Is it really possible to do a "simple" anti-virus code, I suppose you'd need a big list of viruses, where they install too, what their file name is, then read from this list, scan directory if it exists, delete.... doesn't sound so simple really..

Do you know how to monitor processes and file access yet? If not, you will have a hard time doing anything real time. In that case, you are limited to scanning files for database matches.

thanks to all
i think scannig a directory is best suited for me:sad:
but in that case please let me know how to do that using C?
thanks in advance

It will depend somewhat on the operating system you are using, as well as the libraries you have available. You need to get a list of all the files in a folder, and then open them and read their contents, checking for certain strings of characters. Are you familiar with file access in C?

yup.. me familiar with file access in C
"You need to get a list of all the files in a folder, and then open them and read their contents, checking for certain strings of characters." how!i m distressed:crying:

C does not have the concept of a folder. You will need to learn the Windows API to get the list of files in a given folder.

Once you have a list of files, you can open each one. You will have to use string manipulation routines to (attempt to) locate virus substrings within the string.
