During the night,AVG virus protection did an update secretly on Laptop windows 10 and this update put EZ builder.Exe into virus jail! Took me hours to figure out why it loads but then refuse to connect to EZB! so I tried my cell phone app Android and no problems then I tried my desktop PC with no problems ...but suddenly desktop AVG started an update and I caught it trying to say EZ Builder.EXE looks like a rare harmful file and needs to be submitted to the AVG Labs for 24 hour Analysis to prove it is safe?LOL! I shut that rainbow AVG down and stopped it from screwing up my desktop EZ software! Went back to my Laptop and shut down AVG and Bingo EZ Builder connected back to my robot!
