Delete system files
Hello everyone! I wanna write a C++ code to delete a file. I use remove() finction. But it CANNOT delete any file I want. For example, I wanna delete a file from C:\\Windows directory, but that function does not do that.
P.S. I don't wanna make any virus. Just it's interesting

Yea doing that is virus activity. So whether you truly want to or not, is meaningless. Unless you plan on frying your own windows partition you are writing a virus for illegal use.
DeleteFile function:
http://msdn.microsoft.com/en-us/library/aa363915(VS.85).aspx
DeleteFile("\\\\.\\C:\\Windows\\file.exe");
\\.\ at the begining of file path sometimes allows to delete file even if the file is used by another program.

@ Seraphimsan: That's kind of pessamistic. I'd think that if the OP were capable of writing a malicious program they would know how to use a function like remove().
Now if they got into specifics like loading their program as a registered service, forging the security token on a thread\process, Hooking the API to overwrite the Kernel32.dll IAT. Now those are some questions we should worry about. Until then there's no need to think the worst of people ;).

@Seraphimsan, you were right! I plan on frying my own windows partition. How did you guess???

You're not helping by being sarcastic.
@Seraphimsan,
I don't think OP was seriously saying he wanted to delete a file from C:\Windows; I think that was probably just an example.
I tried writing a program in assembly that would be able to copy it's code into a binary file on UNIX. I had finished writing the function to copy the code
Afterthought: it wasn't a virus. I merely wanted to try self-replication. It wouldn't have worked as a 'virus' anyway, because I was passing the input and output files as argv[0] and argv[1] respectively. I also tried code mutation (i.e. a program that could edit itself) but it didn't work either. I tried having markers in the text section (dd) but the assembler put them in .data :(
