Win 7 Security Analysis and Removal

by Shanmuga| Tweet This | Google +1 | Facebook | Stumble It | Reddit | Digg |

Win 7 Security is one of the recent rogue security software being installed by Trojan FakeRean. This trojan chooses randomly from a list of names each time it is installed. It has the following list of names for Windows 7:

Win 7 Security, Win 7 Defender, Win 7 Defender Pro, Total Win 7 Security, Win 7 Smart Security 2010, Win 7 Internet Security, Win 7 Security Tool, Win 7 Antimalware, Antispyware Win 7.

A rogue security software such as Win 7 Security belongs to a family of software products that call themselves as antivirus, antispyware or registry cleaners and often use deceptive or high pressure sales tactics and deliberate false positives to convince users into buying a license/subscription. They are often repackaged and renamed. They do not actually remove malware instead many of them add more malware of their own. Users should not fall for the fake alerts and must not buy the scareware. They need to be removed immediately from your system.

Win 7 Security Scareware

Win 7 Security executable

The trojan dropper identified as SHA1:91b06687c5ef5ce690e7e0048843c4ee0d27b692 was about 204288 bytes in size. It is detected by over 75% of the antivirus engines available at VirusTotal.

This trojan drops a file named “ave.exe” with hidden and system attributes in the “local” folder in %appdata% folder. The file ave.exe in turn drops a file without extension named “y7V11” in various system folders. You may need to enable “Show hidden files, folders and drives” and disable “hide protected operating system files” in Folder Options control panel to view these files.

The trojan modifies the Windows registry so that:

  • ave.exe is executed whenever a .exe file is run, it’s a devious way to start with Windows and restart the trojan if it is killed via Task Manager.
  • Sets Internet Explorer as the default browser and sets itself to start whenever IE is started.
  • Hijacks Internet Explorer to display a fake security alert when run.
  • Creates fake Windows Action Center and suppresses genuine Windows Action Center alerts.
  • Disables Windows Firewall

Anonymous April 4, 2010 at 8:21 AM

You can actually access a program while the virus is on the computer without it starting up again by searching for the program in the start button and right clicking “run as administrator” (this is for windows 7)


Anonymous April 27, 2011 at 10:27 PM

Excellent……..I used your suggestion and was allowed my system restore…..and voila….bug be gone…thx much

scott pike February 22, 2011 at 11:08 PM

Thank you for this post it works.


Anonymous March 5, 2011 at 5:15 PM

I accidentally had my antivirus off for performance while running a game and got stricken with this after realizing I hadn’t restarted my antivirus.

Hopefully this information works… thanks for the help!


Asim March 16, 2011 at 7:42 PM

Excellent. It worked very very very well…thank you dear


Dan March 19, 2011 at 10:33 PM

seems overwhelming at first, but it worked perfectly……’s really not to bad, the worst part was waiting for malwarebytes to scan. it took about 30 min on my machine.


Pierre March 23, 2011 at 8:44 AM

great Worked like a charm


Luc March 24, 2011 at 10:35 AM

This virus now also uses the names tyf.exe and onh.exe
I found both these files were being launched every time i opened any program, and the stupid Win 7 Security window came up. Went through and deleted all the files manually as listed above (including the registry edits).

All good now =)


val March 29, 2011 at 12:42 AM

Thank you so very much. These step just made me look very smart in front of a desperate client. Thanks again.

Dude you are sooooo amazing! I was so worried that my computer was about to be messed up for life until I stumbled on this page. And best of all it took little to no time to do!!!!!!!!!!!!


Anonymous April 2, 2011 at 11:59 PM

Niccceee, it worked!!! You’re a computer genius!!! You should change your name to the virus puncher!


Lisa H April 3, 2011 at 9:46 AM

Thank you so much for this, worked great for my laptop.


Dimzin April 4, 2011 at 1:23 AM

T.Y.V.M for the step by step fix for this DISGUSTING infection.
I tried unsuccessfully to remove this manually and totally hooped one of my favourite machines (BSOD everytime I got to the desktop). It would only boot into safe mode. I finally got MS Security essentials to do a complete scan in safe mode and managed to login afterwards w/an admin account, after that I found your page w/another machine and have been following the process step by step, so far so good, MBAWM is currently doing its job and found 9 infections thus far. I sooooo thought I was going to have to completely re-install and lose almost a years worth of tweaking/re-tweaking on my machine.
Will repost w/an update when I`m rid of this evil.


Faisal April 6, 2011 at 12:51 AM

James Pecke April 10, 2011 at 11:14 AM

Thanks. Got the virus right out of my computer. Took most of the day to do it, though (a lot of it spent finding this website), but now the virus is gone. You saved me from having to restore my system. Glad that’s over, I’m gonna warn my friends about this now.


Judy April 10, 2011 at 1:18 PM

This worked for me, after a lot of fiddling:
Firstly, DON’T AGREE to anything it wants you to do. Just keep closing all the windows as they pop up.
1. Ctr-Alt-Delete, Processes tab. Locate the suspicious three letter .exe file (mine was gnx), select it and End Task. This stops it running but it is still in your system. However you should now be able to find it in a search.
2. Open Windows Explorer (right-click Start button and do it this way if it won’t let you do it the normal way), search for the file, and DELETE it. Shift-Delete will remove it completely without sending it to Recycle Bin.
3. Restart. You won’t be able to open several files as your registry is stuffed. Right-clicking and Open as Administrator helps.
4. Do a System Restore to a date before the virus came in. Start, Accessories, System Restore. You might need to right click and Run as Administrator.
5. Restart. It should all be OK now. DON’T open suspicious email attachments again!

i don’t understand set one


Judy April 12, 2011 at 11:25 AM

Probably missed a step.
Ctrl-Alt-Delete, Task Manager, Processes tab.

Wahoo! You guys are the best! I should pay you.

Thanks a ton. Got my computer and internet back!


James Pecke April 13, 2011 at 4:30 AM

Okay, I have a follow-up on my previous comment. While this tutorial does reverse most of the effects of the virus, I’m finding that the virus is never really removed from my system. It has been coming back every day now and it’s honestly getting pretty annoying. Do you have any advice for a more permanent removal of this virus?


Heidi April 23, 2011 at 10:36 AM

This worked!!!! Everything is free!!!


Mike April 26, 2011 at 12:46 AM

@James Pecke… it may be coming back due to the cloned files it creates in your system area or in one of your “Application Data” directories. I initially had the same problem. The file names of the clones are just a string of random characters without extension like “ASJKDJJDUENBDJ”. If you or Malwarebytes doesn’t get all of these AND the registry entries aren’t deleted it may come back. First, run the instructions above to the letter… especially saving and double clicking the .reg file above. When I ran “Malwarebytes” I noticed all of the files it deleted, and the directories it deleted them from. I went to those directories and looked for a file with random letters without extensions that had the same file date and time and deleted it. Then I ran a search for that filename and found one more copy in an “application data” directory and deleted that too. Then I ran CCleaner (free download) to clean out any temp files/cached files, then ran CCleaner’s Registry scan and it found the orphaned registry entries now that the cloned files were gone and deleted them. As a final bit of insurance I ran a FULL Malwarebytes scan again, then let it reboot. Problem solved. Some steps seem redundant, but it worked for me.



vthe April 28, 2011 at 5:08 AM

can somebody help me out, I have done both the first steps in safe mode which are:
■Double click to run the downloaded (trojan_fakerean_exe_fix.reg) registry file, Click Yes to merge the registry data. This will delete the offending registry keys blocking the .exe files.
■Install and run MalwareBytes’s Anti-Malware. Go to the Update tab and check for updates. Once the update is completed, open the Scanner tab and choose a full-scan. Once the scan is completed, click “Show results“, confirm that all instances of the rogue security software are check-marked and then click “Remove Selected” to delete them. If prompted restart immediately to complete the removal process.

the problem with me is that I cannot access properties in comupter (window 7) in order to be able to restore the system off and on

could anybody help me?

It really worked, Thanks for best way of presentation, easy to read and easy to install. Appreciate it


Racerchick May 17, 2011 at 10:15 PM

JUST called SONY Tech Support as I got this virus on my computer thirty minutes ago. My warranty was expired but they said that even warranties dont cover viruses and wanted to charge me $129.18 to get it fixed! I just did a system restore but if this malware pops up again ill be sure to use this method as it seems it works for alot of people! Just dont pay ridiculous amounts of money for no reason is my basic message. Enjoy all!


Zteve May 20, 2011 at 12:45 AM

Thank you, this worked, and CCleaner is doing wonders for my computer as well!


samuel May 28, 2011 at 9:41 PM

Great stuff – just helped a customer with your instructions. Cheers


this is too easy May 29, 2011 at 8:59 AM

it not hard just open task manger and kill the (random 3 letters).exe and run your antivirus it should detect the reg files and delete them easily and if u don’t have an antivirus your are stupid who has an unprotected computer a free antivirus from Microsoft there legit


Susan June 2, 2011 at 12:03 AM
