Hi, this is my first post here, but first of all may I just say a big thank you to the members who replied to the many posts that I read which enabled me to fix my problem (I think). I believe that my pc was infected with xp antimalware 2009 as the pc was doing all the things that other posts were complaining about (redirects, not allow updates to spyware or antivirus random restarts etc.etc).
I did manage to run AVG in safe mode which seemed to clear some of the problem but after following the instructions posted here to download, install and run "mbam" my problem seems to be finally cleared up. My problem now is that one of the posts that I read here was in reference to "rootkit TDSS" which as you can see was one of the files found by "mbam" while scanning my pc. The post I refer to talked about how dangerous this malware was and that even if all the malicious symptoms cleared up you could never be absolutely sure that malicious processes were not still running in the background. I use my pc for multiple purposes including banking, shopping, gaming, music, research and communication (yes I did change all passwords). So I guess my question is how safe am I on this pc?.

The infection you have is related to the TDSS rootkit. A warning:

IMPORTANT NOTE: One or more of the identified infections was related to a rootkit component. Rootkits and backdoor Trojan 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, 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 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 breach. Because your computer was compromised please read How Do I Handle Possible Identify Theft, Internet Fraud and CC Fraud?

Although the rootkit was identified and 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. 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:

"When should I re-format? How should I reinstall?"
"Help: I Got Hacked. Now What Do I Do?"
"Where to draw the line? When to recommend a format and reinstall?"

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.

Let me know how you wish to proceed.

I believe I will heed this advice tho it is inconvenient to do an OS reinstall the alternative is surely worse

As I am going to do a clean install of XP I'm of a mind to try and setup a dual boot with Ubuntu Linux, I did try once before with not much success, but I think I'm in the wrong forum for instruction on how to. Will post in appropiate forum. Wish me luck, Thanks for advice with malware.

Try the XP forum. I think you will have more chances to find people who have done it there. Good luck!
