Anecdotal (1 PC only), but real fix. wXPhome, old dell tower-but fairly fast nonetheless. Friend could not access the net at all, kept getting the typical ransomware msgs. This is on 11oct13. 

-Due to previous malware repair, I had installed MSE, mbam & SAS.  On the previous prob. MSE was not there, & put in after the fact. I used RKill then & MSE overcame the malware after.  This time - no need to run RKill. Booted to admin (full boot not f8), MSE found av security pro ransomware & got rid of it, or at least allowed internet access (it kept cleaning x3 incidents, hence the doubt). Updated mbam free ran it. It found about 27 pieces of malware & got rid of them, incl. medfos.  Ran SAS.  It found about 200 spyware "pieces."  This only took about 1/2 hour! I'm as surprised as you are.

This is available as a Bleeping Tutorial
Many of these rogue programs do have removal tutorials listed now.

There are also several versions of Ransomware Removal in the Tutorials


Thank You -

Ran SAS. It found about 200 spyware "pieces."

Without viewing the log, I would suspect those detections were most likely related to cookies if you did not change the default scan settings.


Win32/Medfos is a family of trojans that install malicious extensions for Internet browsers and redirect search engine results. It also allows for click-fraud, generating profit for a website through unethical means.

To double-check for malicious and junk browser extensions and add-ons...I recommend you do the following.

Please download AdwCleaner by Xplode and save to your Desktop.
  • Double-click on AdwCleaner.exe to run the tool.
    Vista/Windows 7/8 users right-click and select Run As Administrator.
  • Click on the Scan button.
  • AdwCleaner will begin...be patient as the scan may take some time to complete.
  • After the scan has finished, click on the Report button...a logfile (AdwCleaner[R0].txt) will open in Notepad for review.
  • Click on the Clean button.
  • Press OK when asked to close all programs and follow the onscreen prompts.
  • Press OK again to allow AdwCleaner to restart the computer and complete the removal process.
  • After rebooting, a logfile report (AdwCleaner[S0].txt) will open automatically.
  • Copy and paste the contents of that logfile in your next reply.
  • A copy of all logfiles are saved in the C:\AdwCleaner folder which was created when running the tool.
-- Note: The contents of the log file may be confusing. Unless you see a program name that you recognize and know should not be removed, don't worry about it. If you see an entry you want to keep, return to AdwCleaner before cleaning...all detected items will be listed (and checked) in each tab. Click on each one and uncheck any items you want to keep (except you cannot uncheck Chrome and Firefox preferences lines).

Please download Junkware Removal Tool thisisujrt.gif and save it to your Desktop.
  • Close all open programs and shut down any protection/security software now to avoid potential conflicts.
  • Double-click on JRT.exe to run the tool.
    Vista/Windows 7/8 users right-click 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 file named JRT.txt will automatically open and be saved to your Desktop.
  • Copy and paste the contents of JRT.txt in your next reply.
