Hello there and welcome to Bleeping Computer's security forum.
My name is David, I will be helping you with your log today.

Your system is terribly infected. The problem with these infections nowadays is, it causes a lot of damage. Even if we clean the malware off your system, I can't guarantee that your system will be clean afterwards, because these infections/bundles leave a lot of leftovers behind that most scanners won't even recognise and logs won't show. Also, I can't promise you we can repair all the damage it caused... Even after cleaning the malware, you can still get errors afterwards because of the damage. Solving these is not always possible since it will be searching for a needle in a haystack to find the right cause and solution. So, we can try to clean this up and do what we can, but keep in mind that we can't solve ALL problems this malware already caused. Due to the status of some of the files you have on your computer, I strongly recommend that you do the following immediately. Disconnect the infected computer from the internet until the computer can be cleaned. From a clean computer, change all your online passwords-- for email, for banks, eBay, forums etc.... Do not change passwords or do any transactions while using the infected computer because the attacker may get the new passwords and transaction information.

It is a good idea to print off these instructions:
This will be useful as there is a possibility some of the instructions will need to be carried out where internet access is not available.
You may also like to save these instructions in word/notepad to the desktop where they can be easily found for the same reasons as above.
A print out of the instructions would be a good reference to make sure you don't yet lost.
Also, it is important that you complete the instructions in the right order, and also that you don't miss any steps out!
If you have any queries about the process or just general questions, just ask.

You are missing one important program on that computer - an antivirus!
This is somewhat suicidal in today's digital world.
You need to install an antivirus program as soon as you can and run a complete scan of the computer.
AVG and Avast are excellent, free antivirus programs..
Never install more than one antivirus on your system - several together can cause problems and decrease performance.

Please download the Suspicious File Packer from here:
Unzip it to the desktop and run it.

Paste the following bold part into the Suspicious File Packer window:


Allow SFP to pack the file. This will generate a CAB archive on your desktop.
Go to this page.
Enter the url of this thread in the first field.
Where it says, browse to the file that you want to submit, click the browse button next to the second field and browse to the CAB archive that was been created on your desktop.
The cab file will be called requested-files[*].cab (the * stands for the date and hour).
Then click the Send File button below.
Please let me know when you have submitted the files.

Run HijackThis.
On the first menu, click Open the Misc Tools Section
Click Open Uninstall Manager
Click Save List - Save it anywhere.
A notepad will pop-up after it's saved, please copy everything in that Notepad and paste it here.

Download and save Blacklight to your desktop.
Double-click blbeta.exe then accept the agreement.
Click on scan then click next,
You'll see a list of all items found.
Do not choose for rename yet! I want to see the log first; legitimate items can also be present.
There is a log on your desktop with the name fsbl.xxxxxxx.log (the xxxxxxx stand for numbers)
Post the contents of the log in your next reply.
Also post the uninstall list and a new Hijackthis log.

Thank you for your quick reply David. Previously, I was using NAV2005 but it did not allow me to reinstall a 3rd time on the same computer.

After following your instruction...I was unable to install AVG Antivirus because of a known conflict with Roxio EMC version 7 basic so I installed Avast Antivirus. Avast reported that explorer.exe was a virus and could not be repaired so I quarantined it. Am I correct to assume that if I delete this file then I lose an important part of my OS? Please advise.

The status of the explorer.exe file really depends on its location. If the file is in C:\Windows then it should be legitimate, but if it's found elsewhere normally it is bad. Secondly, if you get an option to clean or heal the file you should choose that, as it may be that the legitmate file has been infected. If the real explorer.exe had been quaruntined then probably your desktop would not have loaded on a reboot - no explorer.exe means no desktop in general terms. The only way you could get round this would be if your Windows drew up a replacement file from the cache, but at the moment I don't really know.

If you are able to boot your PC normally, just try and follow the instructions in my previous post.
That will get us on the way to hopefully fixing this badly infected PC.
Good luck :thumbsup:
