Hi,
Could someone give me a hand removing the backdoor.tdss.aru trojan?

I noticed google had started redirecting me to other website so downloaded and ran spyware terminator (I've only got AVG antivirus installed) and it found the following:

180searchassistant
windows\system32\TDSSoiqh.dll

It removed 180searchassistant but not the TDSSoiqh.dll


I downloaded malware bytes anti - malware but it wouldn't let me run the installer - I've read you can rename the .exe to either .bat .com or .scr

- haven’t done this yet - as I just wanted to check what's the best way to remove this trojan.

I'm in work at the mo - so on a clean computer and have changed all my passwords and spoke to my bank/credit card people - just in case.

What's the best course of action?

Thanks in advance,
Jim

You need to do a complete disinfection process when you get back to your machine from work.

You may want to consider an alternative to AVG

The following process has proved highly effective please follow it carefully

Please let us know how you get on.


  • Malware is software designed to infiltrate or damage a computer system without the owner's informed consent.
    It is a combination of the words malicious and software.
    The expression is a general term used by computer professionals to mean a variety of forms of hostile, intrusive, or annoying software or program code.

  • Required Cleanup Steps
    1. Disable the Spybot Search & Destroy TEA TIMER if you use it and if it is enabled
    2. Run a Temporary file and cache cleaner (ATF)
    3. Run 2 Anti-Malware scanners (Listed Below)
    4. Run an Online Anti-Virus / Anti-Malware Scanner (Listed Below)
    5. Clear out old System Restore points
    6. If continued Malware type activity is present you may be asked to post a TrendMicro™ HijackThis™ Log file, do not do so unless requested.
The reason to run multiple scanners is to ensure that no single scanner is missing something.
The time it takes will vary depending on your system and your internet connection speed.
Typically the SUPERAntiSpyware and Malwarebytes scanners will take between 10 to 90 minutes.
The ESET online scan should take between 1 to 3 hours.
In most cases, these scans will suffice to clean and disinfect your computer.
Heavily infected systems or slower PCs can take much longer to scan and clean.

Excellent - thanks for that. I've follow ur instructions this eve and report back.

>internet firewall security

What free firewall s/w do you recommend?

Also someone suggested Avira Antivirus as a better alternative to AVG - what do you think?

Thanks,
Jim

Right - went through the steps last night.

It wouldn't allow me to run some of the programs at first until I renamed them.

At step 3 it found 246 files infected (mainly adware) and 80 in the registry
(a harsh lesson in not having any spyware software installed.)

At step 4 it found 10 objects

At step 5 it found 1 file and deleted it.

After that I installed Avira AntiVir and removed AVG. Set up Comodo as my firewall.

System seemed to run a treat after that. MASSIVE THANKS beeceebee! Great advice - given really promptly.

My windows booted up ok and no annoying browser issues. :)

Couple of questions.

1) I started my Avira to do a scan this morning and it found

Boo/Sinowal. A boot sector virus.

I had to pause it before it was 100% and shut it as I had to leave for work.

Is Boo a problem and is there anything I can check this eve to definitely make sure any trojans etc are gone?

2) Also I have a router connected to my computer for wireless for 2 other people in my house. Could anything have been passed over to them via wireless? Housemate had done scan the other day with Norton and found nothing.

Btw your link to ATF-cleaner to snapfiles.com is outdated.

This was definitely a lesson in not having proper spyware & firewall software installed.

Will defo be making a donation as your advice was spot on! :)

Glad it has worked out!!

Regarding your questions:

Allow Avira to remove or quarantine the boo/sinowal virus. It is unfortuanate that you didn't get to finish your scan.

As for the router, it has no hard drive and does not store data that passes through it. Unless your house mates have gone to the same source as you there is no cause for concern.

By the way thanks for the heads up on the link, it will be amended.

- Boo Sinowal

I finished the scan with Avira and it recommended their Antivir Boot Sector Repair Tool or the Antivir Rescue System to fix it.

Downloaded both and tried both. It runs to the point of asking for cd. I've put in several blank cds - the cd spins for a little bit and then windows locks up. Tried this several times but no progress.

Is there another way or another program to remove Boo Sinowal?

Thanks,
Jim

Just doing a google and it seems a few people have cleared up Boo using
Dr.Web Cure It.

is Dr.Web Cure It safe to use? Or effective?

What cd does it ask for?

The windows cd?

It may well be that the repair tool needs burning as an ISO then booting from that.

I doubt a 3rd party program would be asking for you to insert the Windows CD without specifying.

Do both of the programs you mentioned ask for this CD?

Ok that is because you are required to create an iso on a cd. What software do you use to burn CDs and DVDs?

First of all stick with the Avira tools for now. Webcurit is an advanced tool.

Run the exe Removal tool first. Also read the manual first.

Next run the repair tool. You will need to burn it to a CD as an ISO image or to a floppy disk.

After that boot up with the CD or floppy in and follow the steps.

I think I see the problem you are having Phantom.

When you try to run the tool it asks you to put a blank CD in your drive and confirm the device. That is all well and good but will not work since XPcan not simply burn an ISO directly to a disc.

If you exit it will ask you if you want to save it as an ISO and you should say yes to that. After that is complete you must go to where you have saved the ISO and burn that to your CD using Nero.

You should then be able to run the tool.

Ah right - I think that makes sense. :)

So I exit the program - it asks me if I want to save the ISO. I save it somewhere on my h/d.

I then burn that ISO file to a cd. Then I insert that cd once Avira Boot Sector Repair Tool starts up.

Is that correct?

That is correct. Just exit the window where it asks you to put a cd in the drive using the exit button (do not just close the window.) I would simply save it to my desktop.

There is, however one issue.
This is a boot sector repair tool. So once you have burned the ISO you should shut down the pc, put the cd you created into the drive and reboot and follow any directions you may receive. ( I have never seen this tool in action so I have no idea what, if anything , it may ask you to do.)

If that does not work you may have to adjust the boot sequence in your bios. Unfortunatly Avira seems to give little by way of instruction on the site.

Before you concern yourself with the bios, however, first see if the program works when you reboot and if not then try it again after a normal reboot and while you are in windows.
