Whois & Analysis for zemana.com

Ransomware is computer malware that installs covertly on a victim's device (e.g., computer, smartphone, wearable device) and that either mounts the cryptoviral extortion attack from cryptovirology that holds the victim's data hostage, or mounts a cryptovirology leakware attack that threatens to publish the victim's data, until a ransom is paid.

Simple ransomware may lock the system in a way which is not difficult for a knowledgeable person to reverse, and display a message requesting payment to unlock it.

More advanced malware encrypts the victim's files, making them inaccessible, and demands a ransom payment to decrypt them.

The ransomware may also encrypt the computer's Master File Table (MFT) or the entire hard drive.

Thus, ransomware is a denial-of-access attack that prevents computer users from accessing files since it is intractable to decrypt the files without the decryption key.

Ransomware attacks are typically carried out using a Trojan that has a payload disguised as a legitimate file.

Adware, or advertising-supported software, is any software package that automatically renders advertisements in order to generate revenue for its author.

The advertisements may be in the user interface of the software or on a screen presented to the user during the installation process.

The functions may be designed to analyze which Internet sites the user visits and to present advertising pertinent to the types of goods or services featured there.

The term is sometimes used to refer to software that displays unwanted advertisements known as .

Spyware is software that aims to gather information about a person or organization without their knowledge, that may send such information to another entity without the consumer's consent, or that asserts control over a device without the consumer's knowledge.

Malware, short for malicious software, is any software used to disrupt computer or mobile operations, gather sensitive information, gain access to private computer systems, or display unwanted advertising.

Before the term malware was coined by Yisrael Radai in 1990, malicious software was referred to as computer viruses.

The first category of malware propagation concerns parasitic software fragments that attach themselves to some existing executable content.

The fragment may be machine code that infects some existing application, utility, or system program, or even the code used to boot a computer system.

Malware is defined by its malicious intent, acting against the requirements of the computer user, and does not include software that causes unintentional harm due to some deficiency.

Antivirus or anti-virus software (often abbreviated as AV), sometimes known as anti-malware software, is computer software used to prevent, detect and remove malicious software.
