Computer Trojan Problem, need help ASAP?

Question

A little bit earlier today I put Avira back on my computer, and not but 5 minutes or so after it was installed I get a message saying TR/DNSChanger.VJ.2 was found on my computer. Tried to get rid of it with Avira but it keeps coming back each time. So looked on the answers board and found I can get rid of it with Emsisoft Emergency Kit 1.0. Well after hours of scanning with that, it finds it, puts it in quarantine then says I need to restart, welll during restart my computer cannot even restart and failed a good 3 times till I just ran the repair mode. Now all the anti vir /malware programs are gone (because the reboot from repair mode). I need help FAST on how to get rid of this trojan/virus and fast, this thing is reaking havoc on my comp!

Answer 1

Try Live CD Antivirus Scanners, they will scan your computer without starting Windows.

If all fails, you may need to do a complete reinstall.

Actually, if I were you, I would just go for the reinstall, it is the most painful solution, but it will definitely fix it.

Answer 2

Boot in safe mode with networking by tapping the F8 key repeatedly the moment you turn your computer on.



Read what RKill is all about and how it is used. Download a copy and run it: http://www.bleepingcomputer.com/download/anti-virus/rkill



After that, download and run Malwarebytes' Anti-Malware: http://www.malwarebytes.org/products/malwarebytes_free



Update MBAM before doing a full scan.



You may also run this in case you have a rootkit that redirects your google searches:

If that didn't work as the infection is still blocking you, you need to do it externally. Download this bootable CD on another computer:

http://www.hirensbootcd.org/download/



Extract the zipped file to a temporary folder and run the BurnToCD command to transfer the contents to a CD.



Go back to your infected computer and boot from the CD. Make sure you set your BIOS to boot from the CD/DVD drive and not the hard drive.



Run the Mini Windows XP OS. When inside, open the browser and download Malwarebytes Anti-Malware:

http://www.malwarebytes.org/products/malwarebytes_free



Install and update it before doing a full scan.



Take note that MBAM is not a substitute for an antivirus as it is just an antispyware. You will still need to scan your computer with a decent AV after you have regained control of your computer. This is a good one and is free:

Keep everything updated including your OS.



By the way, the Mini Windows XP also comes with a small version of Avira Antivir program which you can use as scanner but you need to update the virus definitions.

Answer 3

If you dont want to do a fresh install, you could try making a thread of youre own at the Avira forums. Someone there will run through everything with you...like this one.....



http://forum.avira.com/wbb/index.php?page=Thread&threadID=137343



Please, if you are not an expert, dont just go through others threads and run these programs without guidance as they may not be the right ones for youre specific infection, and you can do even more damage.

Answer 4

There may be one more infection assosiated with it.



. To check it's presence you have to do one thing.



In Windows XP

----------------------



Click on the start meanu and press on Run.

Inside the Run window type CMD and press on Okay.

In the black Command Window type

NETSH WINSOCK RESET and hit on enter.



If you get a message

"Sucessfully reset the Winsock Catalog.

You must restart the machine in order to complete the reset." then you are safe.

If not your computer is infected. The only solution to fix it is a Fresh Installation.



In Windows Vista and Windows 7

--------------------------------------…



Click on the Start Menu and in the Search box type CMD

At the top you can see a CMD file. Just right click on that file and select Run as



Administrator.



In the black Command Window type

NETSH WINSOCK RESET and hit on enter.



If you get a message

"Sucessfully reset the Winsock Catalog.

You must restart the machine in order to complete the reset." then you are safe.



If not your computer is infected. In windows Vista and Windows 7 a successful system restore



will fix the issue. Try a system restore to a good point.



After a successful system restore try to do the same step again.

If you got the message "Sucessfully reset the Winsock Catalog.

You must restart the machine in order to complete the reset." your computer is safe and secure.

Answer 5

TR/DNSChanger is a trojan that changes default DNS settings. Reset DNS settings and this should be enough. Also, I think you should scan your computer with anti-malware software. It's very similar to the 'rediret' virus, you may follow this removal guide http://deletemalware.blogspot.com/2010/02/remove-google-redirect-virus.html

Answer 6
