Circuits and methods are provided for detecting, identifying and / or removing undesired content. According to one embodiment, a method for virus processing content objects is provided. A type associated with a content object is determined. Based on the type, a subset of instructions is read from a virus signature memory containing intermixed op-codes of a first instruction type associated with primitive instructions and of a second instruction type associated with Content Pattern Recognition (CPR) instructions. Then, instructions of the first instruction type are assigned for execution to a primitive instruction pipe of a virus co-processor and instructions of the second instruction type are assigned for execution to a CPR instruction pipe of the virus co-processor. An instruction is executed by the CPR instruction pipe, including accessing a portion of the content object from a system memory and comparing the portion of the content object against a string associated with the instruction.

Various embodiments of the present invention provide circuits and methods for improved virus processing. As one example, such methods may include providing a system memory, a general purpose processor and a virus co-processor. The methods further include receiving a data segment at the general purpose processor, and storing the data segment to the system memory using virtual addresses.

Circuits and methods are provided for detecting, identifying and / or removing undesired content. According to one embodiment, a method for virus processing is provided. A general purpose processor, communicably coupled to a virus processing hardware accelerator, receives a data segment. The general purpose processor causes the data segment to be stored to a first memory. The general purpose processor directs the virus processing hardware accelerator, communicably coupled to the first memory and to the second memory, to perform a virus scan of the data segment based on one or more virus signatures stored in a second memory. The first memory includes a first virus signature compiled for execution on the general purpose processor. The second memory includes virus signatures, each of which include at least one primitive instruction and at least one Content Pattern Recognition (CPR) instruction stored at contiguous locations, compiled for execution by the virus processing hardware accelerator.

Circuits and methods are provided for detecting, identifying and / or removing undesired content. According to one embodiment, a method for virus co-processing is provided. A general purpose processor stores a data segment to a system memory of the general purpose processor using virtual addresses. A virus processing hardware accelerator coupled to the general purpose processor via an interconnect bus accesses the data segment by performing direct virtual memory addressing of the system memory using the virtual addresses. The virus processing hardware accelerator scans the data segment for viruses by executing pattern comparisons against the data segment. The virus processing hardware accelerator returns a result of the scanning to the general purpose processor by writing the result to the system memory. The general purpose processor may scan the data segment for viruses of a first type in parallel or serially with virus processing hardware accelerator scanning for viruses of a second type.

The invention discloses a virus processing method and device, and belongs to the safety field. The virus processing method comprises the steps of: sending a virus scanning trigger signal based on a virus scanning operation; receiving the virus scanning trigger signal and judging whether at least one of conditions (i) and (ii) below is satisfied: (i) the time interval between the time taken for processing the virus by adopting a first searching and killing mode in the last time and the current time is greater than a preset value, and (ii) a risk condition exists within the time bucket between the time taken for processing the virus by adopting the first searching and killing mode in the last time and the current time; if at least one of the conditions (i) and (ii) is satisfied, calling the first searching and killing mode to process the virus. Through automatic selection of the virus processing mode, which searching and killing mode is most suitable for the current condition of an electronic device can be recognized rapidly and automatically in the virus searching and killing process, and the viral transmission is prevented in time.
