Going Old School with This Morning's Forecast

It appears someone in the WLTZ (Columbus,GA) Weather department may have been using the computer to surf for more than low pressure systems. 

The station's weather computer has a virus and morning Weatherman Miller Robson is going old school with the forecast. 

Robson was spotted putting the weather info on white boards for his morning forecast. 

Now, just how did that computer get a virus?
