Something keeps posting a link on my profile

This is the second time this has happened but there seems to be a bot or something that posts a certain link in my profile.

This is said link please don't go to it for i have no idea what it is : Q http://socialc.am/oanINE

Now i am going to change my password on the site and run a virus scanner to see if there is anything on my PC but i felt like i had to let people know about this.

Edit: i just made some changes in my profile and it seems to be gone now

OK, let me know if the problem repeats. Where was it being posted? The wall, your status, etc.?
