Hey guys, just opened up a link on steam from someone and stupidly opened and ran the file which was a .scr.

From a preliminary search it seems that I may have installed a Trojan, so any help would be appreciated.

 

Running a Windows 7, with the only security software being Microsoft Security Essentials (which a scan didn't turn up anything awry).

 

Many thanks for any help!

 

 

Edit: here's the logs of the security check I just ran

 Results of screen317's Security Check version 0.99.91

A quick look on the web found this: Rogue .SCR File Links Circulating in Steam Chat | Malwarebytes Unpacked

 

We mentioned rogue .scr files being passed around the Steam network (specifically, in chat) in September, and they seem to be making a bit of a comeback.

We’ve noticed a number of posts on both Steam forums [1], [2], [3], [4] and elsewhere talking about messages sending potential victims to bit.ly URLs. Typically, the scammers are sending fake Steam Marketplace trade offers, and the supposed “picture” of whatever virtual item they’re offering up is actually an .scr file which will run should the victim double click and execute it.

steamscr-300x107.jpg

The Bit.ly URL displayed in the Tumblr post linked above currently has 2,000+ clicks – and that’s just one random example.

There’s sure to be a lot more clicking going on elsewhere. Users of Malwarebytes Anti-Malware will find we detect the file offered up as Trojan.Inject (VirusTotal 33 / 54, Malwr analysis).

A search for .scr files on the Steam Community forums reveals quite a lot of fresh “I opened this .scr file and now I’m having a bad hair day” posts in the last few days, so please ensure you avoid any and all links sent via Steam chat which lead to .scr files.

Just because the name of the file says “IMG” at the start doesn’t mean it’s actually an image file. The extension in these cases is the giveaway, and users of Steam should ensure they’re not being set up for a harsh lesson in digital shenanigans.

 

So, I think after you have rerun AdwCleaner and chosen Clean to remove what it found, you should run two more scans.

 

Download Malwarebytes' Anti-Malware from Here

Double-click mbam-setup-2.X.X.XXXX.exe to install the application (X's are the current version number).

  • Make sure a checkmark is placed next to Launch Malwarebytes' Anti-Malware, then click Finish.
  • Once MBAM opens, when it says Your databases are out of date, click the Fix Now button.
  • Click the Settings tab at the top, and then in the left column, select Detections and Protections, and if not already checked place a checkmark in the selection box for Scan for rootkits.
  • Click the Scan tab at the top of the program window, select Threat Scan and click the Scan Now button.
  • If you receive a message that updates are available, click the Update Now button (the update will be downloaded, installed, and the scan will start).
  • The scan may take some time to finish,so please be patient.
  • If potential threats are detected, ensure that Quarantine is selected as the Action for all the listed items, and click the Apply Actions button.
  • While still on the Scan tab, click the link for View detailed log, and in the window that opens click the Export button, select Text file (*.txt), and save the log to your Desktop.
  • The log is automatically saved by MBAM and can also be viewed by clicking the History tab and then selecting Application Logs.

POST THE LOG FOR REVIEW.

 

  • Hold down Control and click on this link to open ESET OnlineScan in a new window.
  • Click the esetonlinebtn.png button.
  • For alternate browsers only: (Microsoft Internet Explorer users can skip these steps)
  • Click on esetsmartinstaller_enu.exe to download the ESET Smart Installer. Save it to your desktop.
  • Double click on the esetsmartinstaller_enu.png icon on your desktop.
  • Check "YES, I accept the Terms of Use."
  • Click the Start button.
  • Accept any security warnings from your browser.
  • Under scan settings, check "Scan Archives" and "Remove found threats"
  • Click Advanced settings and select the following:
  • Scan potentially unwanted applications
  • Scan for potentially unsafe applications
  • Enable Anti-Stealth technology
  • ESET will then download updates for itself, install itself, and begin scanning your computer. Please be patient as this can take some time.
  • When the scan completes, click List Threats
  • Click Export, and save the file to your desktop using a unique name, such as ESETScan. Include the contents of this report in your next reply.
  • Click the Back button.
  • Click the Finish button.
  • NOTE:Sometimes if ESET finds no infections it will not create a log.

I have not cleaned it yet, but will do so now. 

 

I am not noticing anything malicious or acting funny currently but to be cautious am avoiding typing any credit information or the like.

MBAM found and removed one item that could of been what you downloaded instead of the image file....Spyware.OnlineGames, C:\Users\Brian\Downloads\screenshot.scr, Quarantined, [e394baa484f880b681ce40206e92ee12]

 

Download Junkware Removal Tool to your desktop.

  • Shut down your protection software now to avoid potential conflicts.
  • Run the tool by double-clicking it. If you are using Windows Vista, 7, or 8; instead of double-clicking, right-mouse click JRT.exe and select "Run as Administrator".
  • The tool will open and start scanning your system.
  • Please be patient as this can take a while to complete depending on your system's specifications.
  • On completion, a log (JRT.txt) is saved to your desktop and will automatically open.
  • Post the contents of JRT.txt into your next message.

Use CCleaner to remove Temporary files, program caches, cookies, logs, etc. Use the Default settings. No need to use the

Registry Cleaning Tool...risky. Pay close attention while installing and UNcheck offers of toolbars.

You may see Google Tool Bar being offered.

CCleaner - PC Optimization and Cleaning - Free Download

 

Reset Google Chrome:

Google Chrome gives you the option to reset your browser settings in one easy click. In some cases, programs that you install can change your Chrome settings without your knowledge. You may see additional extensions and toolbars or a different search engine. Resetting your browser settings will reset the unwanted changes caused by installing other programs. However, your saved bookmarks and passwords will not be cleared or changed.

  1. In the top-right corner of the browser window, click the Chrome menu
  2. Select Settings.
  3. At the bottom, click Show advanced settings.
  4. Under the section "Reset settings,” click Reset settings.
  5. In the dialog that appears, click Reset.

I think so. Is the computer performing okay? If so, happy surfin !

 

You can use CCleaner as often as you like and to see what is starting up in Windows, browsers and Tasks by clicking on Tools and choosing Startups.

CCleaner will be one program unnecessary to start when booting. You may find others that when disabled will a faster boot and decrease memory usage.

Google updates don't need to be in startup or Tasks. Check it out and if you have any questions....just ask.

The computer is performing excellently!

 

Thanks for re-introducing me to the old friend that is CCleaner, and many thanks to everyone for the help!
