What is Malware and How Does it Affect Your Computer?
Viruses, worms, Trojans and other types of malware are malicious programs designed to do harm to your computer. These programs often steal personal information and interfere with your computer’s normal functioning. Some programs even encrypt your files and demand a ransom in order to decrypt them.
In addition to stealing information, malware also makes your computer more susceptible to other threats. Malware can cause your system to suddenly slow down, and may send information to a remote location.
Malware has also grown increasingly complex. New techniques have been developed to deceive antivirus programs and antimalware software. It can also modify its own underlying code.
Some types of malware have been designed to manipulate the user’s web browsing experience. Some of these adware programs display pop-up or banner ads to the user. Others are free games and browser toolbars. Adware can greatly disrupt your computer, though some forms of adware are considered legitimate.
Malware can also take over device processing resources. It may also download additional content and alter settings on your computer.
Some malware uses a command-and-control server to allow threat actors to communicate with infected computers and devices. It can also coordinate distributed denial-of-service attacks. These attacks often use a botnet of enslaved computers.
Another type of malware is adware, which tracks the user’s browsing activity, download history, and other personal information. Adware can also be used to extort payment for access to infected computers.
Malware may be delivered to an infected computer through drive-by downloads or file-sharing software. It can also be installed by using removable media.
