Hi. It seems my computer is infected with a trojan that Avast identifies as Win32:Unruy-E. Avast sends a warning when it finds an infected file. After I remove it to chest, a couple of minutes later it re-appers with a new combination of letters. Also, Avast have been sending warnings about infections named Win32:downloader-FFO Trojan and Win32:Dropper-FFB.

Ive done several scans with both avast and Malwarebytes, and removed some of the infections with malware.

Thanks for reading this, and I hope you can help me.

Hello ICYF, Win32/Unruy is a Trojan with file infector characteristics in that it replaces multiple legitimate .exe files (rather than infect them) and downloads more malware to the infected computer.

Let's run these 2 scans and see how we are.

First an online scan:
Please perform a scan with Eset Online Antiivirus Scanner.
This scan requires Internet Explorer,Opera or Firefox to work. Vista/Windows 7 users need to run Internet Explorer as Administrator.
To do this, right-click on the IE icon in the Start Menu or Quick Launch Bar on the Taskbar and select Run As Administrator from the context menu.
  • Click the green Posted Image button.
  • Read the End User License Agreement and check the box:
  • Check Posted Image.
  • Click the Posted Image button.
  • Accept any security warnings from your browser.
  • Check Posted Image
  • Check Remove found threats and Scan potentially unwanted applications. (If given the option, choose "Quarantine" instead of delete.)
  • Click the Start button.
  • ESET will then download updates for itself, install itself, and begin scanning your computer.
  • If offered the option to get information or buy software at any point, just close the window.
  • The scan will take a while so be patient and do NOT use the computer while the scan is running. Keep all other programs and windows closed.
  • When the scan completes, push Posted Image
  • Push Posted Image, and save the file to your desktop as ESETScan.txt.
  • Push the Posted Image button, then Finish.
  • Copy and paste the contents of ESETScan.txt in your next reply.
Note: A log.txt file will also be created and automatically saved in the C:\Program Files\EsetOnlineScanner\ folder.
If you did not save the ESETScan log, click Posted Image > Run..., then type or copy and paste everything in the code box below into the Open dialogue box:

C:\Program Files\ESET\EsetOnlineScanner\log.txt
  • Click Ok and the scan results will open in Notepad.
  • Copy and paste the contents of log.txt in your next reply.
-- Some online scanners will detect existing anti-virus software and refuse to cooperate. You may have to disable the real-time protection components of your existing anti-virus and try running the scan again. If you do this, remember to turn them back on after you are finished.

NOTE: In some instances if no malware is found there will be no log produced.



Rerun MBAM (MalwareBytes) like this:

Open MBAM in normal/regular mode and click Update tab, select Check for Updates,when done
click Scanner tab,select Quick scan and scan (normal mode).
After scan click Remove Selected, Post new scan log and Reboot into normal mode.

Thanks for responding quickly.
I'm not quiet sure if you meant that I should've scanned in safe-mode or not, so if that was the point, give me a hint.

Here is the log from the ESET scan

C:\Documents and Settings\Erland\Application Data\Sun\Java\Deployment\cache\6.0\48\6d7dff30-4bb78afc probably a variant of Win32/Agent.KYOMCBX trojan deleted - quarantined
C:\Documents and Settings\Erland\Application Data\Sun\Java\Deployment\cache\6.0\48\6d7dff30-63fd0a18 Java/TrojanDownloader.Agent.NBY trojan deleted - quarantined
C:\Documents and Settings\Erland\Local Settings\Temp\1BD.tmp a variant of Win32/Olmarik.ANI trojan cleaned by deleting - quarantined

Also did a quick scan with malwarebytes as you requisted. I just found out that I installed it in norwegian, so the log is in norwegian.
However, it found nothing and ill still copy in the log. Since my translation skills are horrible, i'm not gonna try translate, but I think you'll understand the content anyways, since you've most likely done this serveral times. If I need to translate, please tell me to do so.

Ok, good how is it running now.. Looks like EST got the rest. If you want to reinstall MBAM you can do this.

1. Uninstall Malwarebytes' Anti-Malware using Add/Remove programs in the control panel.
2. Restart your computer (very important).
3. Download and run this utility. Mbam clean
4. It will ask to restart your computer (please allow it to).
5. After the computer restarts, install the latest version from here. http://www.malwarebytes.org/mbam-download.php
Note: You will need to reactivate the program using the license you were sent.
Note: If using Free version, ignore the part about putting in your license key and activating.
Launch the program and set the Protection and Registration.
Then go to the UPDATE tab if not done during installation and check for updates.

Alright, its seems like everythings back to normal. Avast havnt been sending any warnings lately. Last warning was around 0:40 AM, which is around 16 hours ago.
Warnings stopped before I before you replied, so it could be random.

If there are no more problems or signs of infection, you should Create a New Restore Point to prevent possible reinfection from an old one. Some of the malware you picked up could have been saved in System Restore. Since this is a protected directory your tools cannot access to delete these files, they sometimes can reinfect your system if you accidentally use an old restore point. Setting a new restore point AFTER cleaning your system will help prevent this and enable your computer to "roll-back" to a clean working state.

The easiest and safest way to do this is:
  • Go to Start > Programs > Accessories > System Tools and click "System Restore".
  • Choose the radio button marked "Create a Restore Point" on the first screen then click "Next". Give the R.P. a name, then click "Create". The new point will be stamped with the current date and time. Keep a log of this so you can find it easily should you need to use System Restore.
  • Then use Disk Cleanup to remove all but the most recently created Restore Point.
  • Go to Start > Run and type: Cleanmgr
  • Click "Ok". Disk Cleanup will scan your files for several minutes, then open.
  • Click the "More Options" tab, then click the "Clean up" button under System Restore.
  • Click Ok. You will be prompted with "Are you sure you want to delete all but the most recent restore point?"
  • Click Yes, then click Ok.
  • Click Yes again when prompted with "Are you sure you want to perform these actions?"
  • Disk Cleanup will remove the files and close automatically.
Vista Users can refer to these links: Create a New Restore Point and Disk Cleanup.

Tips to protect yourself against malware and reduce the potential for re-infection:Avoid gaming sites, pirated software, cracking tools, keygens, and peer-to-peer (P2P) file sharing programs. They are a security risk which can make your computer susceptible to a smörgåsbord of malware infections, remote attacks, exposure of personal information, and identity theft. Many malicious worms and Trojans spread across P2P file sharing networks, gaming and underground sites. Users visiting such pages may see innocuous-looking banner ads containing code which can trigger pop-up ads and malicious Flash ads that install viruses, Trojans and spyware. Ads are a target for hackers because they offer a stealthy way to distribute malware to a wide range of Internet users. The best way to reduce the risk of infection is to avoid these types of web sites and not use any P2P applications. Read P2P Software User Advisories and Risks of File-Sharing Technology.

Keeping Autorun enabled on USB and other removable drives has become a significant security risk due to the increasing number of malware variants that can infect them and transfer the infection to your computer. To learn more about this risk, please read:

Okey, I did what you told me to do since there seems like everything is back to normal.
What do you mean by keeping a log of the system restore, by the way?

The new point will be stamped with the current date and time. Keep a log of this so you can find it easily should you need to use System Restore.
I mean to keep anote of that date somewhere so you know which is the clean point you have to go back and find one on another day.

apparently I cant get into safe mode. My screen turns either black or it's just stuck right before you're supposed to see your background.

I did what you said above in normal mode, and not in safe mode since I couldnt get on.
