Repairing files
The "Repair ..." command will try to return the files to their original state. When you select it, a dialog allowing to repair the file would appear. If the file being corrected is an OLE document, the user is enabled to preset some parameters.
Through the radio button "Delete only virus macros from the document" it is possible to preset that only the macros, in which a virus has been found, should be removed from the document. The other macros will remain untouched.
The radio button "Delete all macros from document" will cause that all the macros will be removed from the OLE document, whether they contain a virus or not.
The default setting is to remove only those macros that contain a virus. Checking the box "Force delete all macros if virus not recognized exactly" you will set to the program that if the virus has not been recognized with full exactness (in the case of some macroviruses the detection is very difficult), all the macros are to be removed from the document.
If a file which does not contain an OLE document is to be corrected, AVAST32 will try to correct the file by using the method based on the integrity checking. The truth is that AVAST32 maintains its internal database of files, into which it records important information on the status of individual files, and with the help of checksums, also on their contents. With using this information AVAST32 will try to repair the file selected. It is possible to repair up to ninety-five per cent of the files infected. AVAST32 is able to determine at one hundred per cent precision, whether the file has been repaired or not.
It follows from the previous text that if you want to repair the files successfully, you will need a periodically updated database of the files on your disks. This database must be maintained, in other words, it is necessary to perform integrity checking from time to time, and to record authorized changes in the files into the internal database of the "Accept" command.
The algorithms used for the repairing of the files in AVAST32 are exclusively able for the repairing of the files infected by a virus. Thus they cannot be used for the renewal of rewritten or edited files. The presetting of the controls of the dialog is displayed for the files that do not contain any OLE documents.
By pressing the "Repair" button the file repairing process itself will be started-up.
By pressing the "Repair All" button the repairing process of all selected file will start.
Using the "Cancel" button you will close the dialog, and the selected files will not be manipulated.
