Ok, here's the deal. I contracted some type of virus. When I would google something and click on a result, I would be redirected. Also, this bug caused my internal dvd-rw drive to not be recognized. I have a Sony VAIO VGN-NR110E, running Vista Home Premium.

Originally, the bug would not allow me to run Malware Bytes, or properly install any trustworthy anti-virus programs. Through some research, I was finally able to get Malware Bytes to run by changing some file names and extensions. It removed something like 6 files which were infected. I even ran in safe mode and normal mode.

Whatever this thing is, it's still there. I am still redirected from google and other search engines. My DVD-RW drive is not recognized. I am unable to burn any data from the hard drive (and thats fine with me).

What should I do. I am considering re-formating the hard drive, but will that take care of it? What do I need to do this, I've never done it before. I have included the log from malware too, in case it helps, thank you so much

Ok, more info if needed->

I just bought this laptop from a friend, and any data on it is useless to me. I'm willing to re-format. I ran GMER and here is the log:

I tried SUPERAnti-Spyware as well. The log is below. Even in safe mode, this bug is trying to prevent function of any virus removal programs. Every tool I have used, I have had to rename the installation file and the main executable file. This is really pissing me off.

Hello.. This is a serious rootkit bringing in many Backdoor malwares. So I will say this first.

One or more of the identified infections is a backdoor trojan.

This allows hackers to remotely control your computer, steal critical system information and download and execute files.

I would counsel you to disconnect this PC from the Internet immediately. If you do any banking or other financial transactions on the PC or if it should contain any other sensitive information, please get to a known clean computer and change all passwords where applicable, and it would be wise to contact those same financial institutions to apprise them of your situation.

Though the trojan has been identified and can be killed, because of it's backdoor functionality, your PC is very likely compromised and there is no way to be sure your computer can ever again be trusted. Many experts in the security community believe that once infected with this type of trojan, the best course of action would be a reformat and reinstall of the OS. Please read these for more information:

How Do I Handle Possible Identify Theft, Internet Fraud and CC Fraud?
When Should I Format, How Should I Reinstall

We can still clean this machine but I can't guarantee that it will be 100% secure afterwards. Let me know what you decide to do.

If you want to try cleaning ...

Next Please install RootRepeal

Go HERE, and download RootRepeal.zip to your Desktop.
Tutorial with images ,if needed >> L@@K.
Unzip that,(7-zip tool if needed) and then click RootRepeal.exe to open the scanner.
Next click on the Report tab, now click on Scan. A Window will open asking what to include in the scan. Check all of the below and then click OK.

Stealth Objects
Hidden Services

Now you'll be asked which drive to scan. Check C: and click OK again and the scan will start. Please be patient as the scan runs. When the scan has finished, click on Save Report.
Name the log RootRepeal.txt and save it to your Documents folder (it should automatically save it there).
Please copy and paste that into your next reply.

Tried ROOTRepeal. Won't allow it to run. The log is below. I tried renaming the executable, after that I tried to run it. The result said driver couldn't be found.

Not an unwise decision to make. In some instances an infection may have caused so much damage to your system that it cannot be completely cleaned or repaired. Wiping your drive, reformatting, and performing a clean install of the OS or doing a factory restore removes everything and is the safest action but I cannot make that decision for you.

Reformatting a hard disk deletes all data. If you decide to reformat, you can back up all your important documents, data files and photos. The safest practice is not to backup any autorun.ini or .exe files because they may be infected. Some types of malware may disguise itself by adding and hiding its extension to the existing extension of files so be sure you take a close look at the full name. After reformatting, as a precaution, make sure you scan these files with your anti-virus prior to copying them back to your hard drive.

The best proceedure is a low level format. This completely wipes the drive. Then reinstall the OS.
Use the free version of Active@ KillDisk.
Or Darik's Boot And Nuke

The best sources of Information on this are
Reformatting Windows XP
Michael Stevens Tech

Of course also feel free to ask anything on this in the XP forum. They'd be glad to help.
2 guidelines/rules when backing up

1) Backup all your important data files, pictures, music, work etc... and save it onto an external hard-drive. These files usually include .doc, .txt, .mp3, .jpg etc...
2) Do not backup any executables files or any window files. These include .exe's, .scr, .com, .pif etc... as they may contain traces of malware. Also, .html or .htm files that are webpages should also be avoided.

I am seriously considering the reformat. You referenced XP, however I'm using Vista. I backed up all my drivers to a flash drive the other day, and am afraid to use it, as it may contain the bug, therefore transferring it to my system again after reformat. I will reformat, quick and easy question though. Do I need anything other than a clean version of my Vista OS? Drivers etc?

I see that you have posted a log here: http://www.bleepingcomputer.com/forums/topic232350.html I'm not sure why you decided to do that when you were going to reformat. Nonetheless, now that you have a log posted, you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a HJT Team member, nor should you continue to ask for help elsewhere. Doing so can result in system changes which may not show in the log you already posted. Further, any modifications you make on your own may cause confusion for the helper assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.

From this point on the HJT Team should be the only members that you take advice from, until they have verified your log as clean.

Please be patient. It may take a while to get a response because the HJT Team members are EXTREMELY busy working logs posted before yours. They are volunteers who will help you out as soon as possible. It may be a couple weeks before you get a response. Once you have made your post and are waiting, please DO NOT make another reply until it has been responded to by a member of the HJT Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another HJT Team member is already assisting you and not open the thread to respond. Please be patient.

It may take a while to get a response but your log will be reviewed and answered as soon as possible

To avoid confusion, I am closing this topic. Good luck with your log.
