Hi,
If you have antivirus and another user account on the pc, log in with the other account and run a scan. I've removed that particular virus like that. If not, get on another pc and download Microsoft security essentials offline and make a usb or CD and scan the pc. Link here explains how to make the bootable media and how to perform a scan. http://windows.microsoft.com/en-IE/windows/what-is-windows-defender-offline.

Thanks for the advise but I will not be able to see anything when I plug in the USB with the files on it.

It's a tool that creates a bootable device.
The idea is you create the bootable device and power up your computer and choose boot via that drive, be it CD/DVD or USB, depending on what your system will allow you to boot from.
Some computers will have an option to press F11 or F12 to access the boot menu and you would choose the desired device from there and follow the instructions to scan and hopefully repair your computer from the infection.

Is there any option on the boot screen like "F12 for boot options" ?

Ive seen this one a few times now, if you can get into safe mode, try rolling back your windows updates to the most recent date before you got the virus, it worked on my friends vista machine for me.....

Safe mode keeps shutting down once it opens.

Anyway I kept turning on/off 4 times (by unpluging and the battery) and then it system went into driver repair mode. Came back saying system could not fix problems and sent a report to Microsoft. Anyway after that it gave me option to do a numer of default restores etc then I got the option to scan for affected files after doing it it restarted and worked. Thanks again for all the help.

WIPE your machine and re-install now

HelpWithIT

You can also make a bootable cd which will probably be easier for you as most systems boot from cd-rom by default, if it doesn't then just change the boot up selection in the bios. There is another thread on the boards about this virus...Always good to search the Boards frist..saves your fingers (-;

Helpful advice only please. These viruses can be easily removed usually without the need for such drastic measures.
To help the OP, use a bootable rescue disk like Kaspersky which should pick up the rogue software. Then run Malwarebytes/Super AS to clear up any of the leftovers.

Nick it's Niall - you know I work in Network Security.

We ALWAYS advise our clients to wipe their machines after "removing" a virus. No matter what you do with anti-virus you can never be sure it's fully removed.

Once he has access to his machine again he should take his files from the machine and REINSTALL THE OS anything could still be lurking within no matter what you do.

Re-formatting is a fairly drastic measure to remove these viruses. From experience all they tend to do is drop a exe in the appdata folder/modify some shell startup items in the registry.
Of course you could format and go along with the hassle, it entails, but the reality is that it would be overkill. Not to mention how sure would you be the virus didn't infect any of your files you will be restoring later on... (again a very very slim chance of this happening)

Nick

A friend got this and the following sorted it out.

Start machine in Safe Mode with networking
Download Malware Anti Bytes
Perform Full Scan in the above program
Download CCleaner and bleech bit and clean any residue files
This should clean your machine and back to normal

Then consider about using Linux.

I would have to agree with Nick on this...usually this virus comes from free software/film sites so I find that even after unlocking windows and removing the virus that due to user's previous browsing trends...there are always viruses/spyware of some description left and I would presume that the I.T guy or repair shop would take these steps anyway!! I removed this from a Printing Company's PC on Friday, and found that there were a lot of other viruses/spyware on the system after the Garda Virus removal, it took 4 and a half hours to completely clean the PC and I left him with trial Internet Security Package to use..I guarantee you he preferred this method than to having to reinstall windows from scratch and reinstall all his printing software (some of the cds which he no longer had) which would have taken much longer to do (-;

I've cleared it by removing it from startup, one step. Obviously I cleaned the machine down afterwards, but formatting is a tin foil hat suggestion.

You actually work in Network security and this is your advice? What if the files he takes from his machine are also infected?

There are some great great Av's and anti spyware tools out there at the moment. Getting infected with anything nasty is pretty hard in the first place if you have them installed.

I have not had a single virus or spyware on my pc since installing avast. It makes is pretty damn hard for you to infect your pc and I'd trust them 99.99% if the scans show up no infection.

Avast is all you need really. If you want extra protection go with malwarebytes as well. They are both free and won't conflict with each other. At least the free versions won't.

In your opinion would Avast be better than Security Essentials?

I removed this virus from a computer recently. The virus wouldn't allow me to work in Safe Mode so I did the following:

1. On another computer, download Hitman Pro from the follwing site: http://www.surfright.nl/en/hitmanpro
2. Insert an empty usb drive into computer and the HitMan software should create a bootable USB for you.
3. Insert bootable usb into infected computer, turn on and repeatedly press F11 key to enter boot option (may be a different key on some computers).
4. Select the USB drive to boot from
5. Hitman dialog box should appear. Set it to scan and remove anything found.
6. Restart computer and install MalwareBytes from here: http://download.cnet.com/Malwarebytes-Anti-Malware/3000-8022_4-10804572.html
7. After it is installed, update Malwarebytes, do a full scan and remove any remaining threats
8. Computer should be clean now but download Microsoft Security Essentials and set it to scan daily to reduce chances of reinfection.

Note that Hitman Pro is an aggressive virus remover and has been known to accidentally delete important files so using it is not without risk. It's the only thing that I could find to remove the virus.

Security Essentials BADLY failed another test this week, I'd go with Avast till Microsoft sort it out.

How to Keep Your PC Safe With Sandboxing

Avast is better, mse has failed various tests on pcpro.
see www.pcpro.co.uk it has simply failed to detect certain virus, es .

BloodBath

Avast is far superior to MSE. I'd say almost any AV is better than that.

Avast is updated daily several times a day with the latest definitions and virus database. It automatically scans all downloaded files and all visited websites and blocks any threats.

It opens all new programs in a sandbox, in case they are malicious, so they cannot infect the rest of the system.

I have had 0 issues of any kind in 5 years of pc use since using avast. PC security is pretty important since I pay all my bills online and shop online. My personal and bank details get entered on a regular basis.

There's no way I'd trust that to MSE.

It's a joke in an age where microsoft are charging €80-100 for an os that still doesn't have a reliable av as standard.

It's amazing the response I'm getting from people here.

Yes my advice is to wipe the system.

Lets be realistic here, Antivirus is about 5% effective on new viruses, don't fool yourself.

No wiping your system is not a drastic measure at all. This infection gains root access to your system, generally they will attempt to corrupt the system and leave a 'back door' or if you might know 'rootkit'.

Again generally they attack the OS and not files, if you look at it this way - When attacking a system a hacker wants the most hits per infection (if the virus hits 5000 computers maybe only 10 or 20 will actually be infected).... they attack similarity's amongst systems this is why they look at OS level rather that files, they would be counting on every system having the same file type which is not guaranteed whereas have (for instance) Java installed is highly more likely.

You can take your files off your computer onto an external hard drive.
Now wipe your system, create an administrator account and a user account.
Your daily account should be the user account and never use your admin account.

This is a great level of protection as anything attempt to make system changes under your user account needs admin access and will prompt you for admin password.

Scan your files and check the 'date last modified' again you can't be sure they files haven't been infected but they wont have root access under your new account. I'd generally say your personal files won't be affected (word docs, pdf's, mp3s etc) but as Nick pointed out they might be.






There's a lesson to be learned here, you have to be more vigilant with your system. In the time you were infected somebody could have accessed your system remotely and copied all your files form the system... do you have bank statements on your pc? Do you have a document with personal information? This is unlikely due to the nature of the infection.

At very least create a new account without admin privileges and use this account.... also change your passwords.



The above advice is good... I could write a short document on best practices but I don't really have time at the moment.

1 Patch
2 Use complex passwords
3 Don't use torrents
4 Don't use an admin account for surfing the web
5 Back up your files regularly to an external HDD
