在设置里设置 了【病毒隔离区控制】的密码保护，
于是乎在隔离区里面进行右键删除操作是提示输入密码的，
但无意间， 我按下了键盘上的delete键， 并未要求输入密码， 可以直接删除掉，
不知道我火星了没？
Translation:
The op set up a password to protect the virus chest. When he tries to go to the chest and delete a file, avast asks for a password. But, he accidentally pressed the “delete” key and the op can delete the file in the chest without entering a password.
yes! i got this problem .too!
Indeed another bug!
