Index out of range on start, causing crash

[micah]

Using current head of the branch, when I try to run the exporter, I get this error:

 panic: runtime error: index out of range [2] with length 1
 goroutine 26 [running]:

I am getting this error as well when the exporter is unable to connect to the clamav service which is down
