How do you create an antivirus software by using c language?
This is a basic antivirus code that i made and use on my computer (besides Norton) @echo off title Antivirus echo Created By Your Name pause IF EXIST virus.bat delete virus.bat echo Antivirus Has Secured Your Computer IF NOT EXIST virus.bat echo Computer Is Already Secure end This program follows a fairly simple algorithm. First it finds certain strings of code in a file that determines if it is a virus. If it is, then it deletes it and creates a message in the window saying your computer is secure. If no virus exists, the program says your computer is already secure and then ends its function. If you want to make this program never stop scanning, replace the end at the end of the code, and put loop in its place. If you did this, type exit at the end of the code. Loop makes the program constantly scan without ending ever. This is not the strongest antivirus I've made, but it is still effective. This program can only detect viruses and nothing else. If your computer has a trojan on it or something else, this program can't detect it. Highlight the code, click Copy, open up Notepad, right click, and select Paste, and then Save As Antivirus.bat and then send it to your Desktop.
