How to remove the FormBook virus from PC?
Computer security is tested daily by hackers around the world. Companies spend millions on digital security, and consumers may be constantly exposed to malware threats that have evolved to insecure viruses such as the FormBook virus trojan.

What is FormBook virus?
The FormBook virus is a type of malware that misleads the user.
The FormBook virus masquerades as a legitimate program. The Trojan virus is harmless, but it is dangerous because it allows cybercriminals to get into the user's system. When a Trojan virus activates, it starts spying, collecting valuable data, and sending it to criminals.
In today's world, there are many more varieties of Trojans. Viruses know how to find the path to the user's computer to gain complete control over it. Also, FormBook virus collects information about the system to detect vulnerabilities. All collected information is further used to create ransomware, other viruses, and programs.
