Si-chao.cstools.facebook.com is a creation of people with malicious intentions. This program has malicious features that can cause various types of harm. Once it nests inside your system, the malware may secretly collect various types of sensitive data, keep tabs on your keystrokes, hack into your webcam or mic, modify, delete and corrupt different files on your system, and even insert other malware such as Ransomware or Rootkits without your knowledge.

In addition, Si-chao.cstools.facebook.com may screen the victim’s desktop, access the personal data of its victims and obtain sensitive personal information. Any such personal data collected in this way may later be used in various criminal schemes and agendas. Keep in mind that the cybercriminals pursue the greatest possible benefit. Therefore, they can use the obtained personal and sensitive information for a variety of crimes, including blackmailing, money theft, banking fraud and more. All in all, the presence of a Trojan can lead to serious privacy problems and severe system damage. Therefore, if you have recently opened some suspicious attachment added to a junk mail and believe that your system may be infected, we advise you to scan the system with a professional malware removal tool and remove all detected threats.

How can Si-chao.cstools.facebook.com infect you?

According to research, the criminal developers spread Trojan infections in spam email campaigns, malicious advertisements, cracked software, torrents, and compromised websites. However, of all the different distribution methods, the spam emails are some of the most effective and widely-used ones. Typically, the users receive random emails with misleading messages that encourage them to open the attached data. Once opened, those attachments secretly download and install the Trojan without showing any visible indications and without asking for any kind of approval from the user’s side. This way, the malware sneaks in the system unnoticed and gets down to its dirty business.

How can you prevent malicious programs from getting installed in the computer?

The main reasons why so many computers get infected with Trojans are the lack of knowledge and caution in the users, as well as the absence of reliable anti-malware protection. Therefore, the key to safety is caution and prevention. Start with paying more attention when surfing the internet. Think twice before opening attachments in spam emails, or in e-mails coming from suspicious email addresses. The next safety tip is to always have a reliable antivirus and antispyware solution installed and running.
