Systems (windows 7 x64 home/pro) are popping up with this beta version (11.1.2236) installed and they are quickly and consistently becoming unresponsive. They all experience the same issues; it starts with one random application hanging in the middle of an operation, then cascades to the entire windows operating system / windows explorer UI. The mouse remains functional but all applications stop responding and ctl - alt - del no longer works. It acts like the system will not release a critical file lock or a low level process might have a have a memory leak. The only thing that changes with the systems is the update to this new versions of avast. They eventually require a hard-off to regain control of the computer. Once the Avast has been disable the issue never returns. I have been recommending Avast for years. If I find out that this app is secretly foisting people into a beta program with issues like theses I will have to consider other options. - A+ Certified System Administrator and Service Repair Tech
