Sorry Tmor, I don't quite get what you mean with "catching" and "on the ASL itself" .. Since the Blaster/Lovesan worm are using Windows RPC wulnerability to spread, there will be no notification from the AV tool or anything else. But, in general, the ports 135, 139 & 445 will be rejected & logged. Regarding those ports, we received following amount of attempts to these ports during August so far: 135/ 1000+, 139/ 500+, 445/ 2000+. I have not analyzed this from earlier months, so I don't know if there's any increase.
