The social networking company has been hit by a cyberattack, and it has announced plans to ban all users from using the account.
The account has been used to spread malware, infect machines and upload files that have infected users around the world, according to the company.
The breach is thought to have been carried out by the Chinese government, which has claimed responsibility.
“This is the largest cyber attack ever observed by Facebook and we are taking the necessary actions to help ensure that it doesn’t happen again,” the company said in a statement.
“We know that this type of attack can be a dangerous experience for some people and we want to make sure everyone has the right information and tools to protect themselves.”
Facebook is known for a number of other security flaws that allow malicious code to spread, such as its “Find friends on Facebook” feature, which can be used to locate and share information about the people who are friends on the platform.
The company said it had deployed a “secure network” to protect users and that it had increased the number of employees at its worldwide security team.
It also said it would create a new cyber-crime taskforce that would focus on “advancing its cybersecurity efforts and developing better solutions for governments, companies and other organisations”.
The company will also offer a one-time free trial to all users of its social network and other services.
Facebook said it was aware of a security vulnerability in the account, and that an update would be rolled out on Monday.
“Facebook is taking the security of our users very seriously, and we have rolled out a security update that will provide the ability to access the Facebook account from within the app.
We are currently working with our partners to implement this update, but it should be available soon,” it said.
