    I was able to use Spybot Search and Destroy to remove this from my system. I updated and scanned. I also ran SS&D upon restart.
    The trojan damaged Microsoft Security Essentials so I had to uninstall and reinstall MSE.

  • Jad az

    How about pressing F8, then clickin on Repair, and restore your computer to an earlier date? that worked for me 🙂

  • johnny

    for anything i should add please email me at johnny.krasnow@gmail.com

    when first noticing my problem i knew the virus had rewritten my registry to open “fyb.exe” before actually opening my program. since the fyb.exe is a fake they obviously wouldnt include the code to open the file you actually wanted after the fact, so your well stuck seeing that stupid screen. So i opened up my other computer and found what code makes all exes open, searched and noticed a slight change. So i wrote the code [listed below] and made a “fix” file for the registry. i got halted by some problems after the quick fix but the program i mentioned fixes it without hassle to much hassle.

    before doing any of this i hope you have firefox or chrome for your web browser, otherwise youll deal with some hugggeee pains after the fact when trying to get tuneup utilities to fix said errors after this quick fix another computer not infected will also work for getting the tune-up utilities trial version to fix all related errors caused by this quickfix.
    (reason for saying this is after you change the registry and try and choose internet explorer then open it will pop up with the “open with” and then try to for some strange reason download iexplorer.exe (still cant figure out why but firefox doesnt have that problem, or chrome, have no idea if opera does. but yeah follow these steps and your problems will be solved.

    go to run type msconfig (a dialog type box should pop up.) go to startup tab and make checkbox next to fyb.exe unchecked so it will not start on startup. press control-alt-delete (you have to hold all 3 buttons down real quick) and terminate process and related components (this is done by right clicking and going to the end process tree button). search for and delete fyb.exe after you remove from startup.
    once you know fyb.exe is no longer running open a notepad file (.txt) and type all this crap in.
    ——————————————————————————————————————-
    Windows Registry Editor 5.00
    [-HKEY_CURRENT_USERSoftwareClasses.exeshellopencommand]
    [-HKEY_CURRENT_USERSoftwareClassessecfileshellopencommand]
    [-HKEY_CLASSES_ROOT.exeshellopencommand]
    [-HKEY_CLASSES_ROOT.exe]
    @=”exefile”
    “Content Type”=”application/x-msdownload”
    [-HKEY_CLASSES_ROOTsecfile]
    ————————————————————————————————————–
    save as fix.reg

    doesnt matter what the name is just as long as you put “.reg” at the end.

    run the file.

    you now should when opening firefox or any of that should get a “open with” box you then if wanting to use firefox find the program mozilla firefox in your program files and open mozilla with the “firefox.exe” you will see you no longer get that stupid win 7 virus crap (meaning you in a sense deactivated that nonsense) the tune up utilities will then correct your issue of you having to choose what programs open with the one your selecting, (thank god i figured that little tidbit out aswell or i could see still being heavily aggravated.

    and apparently tuneup utilities will fix the problem automatically

    (now you might get errors when running this program due to the quick fix, at first i was confused too, so after i opened my tune up and saw it wasnt opening the registrytroubleshooter thing i was like “wait, it opens up a separate exe to access it, so i went to the actual tuneup utility file noticed a few different exes like integrator and such, as well as the one i was looking for. so naturally opened RegistryCleaner.exe in the tuneup utilities file the open with menu popped up so i went to browse went to where that same file is located and as stated selected to open registrycleaner.exe with RegistryCleaner.exe which popped up the cleaner program, I then started a full scan, then let it fix my issue and no more “open with” problem

    neat little program for dealing with errors

    can even find the serial# online through google but I dont condone or recommend that 😛

    but yeah tune-up utilities will automatically fix the errors caused by the quick fix i posted

    so you now have the way to fix the win7security issue, you have the way to fix the open with issue caused by the quick fix i had posted, AND you have a nifty little program which will fix ALOT of different crap and keep your computer running all good and kosher.

    the only thing that pissed me off is when trying to find the way to supposedly fix it someone else also posted near the same thing but didnt say it will screw alot of your stuff up if you dont know what you are doing. so i figured adding that tidbit in would be good…

    hola atcho boy!

    I used registration code 223-298080-3424 with success, tried 1147-175591-6550 it didnt work. My computer is working normal now but wondering if i safe to keep this software on my computer. I cant seem to figure out how to uninstall it.

  • johnny

    The way should be somewhat the same as I had originally posted.

    Hold control+alt+delete a blue screen menu should pop up you then click task manager, a menu of everything your running should pop up. Click on the “processes” tab, a list of program names should be moving around, if you see the program name I listed follow the steps I listed from that point on if you would like to remove it, if the program name isnt there you are going to have to write every one of them down so I can tell you which one it is, and then you would follow the same steps as below but with that program name instead of fyb.exe

    Hope this answer helps ya or that I can help ya in the future, I dont think its all that good to have that thing running as it listed program names that were “corrupt” that actually werent but the fact you got a reg code to work mind boggles me.
