    So far, Avira Free and SUPERAntiSpyware Pro haven't picked up on anything except one instance of the very annoying but not that dangerous MyWebSearch. However, here's what this system's doing:


    Vista 32-bit Home Premium in an Admin account

    If you try to download anything in Internet Explorer or Safari (haven't bothered trying any other browser yet), as soon as you download a file, the file is gone. I cannot reproduce this auto-delete new file behavior in anything else (eg. copying files to system). I tried creating a new user account, but the problem persists in both browsers.

    :confused

    Welcome to MajorGeeks, pancakes

    My research indicates that you're probably infected with a TrojanDownloader variant.

    NOTE: This malware is highly dangerous, can download and execute other malicious programs, and opens a huge security hole on your computer.

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

    Please follow the instructions in the below link:

    READ & RUN ME FIRST. Malware Removal Guide


    and then attach the requested logs to your next reply 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.
