Fake avast! Antivirus: Avast-antivirus-francais.exe

Cyber-criminals are attempting to benefit from unexperienced web users who are looking for anti-virus software. We found a couple of misleading websites in French language that distribute rogue avast! Antivirus installer Avast-antivirus-francais.exe.
  • avastantivirus2011.com
  • avastfrance.com


We ran the installer and were immediately prompted to send an SMS to a premium number (3.99 Euros) in order to get our activation code which allows us to continue the installation. That's a very shady practice, especially when you can download and install avast! Antivirus from the official website absolutely for free. Perhaps even more interesting fact is that scammers include a link to the official avast! website at the bottom of their misleading web pages. Scammers also explain that they offer a verified and virus free download link for 3.99 Euros. The key takeaway of this story: do not download software from non-official websites. You can download avast! Antivirus from avast.com. Good luck and be safe online!

    Remove Trojan.Ransomware (Uninstall Guide)

    Trojan.Ransomware is a piece of malware that hijacks your computer and demands payment in exchange for the unlock key. If you don't have the key, you can't do anything. Very often, ransomware locks Windows in Safe Mode and Safe Mode with Networking too; otherwise you could easily get rid of it. However, there are a couple of steps that you can generally follow to get rid of the majority of Trojan.Ransomware type infections.

    A few days ago we ended up with a specific Trojan.Ransomware that targets Russian web users. It hijacks the computer and displays a message in Russian saying that you need to send and an SMS on given number to retrieve the activation code.





    We got it from a fake porn website that prompts web users to install pornoplayer.exe in order to watch requested video.





    Of course, that doesn't mean you are protected against such malware just because you live in U.S or Europe. It can hijack your computer as well. So, let's say your PC is locked, you don't understand anything in Russian and you can't use their phone number. What would you do? Please follow the general Trojan.Ransomware removal guide below.


    Trojan.Ransomware removal instructions:

    1. Reboot your computer is "Safe Mode with Command Prompt". As the computer is booting tap the "F8 key" continuously which should bring up the "Windows Advanced Options Menu" as shown below. Use your arrow keys to move to "Safe Mode with Command Prompt" and press Enter key. Login as the same user you were previously logged in with in the normal Windows mode.



    2. When Windows loads, the Windows command prompt will show up as show in the image below. At the command prompt, type explorer, and press Enter. Windows Explorer opens.



    3. Then open the Registry editor using the same Windows command prompt. Type regedit and press Enter. The Registry Editor opens.



    4. Locate the following registry entries:

    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon

    In the righthand pane select the registry key named Shell. Right click on this registry key and choose Modify.



    Default value is Explorer.exe.



    Modified value data points to Trojan.Ransomware executable file.



    If Trojan.Ransomware modified the Shell value data, please copy the location of the executable file it points to into Notepad and then change value data to Explorer.exe. Click OK to save your changes and exit the Registry editor. Proceed to step 5.

    If the default value data (Explorer.exe) wasn't modified, please locate the second registry entry:

    HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run

    In the righthand pane select the randomly named registry key. In our case it was 22997148.



    Copy the location of the executable file into Notepad and then delete the registry key. Right click on the registry key and choose Delete. Click Yes to confirm and exit the Registry editor. Proceed to step 5.

    5. Delete Trojan.Ransomware files. Use the file location you saved into Notepad or otherwise noted in step 4. In our case, Trojan.Ransomware resided in %UserProfile% directory. There was a randomly named folder 22997148.

    Full path: C:\Documents and Settings\Michael\22997148\22997148.EXE



    NOTE: %UserProfile% refers to:
    C:\Documents and Settings\[UserName] (for Windows 2000/XP)
    C:\Users\[UserName]\ (for Windows Vista & Windows 7)

    6. Go back into "Normal Mode". Download recommended anti-malware software (direct download) and run a full system scan to remove this virus from your computer.


    Associated Trojan.Ransomware files and registry values:

    Files:
    • %UserProfile%\[SET OF RANDOM NUMBERS]\
    • %UserProfile%\[SET OF RANDOM NUMBERS]\[SET OF RANDOM NUMBERS].exe
    %UserProfile% refers to:
    C:\Documents and Settings\[UserName] (for Windows 2000/XP)
    C:\Users\[UserName]\ (for Windows Vista & Windows 7)

    Registry values:
    • HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run "[SET OF RANDOM NUMBERS]"
    • HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon "Shell = [SET OF RANDOM NUMBERS]"
