Why didn't the killer go to work for antivirus manufacturers such as 360?

What you say is not necessarily a real master. If he is a master, there will be a very powerful manufacturer who will pay a high price for him. For example, Kaspersky's team has many virus experts.

2, the master of free killing is not necessarily a master of c++ or c# or other programming, because as a master, don't just do free killing and do nothing else. If you can write the source code, the manufacturer will definitely like it.

3, there is no stepping stone to enter the door, such as undergraduate education, how many years of employment.

If you know the experience of Li Jun, the author of Panda Burning Incense, you will know that if he goes to work in 360 or Rising, he can only be a virus tester. In addition, you can look at Kingsoft Internet Security's anti-virus engineer recruitment brochure at that time. What I said above is only a small part. I hope my answer is helpful to you.
