Dear bleepingcomputer:

About a week ago, I was on yahoo answers, & in a moment of pure stupidity, clicked on a link, thinking it would show me a video of a laptop that I wanted to buy. On the link, I clicked on the video, and a popup came up that said I needed to download activex. I clicked on the "ok", & now my computer is having A LOT of problems. Below is a list of the symptoms:

-Windows does not want to start up, without having to unplug my computer & restarting it several times.
-I can no longer use my spybot. No matter how many times I click on it, it won't start up, even in safe mode.
-Many anti-virus and anti-spyware websites automatically redirected to other sites.
-Computer speed is heavily slowed down.
-I can't put my computer on standby.
-My McAfee doesn't seem to find anything wrong.
-Both Malwarebytes and SuperAntiSpyware can't find anything wrong.
-Upon downloading Spyware Doctor, it said that I have a Trojan.TDSServ in registry value HKEY_LOCAL_MACHINE\SOFTWARE\CLASSES\videoshow|CLSID , but I can't fix it without buying the software.

Can anyone help me please? I already have hijackthis downloaded, & will post a log, upon request.
PLEASE HELP!

Your infection is related to a nasty rootkit component. Rootkits, backdoor Trojans, Botnets, and IRCBots are very dangerous because they compromise system integrity by making changes that allow it to by used by the attacker for malicious purposes. 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 permanent 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, you should 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 and change each password using a clean computer, 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:Although the infection 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 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:

Thank you for your help. I have used my computer for banking, although I use CCleaner on a daily basis. I am also using google incognito as my browser. Two questions:

Does CCleaner help to wipe my passwords clean? I delete browser history everyday, as well as using the cleaner.

Is there any way to take care of this myself, or should I get a professional computer tech. to take care of this? This seems a little over my head. I'm not sure what to do.

Thank you for your help and attention. I always keep autocomplete off for privacy and always wipe the history clean after being on the net. I never save passwords. I'm taking your advice and changing my credit card & bank account passwords from another computer, just to be safe. Now, the next step is getting rid of the virus. Thanks again for all of your help.

Sometimes a reformat or a factory restore is the best solution.

Reformatting a hard disk deletes all data. You can back up all your important documents, personal data files, photos to a CD or DVD drive, not a flash drive or external hard drive as they may become compromised in the process. The safest practice is not to backup any executable files (*.exe), screensavers (*.scr), autorun (.ini) or script files (.php, .asp, and .html) files because they may be infected by malware. Avoid backing up compressed files (.zip, .cab, .rar) that have executable files inside them as some types of malware can penetrate and infect .exe files within compressed files too. Other types of malware may even disguise itself by adding and hiding its extension to the existing extension of file(s) so be sure you look closely at the full file name. After reformatting, scan the backed up data with your anti-virus prior to to copying it back to your hard drive.

If you're not sure how to reformat or need help with reformatting, please review:These links include step-by-step instructions with screenshots:Don't forget you will have to go to Microsoft Update and apply all Windows security patches after reformatting.
Also see How to keep your Windows XP activation after clean install.

Note: If you're using an IBM, Sony, HP, Compaq or Dell machine, you may not have an original XP CD Disk. By policy Microsoft no longer allows OEM manufactures to include the original Windows XP CD-ROM on computers sold with Windows preinstalled. Instead, most computers manufactured and sold by OEM vendors come with a vendor-specific Recovery Disk or Recovery Partition for performing a clean "factory restore" that will reformat your hard drive, remove all data and restore the computer to the state it was in when you first purchased it. See Technology Advisory Recovery Media.

If you need additional assistance with reformatting or have questions about multiple hard drives, you can start a new topic in the Windows XP Home and Professional forum. If you don't get a reply, please send me a PM and I will get someone to take a look.
