My mac screen has a blue line?

MAC possible trojan/virus - amazon order, pink line on screen and more.?

• I downloaded a torrent/sharing application, but I did not download any torrents (because they wouldn't) About a day after, a pink line appeared on the screen, and won't go away. Today, a parcel arrived from amazon - It had been paid for by my card and sent to my address. I did not order this item! (i'm sending it back) - The item may have been in my viewing history/recommendations, but I'm not too sure. I paid my ebay seller fees (a one-off debit payment) but did not receive a conformation email from ebay (I don't know if I was meant to, this is the first time paying for seller fees) Please Help! thanks

• Answer:

  It would help if you tell us what the torrent app. you installed was, but a quick look on a number of Mac security sites show that it's more than likely you've installed some MalWare. Get onto a clean machine and get your passwords for Amazon, banking, any and all other online services, changed asap. Remember, Macs have the KeyChain store (in Utilities) and you'll have entered the master password when you installed the malware so the malware has access to every piece of information in your keychain. Get the Mac off the internet (disconnect wireless and wired networks) and don't reconnect it until you've scanned and cleaned it with whatever internet security package you're using. Your internet security package should have found the malware before you got as far as installing it. Which one are you using and when did it last update?
