Malware is any malicious software deliberately designed to bring harm to a computer system, program, server, user, or personal computer network. There are a wide variety of malware kinds available, such as computer viruses, Trojan horses, worms, malware, encryption programs, ransomware, adware, and fake security applications. Malware often attacks computers without a user’s knowledge and permission. The malware can reside on the computer system or remotely via a connection to the internet. Many malware programs are spread through email attachments, chat rooms, bulletin boards, and peer to peer files. Malware can also develop through Trojans, backdoor applications, and browser vulnerabilities.
The term “malware” comes from the word “mal” meaning deceit and “ware” meaning an instrument or tool. Malware usually attacks a computer without the knowledge or permission of the user. It corrupts files and folders and then sends or results in the execution of other programs. Malware can affect all kinds of Windows-based computers, although it is most common to attack PCs running Windows. Some kinds of malware are capable of causing a computer to crash or to execute applications by exploiting a security vulnerability present in the operating system. Other malware can be programmed not to perform harm, but to display advertisements or track Internet surfing habits.
The most common kind of malware is adware.
Malware can infect a computer through the downloading of email attachments that appear to be from a trusted source, when in fact the email contains malicious codes. Some other kinds of malware are created by hackers with the intention of gaining access to a particular computer system or to obtain confidential or protected information. One type of malware is an adware that displays advertisements on a computer screen; other forms of malware are spyware that sends or places tracking information on a PC user.
Common types of malware are spyware (also known as malware), which collects data and sends it to someone else. Spyware can be used for many purposes such as controlling online activities and can be installed by using free software or by paying for commercial spyware removal programs. Spyware usually comes bundled with other programs such as adware or virus. Malware distributed through spyware can infect a computer without the permission or knowledge of the user. Some other forms of malware are worms that are transmitted through email attachments, security vulnerabilities found in websites, game players, dealers and even Trojans.
Worms are also considered malware.
They spread via file-sharing networks, email attachments, CD-ROMs, and FTP. There are many types of worms, ranging from simple viruses that infect programs and databases to malicious software capable of denying access to the Internet and damaging critical systems. Some worms are capable of spreading to other computers through the transfer of email attachments, infected website files, and media including photographs. Simple viruses can cause annoying messages to appear on the screen of your computer when you attempt to access the Internet and when you attempt to open a file.
Cyber-criminals use viruses and worms to hijack personal information and transfer them to their source. In order to distribute their malware, cybercriminals use command and control servers that operate automatically sending spam, pop-up ads, redirects and other malware to various computers. They can do this through email attachments and programs downloaded from the Internet. This means if you do not know which programs you have open on your computer you could unknowingly infect your system from cyber criminals.
Apart from installing malware on your PC you can also prevent it from spreading by having an effective anti-malware and anti-spyware program. You should get the latest anti-malware and anti-spyware apps from the Google Play Store or the Apple Store. Apart, from having these apps you should avoid downloading apps from unauthorized sources like ecommerce websites or apps that you downloaded from outside sources. Some malicious apps that are disguised as popular apps such as the android or IOS apps can also spread malware onto your system. The fake application may look legitimate but in reality it is a malware tool that will steal your confidential information.
So, if you have applications that are not from the Apple Store or the Google Play Store and if you have downloaded applications from unauthorized sites then you should protect yourself by removing them. You should not allow malicious websites to download programs onto your PC.
- You should make sure to delete all files associated with the apps and you should remove all live wallpaper that you have downloaded from the Internet.
- By performing disk and hard drive cleanup you can effectively reduce the risk of getting malware attacks.
- Disk cleanup also protects your PC against future attacks by freeing up your PC’s memory resources.
