Remote Access Trojan.
It's worse then a virus, trojan, and worm. It's called the Black Orifice created by the Cult of the Dead Cow. You can find out if you have this by searching for ".RAT" using advanced search options on your computer. If you have it, your screwed because now you don't have your computer...your borrowing it.
Say hi to the hacker that's watching you that gave you the RAT.

Relationship Assuring Text. RAT's are SMS messages sent to convey approval of or delight in a previous social encounter with an individual of undefined relationship status with the sender. A RAT is most commonly employed after a first date where one or both parties are unsure about the perceived success of the other party. Such dates are often seen as "Awkward dates" by third parties. An exchange of RAT's sent the evening after a first date almost ensure a second date, effectively breaking the ice for more casual conversation.

The effectiveness of "Morning RAT's" (RAT's sent the morning after a first date) are hotly debated because they are believed by some to close the deal, but can also be seen as a red flag.
