Whois & Analysis for emsisoft.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.

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.

In computer security a threat is a possible danger that might exploit a vulnerability to breach security and therefore cause possible harm.

Software bloat is a process whereby successive versions of a computer program become perceptibly slower, use more memory, disk space or processing power, or have higher hardware requirements than the previous version—whilst making only dubious user-perceptible improvements or suffering from feature creep.

The term is not applied consistently; it is often used as a pejorative by end users (bloatware) to describe undesired user interface changes even if those changes had little or no effect on the hardware requirements.

In long-lived software, perceived bloat can occur from the software servicing a large, diverse marketplace with many differing requirements.

Most end users will feel they only need some limited subset of the available functions, and will regard the others as unnecessary bloat, even if end users with different requirements do use those functions.

A mobile device (or handheld computer) is a small computing device, typically, small enough to hold and operate in the hand and having an operating system capable of running mobile apps.

These may provide a diverse range of functions.

Typically, the device will have a display screen with a small numeric or alphanumeric keyboard or a touchscreen providing a virtual keyboard and buttons (icons) on-screen.

Many such devices can connect to the Internet and interconnect with other devices such as car entertainment systems or headsets via Wi-Fi, Bluetooth or near field communication (NFC).

Integrated cameras, digital media players, mobile phone and GPS capabilities are common.

Power is typically provided by a lithium battery.
