    So, this "lostboy.exe" mediafire link has been spreading through 4chan's videogames board like wildfire, and a few days later, the admin posted a message confirming it as a Backdoor RAT file:


    The original poster of the link claimed that the file contained a scary "slenderman-like" video game, and also posted believable screencaps from the game, contributing to a bunch of people downloading it.

    A while later, someone claiming to be the OP (it's an anonymous imageboard, so you can never know) started posting screencaps of him spying on people through their webcam, manipulating their computers, and most noticeably uploading private information(bank accounts, facebook accounts, ebay accounts) pertaining to the infected users on Pastebin and sharing it all.

    Many questions are currently being asked about this file on 4chan, but you are guaranteed to find no plausible argument about it, as most of them joke around and clearly exaggerate about the case, while others post more rational arguments that are countered by other rational arguments and vice-versa to infinity until a black hol... :zzz
    Well, in other words: 4chan is not an accountable source of information

    As for myself, I ended up downloading it, running it, and later noticing the apparent mistake I've done. I forbid the 2 processes related to the .exe from running, deleted some folders and registries associated with it, and ran a hidden objects/rootkit scan on Avira, which didn't pick up much.

    Finally, my question is: How do I know if I am safe from this RAT thing?

    Welcome to the Malware Removal Forum.

    Please read ALL of this message including the notes before doing anything.

    Pleases follow the instructions in the below link:

    READ & RUN ME FIRST. Malware Removal Guide

    and attach the requested logs when you finish these instructions.
    • **** If something does not run, write down the info to explain to us later but keep on going. ****
    • Do not assume that because one step does not work that they all will not. MGtools will frequently run even when all other tools will not.

    • After completing the READ & RUN ME and attaching your logs, make sure that you tell us what problems still remain ( if any still do )!
    Helpful Notes:

    1. If you run into problems trying to run the READ & RUN ME or any of the scans in normal boot mode, you can run the steps in safe boot mode but make sure you tell us what you did later when you post logs. See the below if you do not know how to boot in safe mode:
    2. If you have problems downloading on the problem PC, download the tools and the manual updates for SUPERAntiSpyware and Malwarebytes ( links are given in the READ & RUN ME) onto another PC and then burn to a CD. Then copy them to the problem PC. You will have to skip getting updates if (and only if) your internet connection does not work. Yes you could use a flash drive too but flash drives are writeable and infections can spread to them.
    3. If you cannot seem to login to an infected user account, try using a different user account (if you have one) in either normal or safe boot mode and running only SUPERAntiSpyware and Malwarebytes while logged into this other user account. Then reboot and see if you can log into the problem user account. If you can then run SUPERAntiSpyware, Malwarebytes, ComboFix and MGtools on the infected account as requested in the instructions.
    4. To avoid additional delay in getting a response, it is strongly advised that after completing the READ & RUN ME you also read this sticky:
    Any additional post is a bump which will add more delay. Once you attach the logs, your thread will be in the work queue and as stated our system works the oldest threads FIRST.
