Problems solved by technology

Computer viruses are not only destructive in themselves, but more harmful are contagious. Once the virus is replicated or mutated, the speed is hard to prevent. The loss and destruction of computer resources will not only cause a huge waste of resources and wealth, Moreover, it may cause social disasters. With the development of the information society, the threat of computer viruses is becoming more and more serious, and the task of anti-virus is becoming more and more difficult.
[0004] In view of computer security problems caused by computer viruses, almost every computer user will install anti-virus software now, but the current problem is that a computer can often only install one anti-virus software and use one virus database. Obviously, A single virus database is always powerless for the ever-changing viruses. In order to improve the virus detection an

Embodiment 1

[0056] Embodiment one, see figure 1 , the antivirus method provided by the embodiment of the present invention, comprises the following steps:

[0057]Step 101: Detect whether there is a virus scanning command, if there is the virus scanning command, go to step 102, otherwise continue to detect.

[0058] Step 102: according to the virus scanning command, invoke the main antivirus engine of at least two antivirus engines to scan and kill the object required to be scanned by the virus scanning command.

[0059] Step 103: When the virus detected by the main antivirus engine is an unknown virus, invoke the auxiliary antivirus engine of the at least two antivirus engines to scan and kill at least one object required to be scanned by the virus scanning command.

[0060] In the embodiment of the present invention, the main anti-virus engine is the anti-virus engine with the highest detection and killing rate among the many local anti-virus engines, and all engines except the main an...

Embodiment 2

[0067] Embodiment 2. In practical applications, different methods may be used to scan the object required to be scanned according to the suspiciousness of the object required to be scanned by the virus scanning command. See figure 2 , the method specifically includes:

[0068] Step 201: Detect whether there is a virus scanning command, if so, go to step 202, otherwise go back to step 201 to continue detection.

[0069] Step 202: Determine whether the scanned object required by the virus scanning command has a record of being infected by a virus, if not, go to step 204; otherwise, go to step 203.

[0070] Step 203: Determine whether the object is a suspicious object, if not, go to step 204; if yes, go to step 205.

[0071] The suspicious object refers to an object whose virus infection rate is higher than a preset threshold.

[0072] Wherein, in step 202, it is judged whether the object that the virus scanning command requires to scan is a possible object is specifically:

...

Embodiment 3

[0083] Embodiment three, see image 3 , the antivirus method that realizes many antivirus engines that this embodiment provides comprises:

[0084] Step 301: Detect whether there is a virus scanning command. If there is the virus scanning command, go to step 302; otherwise, return to step 301 to continue detection.

[0085] Step 302: Determine whether the object scanned by the virus scanning command has a virus infection record, if not, go to step 304; otherwise, go to step 303.

[0086] Step 303: Determine whether the object is a suspicious object, if not, go to step 304; if yes, go to step 305.

[0087] Step 304: The master and assistant assist in scanning and killing the object required to be scanned, and proceed to step 306.

[0088] Step 305: Invoke the at least two antivirus engines in turn to detect and kill the suspicious objects, and proceed to step 306.

[0089] Step 306: Determine whether a virus is found, if not, go to step 301; otherwise go to step 307.

Abstract

The invention discloses a virus killing method and a virus killing system with multiple antivirus engines. The method comprises the following steps: acquiring a virus scanning command; calling a mainantivirus engine of at least two antivirus engines to search and kill an object which the virus scanning command requires to scan; calling an auxiliary antivirus engine in at least two antivirus engines to search and kill the object which the virus scanning command requires to scan, wherein the virus killing rate of the main antivirus engine is more than that of the auxiliary antivirus engine, andthe auxiliary antivirus engine can be other antivirus engines except the main antivirus engine of at least two antivirus engines. Therefore, the method realizes high speed multi-antivirus engines searching and killing on the scanning object basing on the fact that the success ratio of searching and killing is guaranteed.

Description

technical field [0001] The invention relates to the field of computer security, in particular to a method and system for killing viruses with multiple killing engines. Background technique [0002] With the continuous development of computer technology, now, whether in daily life or work, computers have become an indispensable partner for people, bringing a lot of convenience to people's work and life, but among them There is a discordant factor, and that is the computer virus. [0003] A computer virus refers to a set of computer instructions or program codes compiled or inserted into computer programs that destroy computer functions or data, affect computer use, and are capable of self-replication. Computer viruses are not only destructive in themselves, but more harmful are contagious. Once the virus is replicated or mutated, the speed is hard to prevent. The loss and destruction of computer resources will not only cause a huge waste of resources and wealth, Moreover, i...
