Firewalling stuff it shouldn't

Hello,

I teach online using BlackBoard Collaborate, I’ve taught weekly for well over a year now. Last week I logged into my classroom, started uploading all my slides and such and after about 45 minutes, I checked back to find that I’d been kicked out. I tried to re-enter a bunch of times and it error’d me out each time, wouldn’t do it. Had to use another computer to teach with, lots of associated problems, blah blah.

This week. Logged into classroom, everything loaded up, teaching the class…about 45 minute into CLASS (not just prep as before), I get kicked out. Again it won’t let me back in. I tried to go to the Blackboard support site but it wouldn’t connect me…it finally did and I got on the phone calling BBC support while at the same time attempting another log in…wouldn’t you know it, this time I got in ok. Finished up the class but lost a good 10-15 minutes. Can’t have this!
BBC tech I chatted with afterwards is convinced it’s due to Avast and told me to disable it the next time before I log into my class. I’ve used this same computer with Avast for over a year to teach and never had this problem…did Avast update between Oct. 22 and 29 to possibly be causing this problem?

I’ve never heard of an intermittent firewall block. A firewall either blocks or allows.
Suggest you check with phone co. support and maybe ask for a more competent helper.
