Ransomware is a refined piece of malware that blocks the victim’s access to their files, and the only way to regain access to the files is to pay a ransom.
In other words, ransomware Ransomware is a form of malware software that locks up the files on your computer encrypts them, and demands that you pay to get your files back. When a system becomes infected, a pop-up window opens, offering you to pay for the recovery of all of your files within three days, with a countdown timer to the left of the window. if you fail to pay within that time, the fee will be doubled, and if you don’t pay within seven days, you will lose the files forever. Payment is accepted only with Bitcoin
How is Ransomware Spread?
Ransomware spreads faster when it hits unpatched or older software. It is spread by an internet worm — software that spreads copies of itself by hacking into other computers on a network, rather than the usual case of prompting unsuspecting users to open attachments. The cyber attack was carried out with a tool stolen by the United States National Security Agency (NSA).
How to prevent Ransomware?
The best way to prevent ransomware is to take regular backups of your files on the computer. The virus only affects files that exist on the computer. If you have a backup of your files and your computer is getting infected with ransomware then just clean your computer remove all software and files reinstall all software and restore all files from the backup.
Other precautions like regularly updating your antivirus program, enabling pop-up blockers, updating all software from time to time, and avoiding opening suspicious attachments can prevent your computer from getting infected with malware.
