Your computer was infected with a ROOTKIT. In particular, the TDL3 rootkit, also known as Win32/Alureon. A rootkit is a set of software tools intended for concealing running processes, files or system data from the operating system.
Due to its rootkit functionality, it's impossible to tell what may have been done when the system was compromised.
Therefore it may be prudent to:
- Call all your banks, financial institutions, credit card companies and inform them that you may be a victim of identity theft and put a watch on your accounts.
- Change all your passwords (ISP login password, your email address(es) passwords, financial accounts, PayPal, eBay, Amazon, online groups and forums and any other online activities you carry out which require a username and password)

General Security and Computer Health
Below are some steps to follow in order to dramatically lower the chances of reinfection. You may have already implemented some of the steps below, however you should follow any steps that you have not already implemented.
- Make sure that you keep your antivirus updated
New viruses come out every minute, so it is essential that you have the latest signatures for your antivirus program to provide you with the best possible protection from malicious software.
Note: You should only have one antivirus installed at a time. Having more than one antivirus program installed at once is likely to cause conflicts and may well decrease your overall protection as well as impairing the performance of your PC.
Uninstall Tools for Major Antivirus Products
- Security Updates for Windows, Internet Explorer & Microsoft Office
Whenever a security problem in its software is found, Microsoft will usually create a patch so that after the patch is installed, attackers can't use the vulnerability to install malicious software on your PC. Keeping up with these patches will help to prevent malicious software being installed on your PC. Ensure you are registered for Windows updates via Start > right-click on My Computer > Properties > Automatic Updates tab or visit the Microsoft Update site on a regular basis.
Note: The update process uses ActiveX, so you will need to use internet explorer for it and allow the ActiveX control to install.
- Update Non-Microsoft Programs
Microsoft isn't the only company whose products can contain security vulnerabilities. To check whether other programs running on your PC are in need of an update, you can use the Secunia Software Inspector - I suggest that you run it at least once a month.
I would recommend the download and installation of some or all of the following programs (if not already present), and the updating of them on a regular basis.
- Malwarebytes' Anti-Malware
As you already have Malwarebytes' Anti-Malware on board I would keep it regularly updated and run regular quick scans with it. (TIP: Cleaning out temp files can reduce scanning times.)
Malwarebytes' Anti-Malware is an anti-malware application that can thoroughly remove even the most advanced malware. The Full version includes a number of features, including a built in protection monitor that blocks malicious processes before they even start.
- Hosts File
For added protection you may also like to add a host file. A simple explanation of what a Hosts file does is HERE and for more information regarding host files read HERE.
- Use an alternative Internet Browser
Many of the exploits are directed to users of Internet Explorer. Try using a different browser instead:
Finally I am trying to make one point very clear. It is absolutely essential to keep all of your security programs up to date.
