Protect Your PC against Malware

To help protect your computer from the Sirefef malware, perform the following steps:

1. Keep Current with Operating System Updates -- Important system updates provide significant benefits such as improved security. Not keeping up with operating system updates will make your PC vulnerable to malware threats such as Sirefef. Ensure you use the Automatic Updates feature in Windows and have your computer automatically download Microsoft security updates.


2. Use an Antivirus Software -- Even though Sirefef can disable antivirus applications once it has been installed on your machine, having an antivirus application installed prior to becoming infected with the malware can help prevent infection. You must update the antivirus application with the latest signature files.  Out-of-date signature files will be render the antivirus application useless not only against Sirefef, but against other malware such as the FBI virus.


3. Be Cautious of the Websites You Visit -- Keep away from unknown sites and don't click on links within emails unless you're absolutely sure it's safe to do so.


4. Don't Download and Install Pirated Software -- Sirefef is often distributed by exploits that promote software piracy. Pirated software can introduce other threats, such as the Suspicious.Emit malware.
