How did DiamondFox infiltrate my computer?
Cybercriminals distribute ransomware via unreliable sources for downloading software by disguising malicious files as legitimate and way until someone will download and open them. Users who open those files infect their computers with malware. Some examples of sources that can be used to trick users into downloading malicious files are Peer-to-Peer networks like torrent clients, eMule, free file hosting pages, third party downloaders, freeware download websites, and unofficial pages. Unofficial software activation ('cracking') tools are illegal tools that are supposed to bypass the activation of licensed software. It is common that cybercriminals take advantage of their popularity and use them to distribute malware. Fake tools for software updating damage systems either by installing malicious software instead of fixing, updating the installed one, or by exploiting bugs, flaws of software that is out of date.
How to avoid installation of malware?
To avoid installation of ransomware or other malware, do not open attachments or click links in received emails that are not relevant and sent from unknown, suspicious addresses. Update and activate installed programs with tools or implemented functions that their official developers provide, and not some third-party, unofficial tools. Such tools often contain malware, and it is not legal to use them to activate licensed software. Download files or software only from legitimate, official websites and via direct download links. Avoid using other sources, channels such as third party downloaders, unofficial pages, third party to downloaders, etc., or third-party installers. And lastly, run virus scan regularly. It is advisable to run them with a reputable antivirus or anti-spyware suite. If you believe that your computer is already infected, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate infiltrated malware.
