Thanks dexterrules4 for your reply. Now I understand and will go back watching.

dexterrules4,

Some of us belong to the Wipe and Clean Club, and others belong to the Good Riddance Club.
I belong to the latter. However, even when we try our best, when dealing with an infected system, cannot offer any guarantees.
