Help, Finding info on the orign of recently discoved files?

by k6lw / May 20, 2006 5:51 PM PDT

I learned a bunch of files, 79 to be exact, apparently were downloaded on to my girlfriends laptop

All were wmv files modified on the same day and within an hour of eachother, and varying in size from abou 7-11MB each.

My girlfriend I learned found these a while ago, and blamed me for the files. She decided to harbor hostile feelings toward me this whole time, while not bringing the issue to me.

I've actually never scene these before. And the time they were modified was too long ago for me to remember what exactly was going on that day.

My question is: Can I extract any more information out of these files so that I can at least attempt to defend myself, or learn more about how they came to be on the computer.

Any help would alleviate some undeserved stress from my life. Thank you.

P2P downloads ?
by linkit / May 20, 2006 7:53 PM PDT

There are settings in P2P file sharing programs that allow for downloading files in the background. Some programs start the downloads automatically upon completion of your keyword search (some people aren't aware of this). If you close the P2P program, the download will stop; but the next time you start the P2P program, the download will resume where it was interupted.

To learn more about the files, tell us the full pathname of where the files are located.

What file extension is on the files (.mp3, .wmv, .ram, other)?

You also can open the folder(s) in which they are located and click View > Details. Right click on the folder column header (where it says Name, Size, Type, Date) to put checkmarks by other details you wish to display.

In reply to: P2P downloads ?

Thanks for the reply. The files are .wmv. We don't have any P2P software. I think a friend of my girlfriend actually downloaded these he comes over to use our internet sometimes.

check your security, too

What firewall, antivirus, antispyware programs are on the computer? I'd run at least one antivirus scan and at least one antispyware scan with two different antispyware programs. Make sure the defiinition files are updated before the scans.

Save and/or print the results of the scan so you can use it to explain what was on the computer (if any of those 79 files were malicious).

What P2P programs are on the computer? Kazaa, Limewire, other?

Any torrent programs installed?

I think a friend of my girlfriend actually downloaded these he comes over to use our internet sometimes. I just don't have any evidence yet. We don't have any P2P software. What are torrent programs? Thanks again.

Metaethic, Sometimes...
by Grif Thomas Forum moderator / May 21, 2006 4:18 AM PDT

..RIGHT click on the file, choose "Properties". When the Properties" window opens, click on the "Summary" tab, then the "Advanced" button. Sometimes, it gives specific information about the file that might help. Sometimes, it doesn't.

In addition, if you know the day when that someone else may have been using the computer, and IF it was fairly recent (within the last 3 weeks for the default setting), and IF you haven't deleted the "History" of the websites that may have been visited in Internet Explorer, you might be able to see the sites that were visited by looking in the folder at this path: C\Documents and Settings\yourusername\Local Settings\History. Open the "History" folder and click on all of the previous days to show the websites that were visited and on which day they were visited.

Hope this helps.

What a torrent program is, and a bit of advice.
by Paul C / May 21, 2006 10:14 PM PDT

A torrent program is a type of P2P software that uses BitTorrent technology to speed up downloads.

http://en.wikipedia.org/wiki/Bittorrent

Now, the advice: Open Windows Explorer (Start/AllPrograms/Accessories/Windows Explorer). Click on the View tab and uncheck the box that reads, "Hide extensions for known file types" under the "Files and Folders" heading. It's a well-known trick of the makicious among us to name a malicious file with two or more file extensions, for example, file.wmv.exe; in this case the file is in fact an executable (.exe) that appears to be a .wmv file unless you let Windows show you all the file extensions (the last extension being the actual type of file).

After you do that, then right-click those files, select "Properties" and see if there are any other extensions there.

Somehow, given the number of files involved, I doubt that there's anything amiss here, but better safe than sorry. You might also tell your girlfriend that her buddy should go do his downloading on his own PC...
