I'm sorry if my explanation is a little confusing, I had a long night and my grammar is terrible this morning. I'll answer any questions to the best of my ability.

I've been having a problem where pornographic videos are being downloaded while no one is using the computer. It's been happening for awhile now, I brushed it off though because when it had started I had Windows Vista installed as my OS which I knew I was going to upgrade with a clean install of Windows 7 soon. Now I have had Windows 7 for two weeks now and the same problem arose again on Tuesday (Nov 17). I've become frustrated with this after trying various methods to identify the problem and remove it myself, from having quite a bit of experience with Computers and Computer Security myself, but nothing came up. I've ran scans with AVG Free, looked through file directories, looked at the internet history of all Web Browsers etc. No Dice, everything looks normal.

The material being downloaded is always in .mpg format and is downloaded to this directory: C:\Users\Alec\Documents\Downloads

System Specifications:
Operating System: Windows 7 Home Premium 32-bit (6.1, Build 7600) (7600.win7_rtm.090713-1255)
BIOS: )Phoenix - Award WorkstationBIOS v6.00PG
Processor: AMD Phenom™ 9600 Quad-Core Processor (4 CPUs), ~2.3GHz
Memory: 4096MB RAM
Available OS Memory: 2942MB RAM

Main Web Browser: Google Chrome (3.0.195.33)
Secondary Web Browser: Internet Explorer (8.0.7600.16385)

I should also mention that my Stepbrother uses this computer, however, he claims that the files were not from him and from what the history shows he telling the truth. (He wouldn't know how to delete the internet history, he barley can make frozen dinners without asking me for help.)

I'm not going anywhere today and I'll be watching this thread closely, so please, ask any and all questions you may have.

Lets take a look with Malwarebytes

Please download Malwarebytes' Anti-Malware from here:
Malwarebytes
Please rename the file BEFORE downloading to zztoy.exe instead of mbam-setup.exe

MBAM may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you. Temporarily disable such programs or permit them to allow the changes.

Double Click zztoy.exe to install the application.
* Make sure a checkmark is placed next to Update Malwarebytes' Anti-Malware and Launch Malwarebytes' Anti-Malware, then click Finish.
* If an update is found, it will download and install the latest version.
* Once the program has loaded, select "Perform Full Scan", then click Scan.
* The scan may take some time to finish,so please be patient.
* When the scan is complete, click OK, then Show Results to view the results.
* Make sure that everything is checked, and click Remove Selected.
* When disinfection is completed, a log will open in Notepad and you may be prompted to Restart.(See Extra Note)
* The log is automatically saved by MBAM and can be viewed by clicking the Logs tab in MBAM.
* Copy&Paste the entire MBAM report (even if it does not find anything) in your next reply

Extra Note:
If MBAM encounters a file that is difficult to remove,you will be presented with 1 of 2 prompts,click OK to either and let MBAM proceed with the disinfection process, if asked to restart the computer, please do so immediately.


If Malwarebytes won't install or run

Some types of malware will disable MBAM and other security tools. If MBAM will not install, try renaming it. Right-click on the mbam-setup.exe file and change the .exe extension to .bat, .com, .pif, or .scr and then double-click on it to run.

If after installation, MBAM will not run, open the Malwarebytes' Anti-Malware folder in Program Files, right-click on mbam.exe and change the .exe as noted above. Then double-click on it to run.

Ok, lets scan with SAS:

Please run ATF and SAS:

I do not think that this is malware related. Are you sure that it is not a possibility that your stepbrother could be doing it?

I'm sure, the creation date is sometimes at a time where no one is home.

If by on and active you mean Windows is booted up, however system is idle although some services (Mozilla Thunderbird, uTorrent, etc.) are still running, then yes.

From using uTorrent from far before this problem had existed, I can confidently say that it is not the source of it.
