is related to a rootkit component
, backdoor Trojans
, and IRCBots
are very dangerous
because they compromise system integrity
by making changes that allow it to be used by the attacker for malicious purposes. Rootkits are used by 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 bypasses 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 again. Banking and credit card institutions should be notified of the possible security breach. Because your computer was compromised please read:
Although the rootkit was 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:
Should you decide not to follow that advice, we will do our best to help clean the computer of any infections but we cannot guarantee it to be trustworthy or that the removal will be successful
. If you wish to proceed, please do the following.
