Hi, everyone.
I just installed the beta on my Windows Vista Business machine and am greatly satisfied with the memory usage improvement.
It usually consumes between 10 - 20 MB memory (private working set), which is a good thing.
But, I notice something wrong for avast! Web Scanner process.
After I surfed the web for an hour and closed my Opera browser, I opened Task Manager and saw that avast! Web Scanner process consumed 50% CPU usage constantly.
Even though the computer was idle, the CPU usage did not go down.
