不好意思,又来添垃圾贴,嘿嘿,SourceFormatX 万能源代码格式化工具 2.5.6.1
也是比较早的东东了,落后了,应该不会被追讨了吧.但是因为这个软件也有可恶的地方.by zzhzihui@163.net
SourceFormatX 万能源代码格式化工具 2.5.6.1
1.>ANTI-CRACK,导致系统死锁
很讨厌，判断文件大小，报错，说是可能感染病毒,若强行改动,则不停加载explorer.exe,导致系统满载,死机.
这里有一处:
0055F10A 50 PUSH EAX
0055F10B E8 D477EAFF CALL <JMP.&kernel32.GetFileSize>;从文件大小判断
0055F110 3D A8421200 CMP EAX,1242A8

该程序会搜索有关ollydbg,filemon....的窗口标题或窗口类,有则关闭,可以在脱壳文件里搜索ollydbg,trw,sice.....改掉,
但是有些是加密存放的,无法搜索到,例如:

00556144 50 PUSH EAX
00556145 E8 620DEBFF CALL <JMP.&user32.FindWindowA> ;ollydbg

00556153 E8 BC0EEBFF CALL <JMP.&user32.GetWindowThreadProcess>
