Over the weekend my computer (HP with XP) was infected. Symptoms were the desktop and shortcuts were not present, just a black screen and everything in the start menu was gone as well. A fake virus scan window would pop up which could not be closed.

I started the computer in safe mode and ran ESETís online scan and it identified a PUM.Hijack.Task Manager. After deletion I was able to start the computer normally and restore my desktop and start menu (most files had been hidden). I ran ESETís online scan again and Malwarebytes scan also. All seems well but I was wondering if there is anything else I can do to make sure 100%. Are there any scan logs that can be examined to ensure there is nothing hiding on my system or am I good to go? I am planning some software upgrades but donít want to proceed if there are still issues. Thanks.

Hi,

After performing these scans, enter the results in your next post and also update me on the status of the PC.

Note: You may have to perform some or all of the following in Safe Mode With Networking, depending on if you have internet access while in the normal Windows environment. If you still don't have internet access in Safe Mode With Networking, you will need to download the installers onto a flash drive from a working computer and transfer them to the problem PC.

Also, if you have any of the following programs already installed on your machine, download the latest version along with updates, then run the scan.


================================================================================

Download Security Check by screen317 from here or here.
  • Save it to your Desktop.
  • Double click SecurityCheck.exe and 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.

================================================================================

Please download and scan with SUPERAntiSpyware Free
  • Double-click SUPERAntiSypware.exe and use the default settings for installation.
    For instructions with screenshots, please refer to the How to use SUPERAntiSpyware to scan and remove malware from your computer Guide.
  • 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 checked (leave all other options as they are set):
    • Close browsers before scanning.
    • Scan for tracking cookies.
    • Terminate memory threats before quarantining.
  • Click the "Close" button to leave the Control Center screen.
  • Back on the main screen, under "Select Scan Type" check the box for Complete Scan.
  • If your computer is badly infected, be sure to check the box next to Enable Rescue Scan (Highly Infected Systems ONLY).
  • Click the Scan your computer... button.
  • 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 scan log after reboot, launch SUPERAntiSpyware again.
  • Click the View Scan Logs button at the bottom.
  • This will open the Scanner Logs Window.
  • Click on the log to highlight it and then click on View Selected Log to open it.
  • Copy and paste the scan log results in your next reply.
-- Some types of malware will disable security tools. If SUPERAntiSpyware will not install, please refer to these instructions for using the SUPERAntiSpyware Installer. If SUPERAntiSpyware is already installed but will not run, then follow the instructions for using RUNSAS.EXE to launch the program.

================================================================================

Please download Malwarebytes Anti-Malware Posted Image and save it to your desktop.
  • Important!! When you save the mbam-setup file, rename it to something random (such as 123abc.exe) before beginning the download.
Malwarebytes 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 and double-click on the renamed file to install the application.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • Malwarebytes 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 and continue.
  • If you cannot update Malwarebytes or use the Internet to download any files to the infected computer, manually update the database by following the instructions in FAQ Section A: 4. Issues.
  • Under the Scanner tab, make sure the "Perform Quick Scan" option is selected.
  • Click on the Scan button.
  • When 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, then click the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked and then 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.
  • 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 the database version and your operating system.
  • Exit Malwarebytes when done.
Note: If Malwarebytes encounters a file that is difficult to remove, you will be asked to reboot your computer so it can proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot normally will prevent Malwarebytes from removing all the malware.

-- Some types of malware will target Malwarebytes and other security tools to keep them from running properly. If that's the case, go to Start > All Programs > Malwarebytes Anti-Malware folder > Tools > click on Malwarebytes Chameleon and follow the onscreen instructions. The Chameleon folder can be accessed by opening the program folder for Malwarebytes Anti-Malware (normally C:\Program Files\Malwarebytes' Anti-Malware or C:\Program Files (x86)\Malwarebytes' Anti-Malware).

================================================================================

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 quick 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

Your Microsoft Windows installation is out of date.
Whenever a security problem in its software is found, Microsoft will usually create a patch for it. After the patch is installed, attackers can't use the vulnerability to install malicious software on your PC, so keeping up with these patches will help to prevent malicious software being installed on your PC
Go here to check for & install updates to Microsoft applications.
Note: The update process uses ActiveX, so you will need to use Internet Explorer for it, and allow the ActiveX control that it wants to install.

Please reboot and repeat the update process until there are no more updates to install.
