HOW TO MAKE A VIRUS FILE UNDETECTED BY ANTIVIRUS SOFTWARE

Note: As every hacking tutorials is saying, this is only for educational purposes. Don't try to use it on other people.

*Things you will need:
-Displit
-Hex editor
-An infected virus file - Here's an information about it: http://www.file.net/process/servudaemon.exe.html, you can also try other files other than this serVuDaemon.exe.

-An antivirus software(Kaspersky, Clamwin, Avast)

*Steps to be followed:
1. Check with your antivirus program if the file you are using has a virus. To do this, just open your antivirus program. Check if it is up to date. If not, then update it first. Then after the update is done, check if the file has really a virus in it. By using the traditional way of checking. Right click on the file, and then select scan for viruses.

2. Next, split the file with the virus in it. With Dsplit, each file being 10,000 times bigger than the previous or original one.

The syntax for it is:

dsplit.exe STARTBYTE ENDBYTE BYTESIZE TARGET


Sample code is:

dsplit.exe 0 max 10000 servudaemon.exe


3. If you are also using servudaemon.exe, then you can just copy and paste, the code above to your dsplit.exe.

4. If the files are already splitted, scan them using your antivirus program. Some of them will be detected (the one's which contain the virus signitures), some of them will not be detected.


5. Now, lets modify the file that was first detected by the antivirus program. That file will be taken as the range.

6. Scan it using your antivirus program, after the results are written in the antivirus log. Copy the numbers next to the 00000, for example. Just try to watch the video carefully. Because I cannot explain it all.

7. Then you can paste it to your dsplit.exe, following the syntax earlier.
8. Just repeat the entire process, until there is nothing to be detected by the antivirus program.
