What is Malware
“Malware” is a general term for any software that performs unwanted tasks on your computer. Malware can range from annoying pop-up advertising, to malicious software such as viruses that are intended to cause damage and steal data.
How does it spread?
Malware has grown in sophistication and is now spread through a variety of clever techniques including malicious email attachments and infected websites. In some cases, malware is even installed by the user unknowingly by clicking on pop-up ads or by installing software that comes bundled with “other software”.
What does it do?
Once ransomware has been installed on a computer, it will encrypt files on the computer as well as data on files servers like Opal or Knox. Once it has finished encrypting files, a message will be displayed for the user with instructions for retrieving lost files. In some cases the message will imply that the FBI, US Department of Justice, or some other government agency encrypted your files due to illegal activity. In other cases, the criminals will state up-front that they have illegally encrypted your files and the only way to retrieve them is by paying the ransom.
