Yesterday, Zone alarm quarantined a Rootkit.Win32.Podnuha.bxq in my computer. Went online and read about rootkits and now I'm very alarmed. As I understand it, a hacker, using a rootkit, can create backdoors to my computer, which gives them access even after the rootkit has been quarantined. Could not find any info about this particular rootkit when I googled it. Does anyone know anything about it or how it could have gotten into my computer?? I'm thinking of wiping my hard drive clean, but now I'm concerned that the data on my back up hard drive might be infected too. I also read that some of the newer rootkits are so deep in the hard drive that even wiping them clean will not get rid of it. Feel really frustrated and don't know what to do. Any advice would be so appreciated.......

Rootkits are very nasty and hard to repair.

IMPORTANT NOTE: One or more of the identified infections was related to a rootkit component. Rootkits and backdoor Trojan are very dangerous because they use advanced techniques (backdoors) as a means of accessing a computer system that bypasses security mechanisms and steal sensitive information which they send back to the hacker. Many rootkits can hook into the Windows 32-bit kernel, and patch several APIs to hide new registry keys and files they install. Remote attackers use backdoor Trojans and rootkits as part of an exploit to gain unauthorized access to a computer and take control of it without your knowledge.

If your computer was used for online banking, has credit card information or other sensitive data on it, 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. They should be changed by using a different computer and not the infected one. If not, an attacker may get the new passwords and transaction information. Banking and credit card institutions should be notified of the possible security breach. Because your computer was compromised please read How Do I Handle Possible Identify Theft, Internet Fraud and CC Fraud?

Although the rootkit was identified and 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 that because the rootkit has been removed the computer is now secure. In some instances an infection may have caused so much damage to your system that it cannot be completely cleaned or repaired. The malware may leave so many remnants behind that security tools cannot find them. 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:

"When should I re-format? How should I reinstall?"
"Help: I Got Hacked. Now What Do I Do?"
"Where to draw the line? When to recommend a format and reinstall?"

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. Let me know how you wish to proceed.

I would suggest starting in the HJT forum as your best chance of a complete clean. Even then, you may still end up formating and reloading.

Please follow this guide from step (6). Post a HJT log to the HJT forum and a Team member will be along to help you as soon as possible. You may wish to post a link back to this topic to see what was discussed thus far.

If you need any help with the guide, please let me know.
