We often process files originating from different sources. To prevent computers from being affected by computer viruses, we should use anti-virus programs. Computer viruses can duplicate themselves on computers. They can propagate through networks or by duplicating and sharing files and software, etc. They can damage computer systems, occupy storage space, consume CPU time, etc. For seriously infected computer systems, the computers may also cease operation.

Different anti-virus programs will detect and handle computer viruses in different ways. Some focus on a series of unique codes, the virus codes, found in the computer virus. Before we save or access a file, the anti-virus program scans the file and checks if there are any virus codes embedded in the file. If a computer virus is found, the anti-virus program will report with a warning signal, and then the user can determine how to handle the infected file.

As new computer viruses emerge all the time, as well as using anti-virus programs to scan the files, we need to frequently update the anti-virus program with the virus signature update file so that we can minimize the opportunity for virus
