Hello. I want to get the skills to máster the computer machine architechture. Crackers are always able to decode any algorithm. I want to have skills to join an antivirus company reversing malware, because that is my goal. Such programmer are always in the top. In summary I want to be able to use all the power of my computer. I am focusing only in reverse engineer to keep it short and clear.

The RE community have this annual challenge for malware analysis, you can look up "Flare-On" and try practising with their previous contest since 2014. They have mocked files in PE, ELF, XLS (macro) and many more for you to reverse.

You will need to know digital forensics, and of course, Assembly language.
Good luck with that.

You can start from here.

Thanks for your help. The links of ollydbg are broken I can not Enter in the communities. I need all support do you know other communities?? Fasm is ok too because the same applies for cracking software. I have a dude flare on contains a malware sample?? I planned malware antivirus work for later I am know interested in reverse engineer. Just a caution because I have little experience reversing and less if the sample will be risky. Do you have books about reverse engineer for free?? They will be Welcomed.

Yes, the sample in the Flare-On would trigger Windows Defender. They advise you to try reverse them on isolated machine or virtual machine (VM).

Isn't Olly 32 bit only?..

Fastest way is to use Cheat Engine

In the past there were lots of "crackme" exe files around. Sometimes even a series with increasing difficulty. They were created especially to train your cracking skills.
