I developed a website using wordpress. In the log file (which shows the ip addresses and the pages which have been accessed) I got some unknown addresses which have been accessed from my site although they are not actually exist. These addresses have been accessed from many parts of the world. Some example addresses are:
xxx/c3e/bfv-software-to-monitor-computer-activity-remotely-free xxx/rl8/bbx/7-hack-app-that-allow-you-to-view-wifes-or-girlfriends-facebook-secretly.html xxx/c3e/bfv-keylogger-for-windows-phone
here xxx represents my actual web address. Do you have any idea about these address, their purpose and how to prevent these?
