Malware?
Malware is an umbrella term for malicious software designed to harm, exploit, or extract sensitive data from a system, device, or network. For example, cybercriminals use malicious software to access sensitive information they can use for financial gain. Stolen data can include anything from your payment details to your medical records, passwords, and more.
How Do I Get Malware?
Malware is commonly spread by visiting suspicious websites, downloading files, or emailing. Here are some other ways malware can find its way into your devices.
Phishing emails trick a victim into clicking on a link or opening an attachment that contains a malicious file. These emails appear to come from friends, trusted sources, or reputable organizations. Once opened, however, the malware code runs and starts carrying out actions on your system.
Infected USB Drive
Infected USB drives are used whenever an attacker needs physical access to a computer. Once plugged into your device, an infected USB drive auto-executes the malware code.
Malicious advertisement is a tactic that attempts to distribute malware through online advertisements. It typically involves cybercriminals injecting infected ads into legitimate advertising networks displayed on websites we trust. While some malicious ads require you to click on them to get infected, others can infect you automatically as soon as the page loads.
Fake Software Installations
You may think you found a movie, song, or software for free, but in reality, you fell for bait that downloads malware to your computer.
While apps available on an official app store are usually safe, some come from less legitimate sources that can contain malware.

If your hard drive is working excessively when no other programs are running, you should scan your system for malware. Similarly, if you see unrecognized changes or files generated on your computer, this can indicate a malware infection.
if you have ads unwanted ads pop up frequently, it may be a sign of adware or scareware.
If your browser frequently takes you to websites you intend to avoid visiting.
Types of Malware
There are many types of malware, and understanding the different types can help you better protect your devices. Here are some of the most common types:
A virus is a program that self-replicates by inserting its code into other programs. Viruses are distributed via emails, websites, or flash drives and activate when a victim opens the infected file. Viruses can lead to deleted or encrypted files, modified applications or malfunctions.
Ransomware is a malware designed to block access to a computer system until a ransom is paid. Then, hackers demand cryptocurrency for the decryption key that allows you to re-access your data.
Scareware is a malware tactic that manipulates users into downloading malicious software. It usually comes in pop-up ads that impersonate anti-virus companies informing you that your system’s files have been infected. This tactic takes advantage of a user’s fear to pressure them into buying fake anti-malware software.
A computer worm is malware reproducing and spreading from system to system without human assistance. Worms can exploit security software vulnerabilities, steal sensitive information, corrupt files, and install backdoor access to a system. They also utilize a large amount of memory, so affected computers and servers can overload and fail to respond.
Spyware is software designed to capture your activity and sensitive information without your knowledge or consent. Your information is then relayed to data firms and advertisers or sold on the dark web for profit.
A trojan, or trojan horse, is malware disguised as legitimate software. Many modern forms of this malware allow cybercriminals to create a backdoor in your computer system that gives them unauthorized access. Unlike worms or viruses, trojans do not replicate themselves but are often used in ransomware attacks to access users’ sensitive information.
Adware is software designed to serve advertisements to you, either within your web browser or in other programs. Adware isn’t always bad. Some free apps, for instance, include adware to make revenue from ads. Malicious adware, however, bombards you with infected ads that harm your computer.
Rootkit is a form of malware that provides hackers access to control a target’s computer or smart device. Anything with an operating system is a potential target for this particular malware.
A keylogger is another malware that records the user’s keystrokes on a keyboard. The cybercriminal uses this gathered information to access personal accounts and information.
