Enhorabuena ricardo for your tutorials. I've a problem with a crackme that i found in the net, it has a debugger detection but i cant crack it. the crackme is done with vb6. my question is : how can disable the antidbg routine? thanx

IN nt/2000 and XP is more easy, in 98 is more difficult,what SO have you.

i have win98, i cant find isdebuggerpresent in kernel32. in command line i wrote bp isdebuggerpresent but didn't work. Please ricardo if you have some new tutorial about this tell me. i've seen your tutorials "toda la teoria comprimida" zip file but doesn't help me about that. thankx

no set breakpoint. examine targets iat for isdebuggerpresent and overwrite this part of the iat with your own code that will simply return false. then no matter how many times it's called, it will never trigger.

Thankx, i did't by nopping isdebuggerpresent routine in kernel32.dll, and xor eax,eax befor ret. it works, thankx for your help. I have an other question, how can i set a breakpoint on hmemcpy in win98
