I am really struggling with this computer, wondering where the malware could be hiding that is causing new tabs to open with (mostly gambling sites) in FF. I load FF, open a site, and now and then get a new tab open up with the rogue site in focus.

This computer has been infected with IS2010.exe and IS15.exe plus several others. However, scanners such as MBAM and MSE have seemingly removed all bad files and I cannot get any of about 6 scanners (Trojan Remover, MSE, Trend Micro Housecall, MBAM, SuperAntispyware and Combofix) to find any infections at all. I've also run CCleaner and ATF.

Basically, I have reluctantly written this installation off as it can't be trusted but I am curious as to the mechanism that could be causing the rogue page loads.

Thanks for any insights.

On further study, I think this had the google redirect nasty. TDSS killer found and removed rootkit files so it is 'probably' fixed but still hard to trust it.

IMPORTANT NOTE about: TDSS/TDL3 rootkit.

Rootkits, backdoor Trojans, Botnets, 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, 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 using a clean 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:Although the rootkit was identified and may be removed, your machine 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:
