! Welcome to BleepingComputer Forums
My name is Georgi
and and I will be helping you with your computer problems.
Before we begin, please note the following:
- I will working be on your Malware issues, this may or may not, solve other issues you have with your machine.
- The logs can take some time to research, so please be patient with me.
- Stay with the topic until I tell you that your system is clean. Missing symptoms does not mean that everything is okay.
- Instructions that I give are for your system only!
- Please do not run any tools until requested ! The reason for this is so I know what is going on with the machine at any time. Some programs can interfere with others and hamper the recovery process.
- Please perform all steps in the order received. If you can't understand something don't hesitate to ask.
- Again I would like to remind you to make no further changes to your computer unless I direct you to do so. I will not help you if you do not follow my instructions.
: One or more of the identified infections is related to the rootkit ZeroAccess
, backdoor Trojans
, and IRCBots
are very dangerous
because they compromise system integrity
by making changes that allow it to be used be the attacker for malicious purposes. Rootkits are used be Trojans to conceal its presence (hide from view) in order to prevent detection of an attacker's software and make removal more difficult. Many rootkits can hook into the Windows 32-bit kernel, and patch several APIs to hide new registry keys and files they install. They can disable your anti-virus and security tools to prevent detection and removal
. Remote attackers use backdoors as a means of accessing and taking control of a computer that bepasses security mechanisms. This type of exploit allows them to steal sensitive information like passwords, personal and financial data which is send back to the hacker. To learn more about these types of infections, you can refer to:
If your computer was used for online banking, has credit card information or other sensitive data on it, you should stay disconnected from the Internet until your system is fully cleaned. All passwords should be changed immediately
to include those used for banking, email, eBay, paypal and online forums. You should consider them to be compromised
and change each password using a clean computer, not the infected one. If not, an attacker may get the new passwords and transaction information. If using a router
, you need to reset it with a strong logon/password so the malware cannot gain control before connect again. Banking and credit card institutions should be notified of the possible security breach. Because your computer was compromised please read:
Although the infection has been identified and may be removed, your PC has likely been compromised and there is no way to be sure the computer can ever be trusted again. It is dangerous and incorrect to assume the computer is secure even if the malware appears to have been removed
. In some instances an infection may have caused so much damage to your system that it cannot be completely cleaned or repaired so you can never be sure that you have completely removed a rootkit. The malware may leave so many remnants behind that security tools cannot find them. Tools that claim to be able to remove rootkits cannot guarantee
that all traces of it will be removed. Many experts in the security community believe that once infected with this type of malware, the best course of action is to wipe the drive clean, reformat
and reinstall the OS. Please read:We can still clean this machine but I can't guarantee that it will be 100% secure afterwards. If you decide to continue please do this:
Please download ComboFix
from the link below:Combofix
Save it to your Desktop <-- Important!!!
- Disable your AntiVirus and AntiSpyware applications, usually via a right click on the System Tray icon. They may otherwise interfere with our tools. Please refer to this link for instructions.
- Double click it & follow the prompts.
- If you receive a UAC prompt asking if you want to continue running the program, you should press the Continue button.
- When finished, it will produce a log for you.
- Please include the C:\ComboFix.txt in your next reply.
- Note: After running Combofix, you may receive an error about "illegal operation on a registry key that has been marked for deletion." If you receive this error, please reboot and it should disappear.
- If you no longer have access to your Internet connection after running ComboFix, please reboot to restore it. If that does not restore the connection, then follow the instructions for Manually restoring the Internet connection provided in the "How to Guide" you printed out earlier.
-- Do not touch your mouse/keyboard until the ComboFix scan has completed, as this may cause the process to stall or the computer to lock.
