Starting 10/30, pop-ups (mostly false security warnings) have been invasive and I have lost access to my control panel and administration rights. I have tried to follow the directions for posting as well as I could. However, this virus seems to stick around anyway. I've run Ad-Aware several times, and it still finds stuff, even if it runs prior to start-up. I've run Spy-bot several times and it's Smitfraud-C.CoreService that it can't get rid of, no matter what, and it just regenerates all of the other files. I have also tried the Panda Anti-Virus (along with my McAfee) - the other 2 links provided didn't obtain a website. I have also run the Stinger. I then tried to follow up with HijackThis, but it never finishes, it just disappears. Can you help me at all?

Welcome to BC Marniae

Smitfraud-C.Core Service is a rootkit found with certain smitfraud infections and identified by Spybot S&D as Smitfraud-C.CoreService. Rootkits are very dangerous because they use advanced techniques 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 them as part of an exploit to 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 your computer from the Internet until your system is cleaned. All passwords should be changed immediately to include those used for banking, email, eBay and 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 breech.

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 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 reformat and reinstall the OS - "When should I re-format?".

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.

Thank you for responding to my post. The information about this "rootkit" was quite alarming. I have had a friend come and reset the computer as you suggested. So I am now just trying to get everything put back together. Thanks again.
