In Terminal, type diskutil info /Volumes/volume_name, where volume_name is the name of the NTFS volume. From the output, copy the Volume UUID value to the clipboard.
Back up /etc/fstab if you have it; it shouldnt be there in a default install.
Type sudo nano /etc/fstab.
In the editor, type UUID=, then paste the UUID number you copied from the clipboard. Type a Space, then type none ntfs rw. The final line should look like this: UUID=123-456-789 none ntfs rw, where 123-456-789 is the UUID you copied in the first step.
Repeat the above steps for any other NTFS drives/partitions you have.
Save the file and quit nano (Control-X, Y, Enter), then restart your system.

I removed it because Windows kept asking to check the system every time OSX made a change in its partition...

Well, well, well... NTFS in OSX is just rubbish. I just lost some files!!!! Damn you OSX with NTFS support.
