Comodo blocks internet access until it is established, perhaps ST is trying to connect to check for updates.
There are many forum members using Comodo firewall and possibly a few of those using ST I haven’t heard of this blocking in the forums before. Have you tried the comodo forums ?
Other options if you are using winXP AVG anti-spyware (formerly Ewido) Resident scanner during trial On-Demand after trial ends. Or SUPERantispyware On-Demand only in free version.
