The invention discloses an initiative
intercept method and an initiative intercept device for a malicious program and
client end equipment. The initiative intercept device for the malicious program comprises an intercept object selection unit, an intercept information setting unit, an intercept point monitoring unit and an intercept
execution unit, wherein the intercept object selection unit is suitable for selecting an intercept object needs to be intercepted according to an access mode of a
client end to key input data; the intercept information setting unit is suitable for arranging intercept execution information aiming at the intercept object in an
application layer and / or a drive layer; the intercept point monitoring unit is suitable for acquiring information of a key input data accessing program when the key input data is monitored; the intercept
execution unit is suitable for judging whether the program is safe according to the information of the program, if so, the program is allowed to call the key input data, if not, the program is intercepted, wherein the intercept point monitoring unit is suitable for judging whether the monitored key input data is
data needs to be protected before the information of the key input data assessing program is acquired, if so, the information of the key data assessing program is acquired, and if not, the operation is finished.
