I think I see what's happening here.  Let's take a closer look at that  
second line, which chains three different commands:

grep 'Milter add: header: X-Virus-Status: Clean' maillog | grep -v  
Clean | wc -l

Command 1: grep 'Milter add: header: X-Virus-Status: Clean' -- search  
for and print all stating that "X-Virus-Status: Clean" was added to a  
message.

Command 2: grep -v Clean -- filter out all lines which mention the  
word "Clean"

Command 3: wc -l -- count results

Given that every line produced by the first grep will meantion "Clean"  
and thus be filtered out by the second, a result of 0 lines is always  
going to happen.

I suspect you intend something more like this:

grep 'Milter add: header: X-Virus-Status:' maillog | grep -v Clean | wc -l

Notice that this time the first grep will catch any line adding an  
X-Virus-Status header, not just those with a "Clean" result.
