Hello there. I'm new, and I have a very, very bad problem. I've posted about this matter on TSF, but it's been a week and I've had no reply, so I thought I'd try here as well (seeing as I'm desperate).

Almost two weeks ago now, I was doing a search on Google, and accidentally clicked on the wrong result. It took me to a page that didn't load and Chrome gave me a message that said my computer was infected. At the time, I had Avast! and SpyBot installed and neither program detected anything, so I thought nothing of it at first. But then after that, every time I went to close Chrome, I got a message that asked me if I was sure I wanted to close as there were downloads still in progress. I hadn't been downloading anything. I gave the trial scan of Webroot SpySweeper a try (as well as its Desktop Firewall product) and it found only Spy Cookies. Webroot Desktop Firewall works great, but I get a notice saying it's blocked something around every three seconds, which seems abnormal. As well, when I'm out of Safe Mode (with Networking) most things crash or just don't respond, and my USB stick has been visibly infected. My computer is also working at about 1/10th of its normal speed.

I'm really worried, because I have no backups of anything saved (I just learned of that Vista feature today - I'm very computer-stupid), and as I said, my flash drive files are infected (so anything I save to it comes out unreadable and un-deleteable). It's only getting worse, and I would be eternally grateful to anyone who could help me.

Hello and welcome to Bleeping Computer.

Please subscribe to your topic so that you will be notified as soon as I post a reply, instead of you having to check the topic all of the time. This will allow you to get an email notification when I reply.

To subscribe, go to your topic, and at the top right hand corner by your first post, click the Options button and then click Track this topic. The bullet the immediate notification bubble. Then press submit.



Lets take a look with Malwarebytes

Please download Malwarebytes' Anti-Malware from here:
Malwarebytes
Please rename the file BEFORE downloading to zztoy.exe instead of mbam-setup.exe

MBAM may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you. Temporarily disable such programs or permit them to allow the changes.

Double Click zztoy.exe to install the application.
* Make 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 Full Scan", then click Scan.
* The scan may take some time to finish,so please be patient.
* When the scan is complete, click OK, then Show Results to view the results.
* Make sure that everything is checked, and click Remove Selected.
* When disinfection is completed, a log will open in Notepad and you may be prompted to Restart.(See Extra Note)
* The log is automatically saved by MBAM and can be viewed by clicking the Logs tab in MBAM.
* Copy&Paste the entire MBAM report (even if it does not find anything) in your next reply

Extra Note:
If MBAM encounters a file that is difficult to remove,you will be presented with 1 of 2 prompts,click OK to either and let MBAM proceed with the disinfection process, if asked to restart the computer, please do so immediately.


If Malwarebytes won't install or run

Some types of malware will disable MBAM and other security tools. If MBAM will not install, try renaming it. Right-click on the mbam-setup.exe file and change the .exe extension to .bat, .com, .pif, or .scr and then double-click on it to run.

If after installation, MBAM will not run, open the Malwarebytes' Anti-Malware folder in Program Files, right-click on mbam.exe and change the .exe as noted above. Then double-click on it to run.


Also disinfect your flash drives:

Please download
http://download.bleepingcomputer.com/sUBs/...Disinfector.exe
by sUBs and save it to your desktop.
Double-click Flash_Disinfector.exe to run it and follow any prompts that may appear.
The utility may ask you to insert your flash drive and/or other removable drives. Please do so and allow the utility to clean up those drives as well.
Hold down the Shift key when inserting the drive until Windows detects it to keep autorun.inf from executing if it is present.
Wait until it has finished scanning and then exit the program.
Reboot your computer when done.
Note: As part of its routine, Flash_Disinfector will create a hidden folder named autorun.inf in each partition and every USB drive that was plugged in when you ran it. Do not delete this folder...it will help protect your drives from future infection by keeping the autorun file from being installed on the root drive and running other malicious files.

And about disinfecting the flash drives, how big is that hidden file supposed to be? Because even with nothing on my flash drive, it still says more than 5 of the 8 GB is being used.

Its definately not 5GB. I would suggest for you to reformat your USB stick.

But next:

Please run ATF and SAS:

From your regular user account..
Download Attribune's ATF Cleaner and then SUPERAntiSpyware, Free Home Edition

Save both to desktop ..
DO NOT run yet.
Open SUPER from icon and install and Update it
Under Scanner Options make sure the following are checked (leave all others unchecked):
Close browsers before scanning.
Scan for tracking cookies.
Terminate memory threats before quarantining.
Click the "Close" button to leave the control center screen and exit the program. DO NOT run yet.

Now reboot into Safe Mode: How to enter safe mode(XP)
Using the F8 Method
Restart your computer.
When the machine first starts again it will generally list some equipment that is installed in your machine, amount of memory, hard drives installed etc. At this point you should gently tap the F8 key repeatedly until you are presented with a Windows XP Advanced Options menu.
Select the option for Safe Mode using the arrow keys.
Then press enter on your keyboard to boot into Safe Mode.

Double-click ATF-Cleaner.exe to run the program.
Under Main "Select Files to Delete" choose: Select All.
Click the Empty Selected button.

If you use Firefox or Opera browser click that browser at the top and choose: Select All
Click the Empty Selected button.
If you would like to keep your saved passwords, please click No at the prompt.
Click Exit on the Main menu to close the program.

NOW Scan with SUPER
Open from the desktop icon or the program Files list
On the left, make sure you check C:\Fixed Drive.
Perform a Complete scan. After scan,Verify they are all checked.
Click OK on the summary screen to quarantine all found items.
If asked if you want to reboot, click "Yes" and reboot normally.

To retrieve the removal information after reboot, launch SUPERAntispyware again.
Click Preferences, then click the Statistics/Logs tab.
Under Scanner Logs, double-click SUPERAntiSpyware Scan Log.
If there are several logs, click the current dated log and press View log.
A text file will open in your default text editor.
Please copy and paste the Scan Log results in your next reply.
Click Close to exit the program.

Hmmm nothing seems to be detected so far. Lets try Dr. Web.

Please download Dr. Web the free version & save it to your desktop. DO NOT perform a scan yet.

Reboot your computer in "Safe Mode" using the F8 method. To do this, restart your computer and after hearing your computer beep once during startup (but before the Windows icon appears) press the F8 key repeatedly. A menu will appear with several options. Use the arrow keys to navigate and select the option to run Windows in "Safe Mode".

Scan with Dr. Web Cureit as follows:
Double-click on launch.exe to open the program and click Start. (There is no need to update if you just downloaded the most current version
Read the Virus check by DrWeb scanner prompt and click Ok where asked to Start scan now? Allow the setup.exe to load if asked by any of your security programs.
The Express scan will automatically begin.
(This is a short scan of files currently running in memory, boot sectors, and targeted folders).
If prompted to dowload the Full version Free Trial, ignore and click the X to close the window.
If an infected object is found, you will be prompted to move anything that cannot be cured. Click Yes to All.
When complete, click Select All, then choose Cure > Move incurable.
(This will move any detected files to the C:\Documents and Settings\userprofile\DoctorWeb\Quarantine folder if they can't be cured)
Now put a check next to Complete scan to scan all local disks and removable media.
In the top menu, click Settings > Change settings, and UNcheck "Heuristic analysis" under the "Scanning" tab, then click Ok.
Back at the main window, click the green arrow "Start Scanning" button on the right under the Dr.Web logo.
When the scan is complete, a message will be displayed at the bottom indicating if any viruses were found.
Click "Yes to all" if asked to cure or move the file(s) and select "Move incurable".
In the top menu, click file and choose save report list.
Save the DrWeb.csv report to your desktop.
Exit Dr.Web Cureit when done.
Important! Reboot your computer because it could be possible that files in use will be moved/deleted during reboot.
After reboot, post the contents of the log from Dr.Web in your next reply. (You can use Notepad to open the DrWeb.cvs report)

I got Dr. Web Cureit started on a scan, and it picked up a possible trojan (the eMachines game center), but when I started to do the Complete Scan, my computer went to a black screen that said the disks/drives needed to be checked for errors. It restarted the computer, so I tried another scan, and once again two minutes or so into the Complete Scan, a blue screen came up and said the computer needed to shut down. I get one of those screens every time I try to do the scan, and now Safe Mode seems to only load 20 percent of the time. It freezes on the "Loading Windows Processes" screen. Even if I restart Windows normally, I still get one of the screens. Is there anything I can do to avoid them?

I am afraid that Safe Mode and normal mode are the only two ways to boot. This may get back an infection or two that we can try to remove after, and being that you cant boot into safe mode or normal mode most of the time, please instead of Safe Mode, select "Last Known Good Configuration". Does this work?

Last Known Good Configuration just boots the computer up in regular mode, or brings up the black screen again (the one that says something like, "The drives need to be checked for consistency" and then goes onto three different steps). I've found that Safe Mode will work now only when the computer has been shut down or restarted normally.

However, the computer is a lot slower now than it was this morning, and things are starting to freeze in Safe Mode as well. I'm still getting the blue error screen that shuts the computer down a minute or so into the Complete Scan of Dr. Web Cureit.

Your system is awful unstable. Let's not mess with it anymore. instead please:

It looks like we are going to have to use more powerful tools than what we are allowed to use in the Am I Infected forum. I am going to need for you to post a DDS/HijackThis Log in the HijackThis Log section of the forum.

Please refer to this for your preparation reasons before posting:
http://www.bleepingcomputer.com/forums/t/34773/preparation-guide-for-use-before-using-malware-removal-tools-and-requesting-help/

You can find the forum here:
http://www.bleepingcomputer.com/forums/f/22/virus-trojan-spyware-and-malware-removal-logs/

Once you have created a new topic in the HijackThis section, please post a link to it in this topic.
Please allow time for your topic to be replied to in the HijackThis section as the HJT Team is EXTREMELY busy posting logs before yours.

Good Luck!

Hello,

Now that you have a log 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 HJT Team member, nor should you ask for help elsewhere. Doing so can result in system changes which may not show in 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 HJT 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 HJT Team members are EXTREMELY 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 HJT 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 HJT Team member is already assisting you and not open the thread to respond.

Please be patient. It may take several days, perhaps less, to get a response but your log will be reviewed and answered as soon as possible. I advise checking your topic once a day for responses.

To avoid confusion, I am closing this topic. Good luck with your log.

Orange Blossom :thumbsup:
Help us help you. If HelpBot replies, you MUST follow step 1 in its reply so we know you need help.
