One | MT4

My antivirus thinks that the MT4 installation is a virus.

The MT4 terminal has a built in protection system that prevents recompilation of the software.

Some antivirus applications think that this is a virus but it is not.

You should add “terminal.exe” to your antivirus white list or exception list, to avoid deletion.

This is a known MT4 error and not exclusive to One Financial Markets. It is currently being investigated by MetaQuotes.

If you require any further assistance please contact

Why does MT4 show me ‘Common Error’?

The message 'Common Error' can be displayed to show a number of errors. Most frequently it is displayed when your internet connectivity is slow or is being interrupted by something such as antivirus software or other users sharing your internet connection.

  • Try temporarily disabling your antivirus or internet security.
  • If you have another computer, try it on there to rule out a PC issue.
  • If you have access to another internet connection, try that.

If you still can’t solve the issue please contact providing as much information as you can.

I can’t login to MT4. I get the error message 'Invalid Account’.

The login credentials (username and/or password) you are using are incorrect.

In the first instance we would recommend  trying again, copying and pasting from your Welcome Email. If you are still having problems please contact who can check your account password. Please make sure you e-mail them from your registered e-mail address and provide them with your account number and password.
