Hi guys, I started having problems with my computer after I got it back from my mom. System always seems to be running at 100%. Whenever I right click on an icon or even the desk top, a windows installer pops up trying to install winrar. I cannot access my hijack this, unless I go directly to the folder and run the admin exe file. Cannot open any types of browsers either. Any help would be appreciated.

u say u cant do anything on your pc malware is creating obstructions i suppose well we need to remove these obstructions first:

RKill can be downloaded from the following locations. Please note that the other filenames below are RKill as well, just renamed in order to allow it run by certain malware.

here u will get download links for rkill.


When RKill is run it will display a console screen similar to the one below:

That console screen will continue to run until it RKill has finished. Once finished, the box will close and a log will be displayed showing all of the processes that were terminated by RKill and while RKill was running.Post that log here on next reply.




check for malware:


Download Malwarebytes' Anti-Malware (aka MBAM): http://www.malwarebytes.org/products/malwarebytes_free to your desktop.

* Double-click mbam-setup.exe and follow the prompts to install the program.
* At the end, be sure a checkmark is placed next to Update Malwarebytes' Anti-Malware and Launch Malwarebytes' Anti-Malware, then click Finish.
* If an update is found, it will download and install the latest version.
* Once the program has loaded, select Perform quick scan, then click Scan.
* When the scan is complete, click OK, then Show Results to view the results.
* Be sure that everything is checked, and click Remove Selected.
* When completed, a log will open in Notepad.
* Post the log back here.

Be sure to restart the computer.

The log can also be found here:

You have a serious malware infection - ZeroAccess Rootkit. Disinfection will probably require the use of more powerful tools than we recommend in this forum. Before that can be done you will need to create and post a DDS log for further investigation.

Please read the "Preparation Guide".
  • If you cannot complete a step, then skip it and continue with the next.
  • In Step 7 there are instructions for downloading and running DDS which will create a Pseudo HJT Report as part of its log.
When you have done that, post your log in the Virus, Trojan, Spyware, and Malware Removal Logs forum, NOT here, for assistance by the Malware Response Team Experts. A member of the Team will walk you through, step by step, on how to clean your computer. If you post your log back in this thread, the response from the Malware Response Team will be delayed because your post will have to be moved. This means it will fall in line behind any others posted that same day.

Start a new topic, give it a relevant title and post your log along with a brief description of your problem, a summary of any anti-malware tools you have used and a summary of any steps that you have performed on your own. An expert will analyze your log and reply with instructions advising you what to fix. After doing this, please reply back here with a link to the new topic so we can closed this one.

Note: If you cannot create any logs, then still start a new topic, explain that you followed the Prep Guide but were unable to create the required logs. It would also be helpful if you include a description of what happened when you tried to create your logs.


IMPORTANT NOTE: Your scan log results indicate you are using keygens/crack tools.

c:\documents and settings\administrator\local settings\temp\Rar$DR72.440\office_serial_keys_gen.exe

The practice of using cracking tools, keygens, warez or any pirated software is not only considered illegal activity but it is a serious security risk.

Cracking applications are used for illegally breaking (cracking) various copy-protection and registration techniques used in commercial software. These programs may be distributed via Web sites, Usenet, and P2P networks.

trendmicro.com/vinfo

...warez and crack web pages are being used by cybercriminals as download sites for malware related to VIRUT and VIRUX. Searches for serial numbers, cracks, and even antivirus products like Trend Micro yield malcodes that come in the form of executables or self-extracting files...quick links in these sites also lead to malicious files. Ads and banners are also infection vectors...

Keygen and Crack Sites Distribute VIRUX and FakeAV

...warez/piracy sites ranked the highest in downloading spyware...just opening the web page usually sets off an exploit, never mind actually downloading anything. And by the time the malware is finished downloading, often the machine is trashed and rendered useless.

University of Washington spyware study

...One of the most aggressive and intrusive of all bad websites on the Internet are serial, warez, software cracking type sites...they sneak malware onto your system...Where do trojan viruses originate? One of the biggest malware distributors on the Internet are serial/warez/code cracking sites.

Bad Web Sites: Malware

When you use these kind of programs, be forewarned that some of the worst types of malware infections can be contracted and spread by visiting crack, keygen, warez and other pirated software sites. In many cases, those sites are infested with a smörgåsbord of malware and an increasing source of system infection. Those who attempt to get software for free can end up with a computer system so badly damaged that recovery is not possible and it cannot be repaired. When that happens there is nothing you can do besides reformatting and reinstalling the OS.

I strongly recommend that you remove all cracks and keygens immediately to reduce the risk of infection/reinfection. If not, then we are just wasting time trying to clean your system. Further, other tools used during the disinfection process may detect crack and keygens so they need to be removed.

Using these types of programs or the websites visited to get them is very likely how your computer got infected!!

Thanks for your help, I will do as directed. I think my moms boyfriend may have been trying to download something when they had the computer. I just got it back recently. Thank you for the heads up.

Malware topic here: http://www.bleepingcomputer.com/forums/topic412303.html

Now that your log is properly posted, you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a Malware Removal Team member, nor should you continue to ask for help elsewhere. Doing so can result in system changes which may not show it the log you already posted. Further, any modifications you make on your own may cause confusion for the helper assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.

From this point on the Malware Removal Team should be the only members that you take advice from, until they have verified your log as clean.

Please be patient. It may take a while to get a response because the Malware Removal Team members are very busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT make another reply until it has been responded to by a member of the Malware Removal Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another MR Team member is already assisting you and not open the thread to respond.

To avoid confusion, I am closing this topic.
The power of accurate observation is commonly called cynicism by those who haven't got it.

—George Bernard Shaw
