More examples of screen lockers are XinFrams, BlackKnight2020 and SSHBOT. As a rule, malware of this type lock the screen and displays a ransom note with instructions on how to contact its developers, pay a ransom and/or some other information. Most of the times screen lockers do not encrypt user's files - they are classified as non-encrypting malware. Although, some of them do encrypt files (and lock the screen).
How did ransomware install on my computer?
Trojans are malicious programs that can be used to proliferate malware by designing them to cause chain infections. Once certain Trojans are installed on computers, they infect those computers with some other malware (e.g., ransomware). Unofficial software activation ('cracking') tools tend to be designed to install malware too. Mostly because there are popular amongst users who are not willing to pay for activation of licensed software and seek to activate it with unofficial tools. Fake software updating tools infect systems by installing malware instead of updating some installed software or by exploiting bugs, flaws of some outdated software that is installed on user's computer.
How to avoid installation of potentially unwanted applications?
Files, programs should be download from official sites and via direct links. Tools, sources like unofficial pages, P2P networks, third party downloaders (and installers), should not be used. Website links and attachments in irrelevant emails that are sent from unknown, suspicious addresses should not be opened as well. Emails of this kind tend to be used to trick recipients into downloading (and opening) malicious files. Any installed software has to be activated (and/or updated) with tools or implemented functions that are provided by its official developers. Third party, unofficial tools can and often do install malware, also, it is not legal to activate licensed software (including operating systems) with unofficial tools. A computer should be scanned for threats regularly, it is advisable to use a reputable (and up-to-date) antivirus or anti-spyware software for that and keep it up to date. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
