Got this a couple of times. Once when I was going on a forum and twice when I was running malwarebytes.

What is it? o.O

It's a JS_PSYME.ASJ Downloader trojan.

Description:

A JavaScript may be written with malicious intent. Script malware makes use of Microsoft's Windows Scripting Host (WSH). WSH is a Windows administration tool that makes objects and services available for various scripts and provides a set of guidelines within which the script is executed. It allows remote malicious users to run scripts from the Windows desktop, Windows Explorer, and Windows command prompt.

WSH cannot distinguish between malicious and non-malicious script. Double-clicking on a script malware file will cause the malware to run its main action and payload, thus infecting the system.

Did MBam remove it?

Hi, I feel we should run these two scans as they list removal of this.

Before we start fixing anything you should print out these instructions or copy them to a NotePad file so they will be accessible. Some steps will require you to disconnect from the Internet or use Safe Mode and you will not have access to this page.

Please download DrWeb-CureIt and save it to your desktop. DO NOT perform a scan yet.

Reboot your computer in "Safe Mode" using the F8 method. To do this, restart your computer and after hearing your computer beep once during startup (but before the Windows icon appears) press the F8 key repeatedly. A menu will appear with several options. Use the arrow keys to navigate and select the option to run Windows in "Safe Mode".

Scan with Dr.Web CureIt as follows:
  • Double-click on launch.exe to open the program and click Start. (There is no need to update if you just downloaded the most current version
  • Read the Virus check by DrWeb scanner prompt and click Ok where asked to Start scan now? Allow the setup.exe to load if asked by any of your security programs.
  • The Express scan will automatically begin.
    (This is a short scan of files currently running in memory, boot sectors, and targeted folders).
  • If prompted to dowload the Full version Free Trial, ignore and click the X to close the window.
  • If an infected object is found, you will be prompted to move anything that cannot be cured. Click Yes to All.
  • When complete, click Select All, then choose Cure > Move incurable.
    (This will move any detected files to the C:\Documents and Settings\userprofile\DoctorWeb\Quarantine folder if they can't be cured)
  • Now put a check next to Complete scan to scan all local disks and removable media.
  • In the top menu, click Settings > Change settings, and UNcheck "Heuristic analysis" under the "Scanning" tab, then click Ok.
  • Back at the main window, click the green arrow "Start Scanning" button on the right under the Dr.Web logo.
  • When the scan is complete, a message will be displayed at the bottom indicating if any viruses were found.
  • Click "Yes to all" if asked to cure or move the file(s) and select "Move incurable".
  • In the top menu, click file and choose save report list.
  • Save the DrWeb.csv report to your desktop.
  • Exit Dr.Web Cureit when done.
  • Important! Reboot your computer because it could be possible that files in use will be moved/deleted during reboot.
  • After reboot, post the contents of the log from Dr.Web in your next reply. (You can use Notepad to open the DrWeb.cvs report)

And
TrendMicro™ HouseCall Java Scan
  • Please go HERE to run the Trend Micro™ HouseCall Scan.
  • Click Scan now. It's free!
  • Read and put a Check next to Yes I accept the terms of use.
  • Click the Launching HouseCall>> button.
  • If confirmed that HouseCall can run on your system, under Using Java-based HouseCall kernel click the Starting HouseCall>> button.
  • You may receive a Security Warning about the TrendMicro Java applet, click YES.
  • Under Scan complete computer for malware, grayware, and vulnerabilities click the Next>> button.
  • Please be patient while it installs, updates, and scans your system.
  • Once the scan is complete, it will take you to the summary page.
  • Under Cleanup options, choose clean all detected infections automatically.
  • Click the Clean now>> button.
  • If anything was found you may be prompted to run the scan again, you can just close the browser window.

Hello, Boopme. Thanks for the reply. Couldnt get dr web cure it to complete the 'complete scan'. When it would progress to about 25% I get a pop up saying "setup.exe has encountered a problem and needs to close. sorry for the inconvenience". Tried it twice too.

I'll do the trend micro scan now.

Great !! and you are welcome. :thumbsup:

Now you should Create a New Restore Point to prevent possible reinfection from an old one. Some of the malware you picked up could have been saved in System Restore. Since this is a protected directory your tools cannot access to delete these files, they sometimes can reinfect your system if you accidentally use an old restore point. Setting a new restore point AFTER cleaning your system will help prevent this and enable your computer to "roll-back" to a clean working state.

The easiest and safest way to do this is:
  • Go to Start > Programs > Accessories > System Tools and click "System Restore".
  • Choose the radio button marked "Create a Restore Point" on the first screen then click "Next". Give the R.P. a name, then click "Create". The new point will be stamped with the current date and time. Keep a log of this so you can find it easily should you need to use System Restore.
  • Then use Disk Cleanup to remove all but the most recently created Restore Point.
  • Go to Start > Run and type: Cleanmgr
  • Click "Ok"
  • Disk Cleanup will scan your files for several minutes, then open.
  • Click the "More Options" Tab.
  • Click the "Clean up" button under System Restore.
  • Click Ok. You will be prompted with "Are you sure you want to delete all but the most recent restore point?"
  • Click Yes, then click Ok.
  • Click Yes again when prompted with "Are you sure you want to perform these actions?"
  • Disk Cleanup will remove the files and close automatically.
Vista Users can refer to these links: Create a New Restore Point and Disk Cleanup.
