My computer was infected with the CLBDriver.sys in the rootkit. It was detected and removed. But, I was told that my computer might not be safe anymore with passwords, using charge cards over the internet, banking info, etc. I was told the 100% safest thing to do is to reformat harddisk and re-instal Windows and sw. ARe there any other options? Since hopefully my computer is clean now. But, I heard that this is a backdoor infection and could still be hiding somewhere? If anybody whom udnerstands this CLBDriver.sys, gretaly appreciate your help!

Yes, Clbdriver.sys is related to a rootkit component. Rootkits 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. 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?" and "Help: I Got Hacked. Now What Do I Do?".
