Had trouble with a scareware virus in the last months on my windows xp. Thought we had it cornered, but occasionally the computer would start to lag and run super slow again. When this happened, I would go and delete all the temp files that the computer would allow me to (for some reason Windows wasn't deleting them itself). If it was still slow, we would perform a system restore to the last time it wasn't slow as hell and this would fix the problem. Then this morning, AVG tells me at startup of several Trojans that needed to be quarantined. I obeyed and let it take care of them.

After the restart, several applications were missing from the desktop, including firefox, my computer, our scanning software. AVG also seems to have deleted itself and malwarebytes. Also, windows won't let me place shortcuts for programs that were in the startup menu on the desktop (with the exception of my computer). All the remaining desktop icons were faded and grayish, delineating "hidden" status. I manually unclicked the hidden status in properties for whatever windows would allow. Since this didn't bring back my missing programs, I tried to do a system restore, only to find that my start up menu was missing systems restore and tons of other programs. The SYSTEM TOOLS folder only contains Internet Explorer. I tried a backdoor technique to get to system restore(help and support 'run system restore wizard), but system restore comes up with an error message that says "System Restore is not able to protect your computer. Please restart your computer, and then run System Restore again." I did this, and it changed nothing, still cannot access system restore, even in safe mode.

I should also mention that we've got this message at the bottom right corner that says This copy of Windows did not pass genuine Windows validation. To be honest, I don't know if my version of windows xp is genuine or not, because I didn't install it. This is a work computer. We sort of wrote it off for a while because the virus we had was mimicking this kind of warning. I don't remember what to call it unfortunately (the virus, that is).

Please help.

Can you provide the log from AVG that showed these detections?

Unfortunately, I cannot find AVG on my computer anymore. If it helps, I'm almost certain that they ended in .tmp and said WINDOWS somewhere in the file name. There was about 5 of them.

Hello,

And welcome to BleepingComputer.com, before we can assist you with your question of: Am I infected? You will need to perform the following tasks and post the logs of each if you can. If you have performed any of the scans below post the logs for those scans, and then perform the ones you have not done.

Please download and run Security Check from HERE, and save it to your Desktop.

* Double-click SecurityCheck.exe
* Follow the onscreen instructions inside of the black box.
* A Notepad document should open automatically called checkup.txt; please post the contents of that document.

Malwarebytes Anti-Malware

NOTEMalwarebytes is now offering a free trial of their program, if you want to accept it you will need to enter some billing information, so that at the end of the trial you would be charged the cost of the product. Please decline this offer, if you are unable to provide billing information. If you want to try it out, then provide the billing information.

Please download Malwarebytes Anti-Malware and save it to your desktop.
Download Link 1
Download Link 2MBAM 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.

  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
    For instructions with screenshots, please refer to the How to use Malwarebytes' Anti-Malware Guide.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
MBAM will automatically start and you will be asked to update the program before performing a scan.
  • If an update is found, the program will automatically update itself. Press the OK button to close that box and continue.
  • If you encounter any problems while downloading the definition updates, manually download them from here and just double-click on mbam-rules.exe to install.
On the Scanner tab:
  • Make sure the "Perform Full Scan" option is selected.
  • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
Back at the main Scanner screen:
  • Click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad.
  • The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  • Copy and paste the contents of that report in your next reply. Be sure to post the complete log to include the top portion which shows MBAM's database version and your operating system.
  • Exit MBAM when done.
Note: If MBAM encounters a file that is difficult to remove, you will be asked to reboot your computer so MBAM can proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.


SUPERAntiSpyware:

Please download and scan with SUPERAntiSpyware Free

  • Double-click SUPERAntiSypware.exe and use the default settings for installation.
  • An icon will be created on your desktop. Double-click that icon to launch the program.
  • If it will not start, go to Start > All Prgrams > SUPERAntiSpyware and click on Alternate Start.
  • If asked to update the program definitions, click "Yes". If not, update the definitions before scanning by selecting "Check for Updates". (If you encounter any problems while downloading the updates, manually download them from here. Double-click on the hyperlink for Download Installer and save SASDEFINITIONS.EXE to your desktop. Then double-click on SASDEFINITIONS.EXE to install the definitions.)
  • In the Main Menu, click the Preferences... button.
  • Click the "General and Startup" tab, and under Start-up Options, make sure "Start SUPERAntiSpyware when Windows starts" box is unchecked.
  • Click the "Scanning Control" tab, and under Scanner Options, make sure the following are unchecked (leave all others checked):
    • Ignore files larger then 4mb
    • Ignore non-executable files

    Now Perform the scan with SUPERAntiSpyware as follows:
    • Launch the program and back on the main screen, under "Scan for Harmful Software" click Scan your computer.
    • On the left, make sure you check C:\Fixed Drive.
    • On the right, under "Complete Scan", choose Perform Complete Scan and click "Next".
    • After the scan is complete, a Scan Summary box will appear with potentially harmful items that were detected. Click "OK".
    • Make sure everything has a checkmark next to it and click "Next".
    • A notification will appear that "Quarantine and Removal is Complete". Click "OK" and then click the "Finish" button to return to the main menu.
    • If asked if you want to reboot, click "Yes" and reboot normally.
    • To retrieve the removal information after reboot, launch SUPERAntispyware again.[list]
    • 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.

SAS Portable
If you have a problem downloading, installing or getting SAS to run, try downloading and using the SUPERAntiSpyware Portable Scanner instead. Save the randomly named file (i.e. SAS_1710895.COM) to a usb drive or CD and transfer to the infected computer. Then double-click on it to launch and scan. The file is randomly named to help keep malware from blocking the scanner.


Now GMER

GMER does not work in 64bit Mode!!!!!!

Please download GMER from one of the following locations and save it to your desktop:

  • Main Mirror
    This version will download a randomly named file (Recommended)
  • Zipped Mirror
    This version will download a zip file you will need to extract first. If you use this mirror, please extract the zip file to your desktop.
  • Disconnect from the Internet and close all running programs.
  • Temporarily disable any real-time active protection so your security programs will not conflict with gmer's driver.
  • Double-click on the randomly named GMER file (i.e. n7gmo46c.exe) and allow the gmer.sys driver to load if asked.
  • Note: If you downloaded the zipped version, extract the file to its own folder such as C:\gmer and then double-click on gmer.exe.

    Posted Image
  • GMER will open to the Rootkit/Malware tab and perform an automatic Full Scan when first run. (do not use the computer while the scan is in progress)
  • If you receive a WARNING!!! about rootkit activity and are asked to fully scan your system...click NO.
  • Now click the Scan button. If you see a rootkit warning window, click OK.
  • When the scan is finished, click the Save... button to save the scan results to your Desktop. Save the file as gmer.log.
  • Click the Copy button and paste the results into your next reply.
  • Exit GMER and be sure to re-enable your anti-virus, Firewall and any other security programs you had disabled.
-- If you encounter any problems, try running GMER in safe mode.
-- If GMER crashes or keeps resulting in a BSODs, uncheck Devices on the right side before scanning
.


All scans above should be performed in regular boot mode, and if that is not possible then I will post instructions in a follow up reply on how to get into Safe Mode to perform the scans. Also all scans should be COMPLETE and not quick unless specifically instructed to do so.

This will be a lot more difficult due to the system restores being done, but it is possible. Can you try and locate those logs for AVG?

Also, I don't think my internet is working. Is that a huge problem for Malwarebytes or should I run it without the internet anyway? (I'm checking this forum on a different computer).

Run it anyways and you can follow the manual update process to update the definitions for Mbam.


Please download Farbar Service Scanner and run it on the computer with the issue.
  • Make sure the following options are checked:
    • Internet Services
    • Windows Firewall
    • System Restore
    • Security Center
    • Windows Update
  • Press "Scan".
  • It will create a log (FSS.txt) in the same directory the tool is run.
  • Please copy and paste the log to your reply.

It doesn't say what was actually detected, all i see is registry keys that should have been left alone. What viruses did it detect?

Okay, here they are.

INFECTION Trojan horse Generic26.BXHI
INFECTION Trojan horse Generic26.CBDH
INFECTION Trojan horse Agent_r.AYF
MALWARE Win32/Kryptik.ZOR
MALWARE Win32:Crypt-LNI
MALWARE IDP.Trojan.92B47799
MALWARE Win32:FakeAlert-BXM

Then there are 4 other "viruses" but under "Virus name" it says "The file is signed by an untrusted certificate, issued by: etyy.45e." for all 4 of them.

With those viruses I would recommend that you please follow the instructions in ==>Malware Removal and Log Section Preparation Guide<==.

Once the proper logs are created, then make a NEW TOPIC and post it ==>HERE<== Please include the link to this topic in your new topic and a description of your computer issues and what you have done to resolve them.

If you can produce at least some of the logs, then please create the new topic and explain what happens when you try to create the log(s) that you couldn't get. If you cannot produce any of the logs, then still post the topic and explain that you followed the Prep. Guide, were unable to create the logs, and describe what happens when you try to create the logs.

Once you have created the new topic, please reply back here with a link to the new topic.

Most importantly please be patient till you get a reply to your topic. If you receive a reply from the HelpBot, then please follow the instructions outlined in the helpbot's post.

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 logs 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 Malware Removal Team member is already assisting you and not open the thread to respond.

To avoid confusion, I am closing this topic.
