I left my machine running all night. This morning I had a message saying that I had run out of virtual memory and the system would have to allocate more. I then attempted to log on and the pc locked up. So I manually turned the pc off and after rebooting I sent the error to Microsoft and they replied by saying that spooldr.sys caused the malfunction and it may be malware.

I ran full scans with Malwarebytes, Superantispyware and One Care Live as well as SypBot. They all found some spyware and cleaned it up. I then ran ccleaner. Then I downloaded SpyDoctor and it found the following - Trojan-Downloader.Agent.BNZ
Here are the Trojan locations shown by SpyDoctor -

HKEY_USERS\S-1-5-21-790967987-2056272060-316619961-6225\Software\Microsoft\Internet Explorer\New Windows\Allow, ad.doubleclick.net

HKEY_USERS\S-1-5-21-790967987-2056272060-316619961-6225\Software\Google\Navclient\1.1\whitelist, allow2

Do you think the spooldr.sys problem and the trojan are related? How do I get rid of both of them and any other related problems?

Thanks for you help!

Ouch! Spooldr is a very nasty infection if you do have it...

Take a look here: http://www.bleepingcomputer.com/startups/s....sys-19591.html

Posted ImageRootkit Threat

Unfortunatly One or more of the identified infections is a Rootkit/backdoor trojan.

IMPORTANT NOTE: Rootkits and backdoor Trojans 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, you should immediately disconnect from the Internet until your system is 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. You should change each password by using a different computer and 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 How Do I Handle Possible Identify Theft, Internet Fraud and CC Fraud?

Although the rootkit 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 that because this malware 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: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.
