The term disinfection is sometimes mis-used in the anti-malware field. There are several types of viruses, to which this term most appropriately applies are the variety that infect legitimate files. This means your notepad.exe has a virus appended on to it. Some AVs treat "disinfection" the same as quarantining the file. The standard definition of disinfecting a virus would be to locate the virus code inside the legitimate file and remove/alter the harmful code which allows the executable to function as it normally would. Clamav, and by extension Clamwin, detect a minority of file infecting viruses, but do not have a mechanism to remove the viral code. It is worth noting that in the instance that viral code is found it is usually safer and better to restore the original copy of the executable than attempting to repair it. Repairing is sometimes an error prone and difficult process than discovering the initial detection and does not always work for the AV's that implement true disinfection. |

Repair increases the size/complexity of the code of antivirus software. That's one of the reasons for the bloated software produced by the large antivirus companies, and it's getting harder to do a really complete repair--because of today's multiple malware payloads. Perhaps people/users will be more careful if they have to clean up the mess for which they are often responsible in the first place! Regards, |
