Windows 10 internet slow "resolving DNS host" ThinkOrSwim cannot connect to internet

For the last 3 days, my ThinkOrSwim app "could not connect to the internet".

Yesterday, they patched servers for ThinkOrSwim.  I think they may have applied the patch that allows a worm on the DNS server.

Today, I still could not open ThinkOrSwim.  My internet was super slow when connecting to FB, Youtube, etc.  Kept seeing the message "resolving DNS host".

I have Windows 10.  After doing these two things, my computer is really fast and I can now open ThinkOrSwim in a snap.

1) I noticed dropbox was executing in Task Manager.  Since I no longer use it, I uninsalled the dropbox program in the control panel programs.

2) I checked for Windows updates.  There was a new one since yesterday (8/18/2020).  I applied this update and rebooted.

My internet is now working really fast.

Hi @GaryInSanDiego 

We are sorry for the inconvenience. Kindly try excluding the Thineorswim.exe to firewall exlcusion and try again.
