i apologize if the post isn't in the right section as i have very limited experience using forums thank you in advance

hello i have a dell inspiron 531s windows vista and whenever i try to browse through folders the taskbar and desktop short cuts disappear.
i am able to relaunch explorer.exe using the taskmanager but explorer ends up crashing quickly again sometimes it restarts itself.

and i know this is a separate problem but i think it's related as it started pretty much at the same time as the explorer thing. Every time google search this website and click the link i am redirected to other websites with the common theme of offers and services and a page of google saying that they cannot find blank (as in it literally says "blank")

i also found out that my system restore points have been deleted by something

Welcome to BC


The process of cleaning your computer may require you to temporarily disable some security programs. If you are using SpyBot Search and Destroy, please refer to Note 2 at the bottom of this page.

Please download Malwarebytes Anti-Malware and save it to your desktop.
alternate download link 1
alternate download link 2
  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
  • 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 updates, manually download them from here and just double-click on mbam-rules.exe to install.
On the Scanner tab:
  • Make sure the "Perform Quick 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 and exit MBAM.
Note:
-- If MBAM encounters a file that is difficult to remove, you may be asked to reboot your computer so it can proceed with the disinfection process. Regardless if prompted to restart the computer or not, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.

Note 2:
-- MBAM may make changes to your registry as part of its disinfection routine. If you're using other security programs that detect registry changes (like Spybot's Teatimer), they may interfere with the fix or alert you after scanning with MBAM. Please disable such programs until disinfection is complete or permit them to allow the changes. To disable these programs, please view this topic: How To Temporarily Disable Your Anti-virus, Firewall And Anti-malware Programs

hi i have been trying the full scan but MBAM keeps freezing a few hours into the scan so i have tried making it do a full scan with drive c selected and drive d deselected and this is what i got after 3 hours. Now i'm attempting to scan drive D with drive C deselected... i will follow the next steps you have provided me with after i get the next log and post it. I am not entirely sure but i think it froze at least twice on this directory (D:\windows\system32\config\security\.log1) as for the other times mbam froze i am very sure that is stopped working while scanning drive D
i also get an error message upon startup saying that the module C:\users\owner\appdata\local\temp\pmnolkkd.dll failed to load because it doesn't exist...
thank you again for the help you are giving me

pmnolkkd.dll doesn't go to anything. It might be a leftover from malware already removed. We'll deal with that after the other scans are complete

Post the SAS scan when complete

Is D: drive a removable drive? If it's your CD/DVD drive, do you have a disk in the drive?

hi
again i wasnt able to do a xomplete scan but this is the log from the C: drive and yes i do believe that the D: drive is the disc drive and i scanned it without a cd present
im also freaking out as my C: drive showed 199gb of free space 2 days ago and now its showing 79gb of free space
out of 300gb... ihave installed drawing tablet drives/software and age of empires 3 and i know those 2 do not add up to 100gb ...
but the scanning software seems to freeze up when it scans the d: drive so i am not sure how to do the scan

im sorry i just realized that the restarted scan was a quickscan not a full one ill will post the full one as soon as i can but i doubt i will get it to scan the D: drive succesfully

Put mbam on hold and try Dr. Web Cure IT
--------------------------

Please download Dr.Web CureIt, 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)
