To defend/prevent your network from attack you should do the following: Update all workstations, laptops, & servers with the latest security updates by running windows update and installing any security related patches. If you are a Syscon Managed Services client that subscribes to our Windows Update Service, then this has already been done for you. Update all Anti-Virus software to the latest release and verify that your systems are running the latest virus definition files. If you are a Syscon Managed Services Client, our remote monitoring constantly checks to make sure your Anti-Virus Software is up to date and you have the latest virus definitions available. Use a firewall to block all incoming connections from the internet to services that should not be publicly available. Update any available firmware and filter software and use complex passwords for your user accounts. What to do if you think one of your PC’s is infected: Immediately remove the infected device from the network. You can do this by unplugging the network cable from the back of the computer. Boot your operating system to safe mode and run a full virus scan using the latest Virus definition files available to your Anti-Virus Software. If an infection is found, most Anti-Virus software will automatically remove the threat. Once the threat is found and removed you will need to reboot your computer to completely remove the virus. If your software does not automatically remove it, there are several removal tools available from the major Anti-Virus Software Manufactures that you can download and use.
