Help Removing Trojan-BNK.Win32.Keylogger.gen

Fri Apr 15, 2011 4:01 pm

OK so I turn on the computer this morning I get what appears to be a legit Win7 warning that my computer is infected withTrojan-BNK.Win32.Keylogger.gen, try to log in to the internet to see what this is about but it will not let me, saying that Win7 has detected my computer is infected with this and will not let me log on to the internet because my personal information (credit card bla bla bla) is at risk of being stolen.

Tried to run Windows Defender and Windows Security Esentials but these did not work, ran Malwarebytes anti-malware and it froze before finding anything.

Took another computer to check this and it appears (according to what I found online) it is not a real virus but spyware that tries to fool you in to thinking your PC is infected and you need to upgrade to another security program, bingo! it asks you to purchase with a credit card this product.

Does anyone know how can I remove this? I googled for an answer but so far I can only find insturctions on how to do this manually but since I'm not an IT guy I do not wish to start removing programs without know what I'm doing.

Can't log in to internet as this will not let me, and can't run MS security essentials either to scan my computer for viruses and spyware.

One suggestion here with detailed instructions

You need to download various programs to a "clean" computer before using them on the compromised one.

Tried that....I have internet access now but both antivirus and antispyware are still not working.....thinking of uninstalling both and reinstalling them to see if that fixes it.

Won't work.

And you have a keylogger, so don't even *think* about logging on to your email on the infected computer, or typing anything even remotely close to your password(s).

Give the link below a shot. Report back on what happened. Better yet, use a clean computer to join Bleeping Computer and post there. They have hundreds of people that will help, walk you through everything from start to finish, as opposed to the two or three that might help here on A.net.

I'm happy to help you out either way, though - up to you on which route to take.
The above post is my opinion. Don't like it? Don't read it.

Been there, done that, a million times (if its the one I'm thinking at least)

Anyways...

Download Rkill. Run. Wait for it to do its thing (it may seem to freeze for a bit, dont panic)
Reboot into safe mode.
Run full scan with malwarebytes (make sure database is updated)
Problem solved.

Also, monitor the task manager (ctrl-shift-esc) and see if you find any weird programs with a generic 3 letter name and kill it. something like abc.exe or xyz.exe etc etc. That should disable it temporarily and long enough for you to download some programs to fix it in the meantime.

Donwloaded and ran Rkill, it froze like nothing happened and I left it as is for a few minutes, then I restored the system to 5 days ago, then I instaled AVG and reinstaled malwarebytes anti-malware....so far it has found nothing. AVG did not find anything either.

When malwarebytes finishes I will do the same with SUPERAntiSpyware and see.

Thank you for your help.

Hmm, this is a tough one then.

How good are you with computers? You could run Linux off a USB drive and scan your windows files from the linux envrionment.

Quoting Marcus (Reply 5):

From my experience that tends to make things worse.

Quoting Marcus (Reply 5):

Try avast.I had AVG and it let many viruses through. I knowingly frequent, uhm, how to put it, very questionable websites (in terms of security) frequently, And avast has never failed me. And I've tried every major antivirus out there.

Also, are you absolutely sure it's a legit warning and not one of those self installed fake antivirus programs?

Had this happen to me about a year ago (with Vista)

It's not a legit warning from Windows, though you do have a trojan or two running amok. And by two I mean probably a dozen or so.

Quoting Marcus (Thread starter):

Run it in safe mode, then run it in normal mode, then safe mode again. It will take several passes to clear up.

System restores do not remove any files or programs, so they are useless for getting rid of viruses and trojans.

Make sure you have the latest definitions. Try running it as an administrator also.

You are correct, I googled it and it appears is not a real problem but a trojan designed to scare you in to thinking you have a very serious problem with your system.

When it prevents you from accessing the internet (IE and Firefox) it recommends you buy an upgraded antivirus program, it then takes you to one of those "put all your personal and credit card information in this page so you can clean your computer with what we are selling"; I did not fall for it but I must say that it looks really really legit.

Ran MS security essentials, AVG, Avast, Malwarebytes anti-malware, SUPERAnti spyware, ESET and TFC; SUPERA and Avast did find things that other programs missed.

Computer seems to be OK now, but I think it is a bit slower that before.....

I have found it completely removes the infection.

Quoting Maverick623 (Reply 7):

System Restore restores your system folders and registry back to the way they were at the selected point, thereby removing any new files/entries that were added. this is where most viruses hide, and therefore a system restore will remove them.

I have done this on two seperate PCs that had similar infections, and it worked both times. Just make sure you go back to a point before you got infected, but most viruses tend to spring up straight away, so going back just a day or two should be enough.

Just reformat your drives and reinstall the Operating System from a known good source.
Backup first only your personal stuff or data.

Theres noting one can do to fix a massive infection. You will just run into more added problema while cleaning the infection.

Trust me, I know it will take you almost all day to reinstall, but most PC securtiy experts would aggree on this.

Most modern Trojans or virsuses nowadays dig deep into your system so its very very impossible to clean the PC 100% free.....

Good Luck.

That should be your absolutely last resort.

I run Avast and Malwarebytes and I do relatively well that way. But what I've learned over the years is to store my files externally. I barely have anything on the internal hard drive, everything important to me is kept on the external in the event that a reformat becomes necessary.

Yes I know, but I ran into a alot of people who destroyed their PC just trying to remove a virus.
Its a huge heacache, and so is reinstalling Windows. But it pays off.

Thats why everyone should image their system incase something like this happens.

You cannot destroy your PC while trying to remove a virus, however you could destroy your windows install, at which point you do a reinstall anyway. Far better to attempt to clean the virus first, then do a reformat as a last resort.

Do a system restore, it has worked for me recently.
