Hello Bartleboom, Beammeupscotty, Avast Support, & anyone else suffering with this Bank mode system freeze problem. After over a year or two of annoyance & frustration with this problem, all the while researching & trying everything I could think of to fix it, I was finally led to a workaround: I activated the Hyper-V virtual machine in my Windows 10 Pro, installed Avast Premium Security & Secure Browser on it, & went into Bank Mode from there. After many sessions over several days, which previously would have frozen my PC many times, I am happy to report NOT ONE FREEZE!!! Alleluia!... life is good!
