In case you detect FormBook Malware, do not hesitate to use the instructions of the guide that we have provided and remove the Trojan immediately.

The FormBook Malware

The FormBook malware is a type of malware that nobody wants to have on their PC even for a minute. The FormBook malware is so tricky and so harmful, that it can be kept responsible for more than 70% of all the malicious infections that happen through the Internet.

After crashing into the victim’s computer, for instance, a Trojan may destroy the entire system. Yes, we really don’t overestimate it because a Trojan horse is capable of destroying important files, damaging Windows logs, stealing of personal information, and also installing more malicious software. According to the data at our disposal, the FormBook Malware virus could be used as a potential transmitter of various nasty viruses including the most famous Ransomware threats.

This malware may also be exploited by the hackers as a tool that can provide them with remote access and let them steal sensitive information from you such as your passwords, login credentials or bank account details. If you don’t want to become a victim of a crime of such type, you definitely should remove the infection the moment you detect it. But how can you know if your computer is infected with FormBook Malware? Here are some possible signs you should observe:

  • The computer starts to work extremely slowly;
  • Programs do not open or stop working shortly after they have been opened;
  • Complicated and aggressive pop-ups appear on the screen, even if the user does not surf the web; they usually report that your computer is highly infected and offer you to install a malicious malware program to “fix” all the problems;
  • Web browsers become unresponsive and unexpectedly start redirecting you to suspicious web pages.
  • Frequent system error messages and crashes start to appear

Unfortunately, it is very difficult to detect and remove FormBook Malware manually because it usually gets disguised as a safe system process or a file. In addition, this Trojan horse may disable the computer security programs and may pass through the Windows Firewall and most of the non-reputed antivirus programs. To catch and remove this threat, we recommend that you scan your computer with a reliable anti-malware program that can detect this virus. We suggest you use the professional removal tool for that. Alternatively, you can follow the instructions in the removal guide below and try to eliminate the infection manually. Just make sure you carefully detect the correct malicious files and delete them all.

How is FormBook Malware distributed and how to protect yourself?

Trojan horses, unlike other viruses, are famous for their creative distribution and infection techniques. Typically, the cybercriminals distribute them via email or social media messaging, peer-to-peer file sharing programs, or just through download links, placed on an insecure web page. Yet, the most popular and effective way to spread viruses like FormBook Malware is by directly sending the victims an infected email. The cybercriminals usually send misleading messages that prompt the user to open an attachment, typically masked as an official document, such as a court notice, invoice, resume or account. The email service providers usually try to filter out these messages as Junk/Spam, but some fraudulent emails may pass through spam filters successfully. That’s why, before opening an email, check that the sender is familiar to you. If it is not, do not open such letters and the attachments contained therein. Try to use your common sense to keep away from any potential malware transmitter because it is certainly better to avoid them than dealing with their devastating effects.
