First you don't need the echo (just like the cat that someone else had
proposed). I think that it is more of an aesthetic than a
processor/memory use issue these days...

However
awk '{print$5}' "Antivirus Pattern - Win vx.yyy.z" | tr -d '.' | cut -c 2-
will fail in the same way that the earlier egrep solution did.
