Hi Tinman57 welcome to Avast! Forums.

Hmmm… I did a couple tests and I could not reproduce your problem. I blocked my Internet access with my Comodo and disabled all Avast! shields then I enabled everything back and all was well.

Repair Avast! and try again.

Start > Control Panel > Add & Remove programs > select Avast! and click " Change/Remove ". Look for " Repair " and then “next”. Reboot when it is done.
