There is an foreign application on my account
There is a foreign application on my account, that was bought not from my account. I really don't get it. It pops up in the mac app store that it's ready to be updated but it was bought from an email adress I don't know. I'm attaching a photo. anyway, how do I get rid of it? obviously I don't recognize the email adress and i don't know the password but it pops up in my account When i log in, so seriously no idea what to do.
MacBook Pro (15-inch Early 2011), Mac OS X (10.7.3)
