If your PC might already be infected

  1. Unplug your computer from the network.
  2. Obtain a copy of McAfee AVERT Stinger. It detects and removes the most recent viruses. Go to a computer lab and save it to a floppy or contact the Computer Help Center for a CD-ROM.
  3. Run Stinger and clean any viruses found.
  4. If your computer appears to be working normally, reconnect your machine to the network and install Cortex Antivirus. If you are not sure if the problems are fixed, do not connect your machine to the network and contact ResNet or the Computer Help Center for more information.
  5. Visit Windows Update and make sure you have ALL critical updates installed.
  6. Run a full system scan with Cortex Antivirus.
  7. If you still have problems after completing these steps or if you have any questions, call ResNet at 402-472-3535.
