Hi,

as you can tell by the name, I am relatively new (mostly to this forum).
Anyways, I have a virus ( i believe it is the trojan variety ) and its been a pain to remove.
I'm not exactly sure what to do now, and decided to post here and see if anyone can help.

So I guess I'll explain what this virus is doing...
1. It changes my background to this weird Ad-like message:
WARNING!! your computer may...blah blah...
and it doesn't allow me to change the background too...
2. It disables my Task manager, so i can't end anything suspicious...
3. It creates some new icon (near the clock, bottom right) that tells me to install some virus scanner
-i know its fake, but clicked it and it pops an website for me (disabled internet btw)

and after trying to clean/scan/reboot endlessly, the problem still persists! What i delete/remove earlier, just comes crawling back...
I used the following to scan/clean:
-S & D
-Ad-aware
-Nod32

Ah dam...I read the BEFORE YOU POST thread too late...can't change the topic title.
Anyways, while scanning i noticed the following .dll that I found were harmful ( i think )
-doguzeri.dll
-yoyijite.dll
I tried to clean/remove these using HJT. but the just come back

So if anyone can help, i'll be more than appreciated.
Thanks!

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:

Did your anti-virus/anti-spyware scanner provide a specific file name associated with this malware threat(s) and if so, where is it located (full file path) at on your system?

services.exe is the Services Control Manager process which interacts with and manages the operation of starting and stopping system services that are run as processes, as opposed to those run in svchost.exe. It also deals with the automatic starting of services during the computers boot-up and the stopping of services during shut-down. Determining whether services.exe is malware or a legitimate Windows process depends on the location (path) it is running from. One of the ways that malware tries to hide is to give itself the same name as a critical system file. However, it then places itself in a different location on your computer. The legit services.exe file is located in the C:\Windows\System32 folder. If found running from a different location it is malware.

svchost.exe is a generic host process name for a group of services that are run from dynamic-link libraries (DLLs). This is a valid system process that belongs to the Windows Operating System which handles processes executed from DLLs. At startup, Svchost.exe checks the services portion of the registry to construct a list of services that it needs to load. It is not unusual for multiple instances of Svchost.exe running at the same time in Task manager in order to optimise the running of the various services. Determining whether svchost.exe is malware or a legitimate Windows process depends on the location (path) it is running from. The legit svchost.exe file is located in the C:\Windows\System32 folder. If found running from a different location it is malware.

explorer.exe is an executable file for Windows Explorer.

Determining whether a file is malware or a legitimate process sometimes depends on the location (path) it is running from. One of the ways that malware tries to hide is to give itself the same name as a critical system file. However, it then places itself in a different location on your computer.

Anytime you come across a suspicious file for which you cannot find any information about, the file has a legitimate name but is not located where it is supposed to be, or you want a second opinion, submit it to Jotti's virusscan or VirusTotal. In the "File to upload & scan" box, browse to the location of the suspicious file and submit (upload) it for scanning/analysis.
