Abstract
The detection and removal of viruses from macros is disclosed. A macro virus detection module includes a macro locating and decoding module, a macro virus scanning module, a macro treating module, a file treating module, and a virus information module. The macro locating and decoding module determines whether a targeted file includes a macro, and, where a macro is found, locates and decodes it to produce a decoded macro. The macro virus scanning module accesses the decoded macro and scans it to determine whether it includes any viruses. Unknown macro viruses are detected by the macro virus scanning module by obtaining comparison data that includes sets of instruction identifiers from the virus information module and determining whether the decoded macro includes a combination of suspect instructions which correspond to instruction identifiers. The macro treating module locates suspect instructions in the decoded macro using the comparison data and removes the suspect instructions to produce a treated macro. The file correcting module accesses a targeted file with an infected macro and replaces the infected macro with the treated macro produced by the macro treating module.
