Step 1: PEID shell check: ASPack 2.12-> Alexey Solodovnikov. To save time, you can directly remove it from the shelling machine and use PEID shell check: Microsoft Visual Basic 5.0/6.0. The program is written in vband the shell file is saved as a multi-function password cracking software.
Run the program. In the registration window that appears, enter a false code and prompt: do not perform any operation. Restart the software to check whether the registration is successful!
