Hi folks. Just got a major problem with my new computer and would be very grateful for help.

First off, my computer is a Dell Inspiron 530 running Windows Vista Home Premium Service Pack 1 (build 6001). I am running McAfee Security Center with VirusScan and Personal Firewall. Please let me know what other info you need I will be happy to provide it.

Over the past few days I somehow got infected with a browser hijacker, when I Google something my browser does not follow the link I click on but goes to other URLs unrelated to what I searched for.

I did several scans using McAfee and it says I am infected with NTOSKRNL HOOK. It also says it has fixed the problem after each scan but the infection keeps coming back. I have tried to use Housecall and such but have a hard time getting to those sites since my browser won't go to them. I ran Windows Defender but it did not detect any problems at all.

I did finally get to Housecall and am running it now but it says it has been runnning a scan for about 7 hours now, not sure how long a Housecall scan generally takes but it's taking a long time it seems.

There are a number of other problems as well, also beginning within the last 48 hours or so. My computer has lots of trouble booting up, sometimes making numerous attempts to boot up before either being successful, or going to the black screen which provides the option to do a regular boot or to boot in safe mode or safe mode with networking, etc. Often if I try several times to click on the regular boot up option it will eventually boot up properly. When not booting up properly it seems to reach a certain point in the boot up process then it stops and tries to start over again, sometime doing this three or four times in a row before even getting to the black screen where you choose between regular or safe mode boot up.

I was able to download and run hijackthis, I have a report from the run which I can post when needed.

I am new to all this so please let me know what else you need to help, I will be happy to do whatever it takes to try to fix this computer. Thanks very very much for your assitance!
Bill

Hello and welcome please run these next. Try running these.

Next run ATF:
Please download ATF Cleaner by Atribune & save it to your desktop.
  • 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 browser click Firefox 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.
  • If you use Opera browser click Opera 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.
Note: On Vista, "Windows Temp" is disabled. To empty "Windows Temp" ATF-Cleaner must be "Run as an Administrator".


Next run MBAM:
Please download Malwarebytes Anti-Malware (v1.32) and save it to your desktop.
alternate download link 1
alternate download link 2
If you have a previous version of MBAM, remove it via Add/Remove Programs and download a fresh copy.
  • 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. Alternatively, you can update through MBAM's interface from a clean computer, copy the definitions (rules.ref) located in C:\Documents and Settings\All Users\Application Data\Malwarebytes\Malwarebytes' Anti-Malware from that system to a usb stick or CD and then copy it to the infected machine.
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. 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 after scanning with MBAM. Please temporarily disable such programs or permit them to allow the changes.

Something is still not quite right.

Since I now don't even have internet access any longer I am posting this from work....

OK so I ran the Anti-Malware program several times and it finally came up as finding zero infection. Good news. I also ran my McAfee virus scan once and it came up clean too....

Unfortunately after doing that I tried to reboot and now my computer can only boot up in normal mode about 10% of the time, every other time it boots up in safe mode.

Also, once booted up, whether in normal or safe mode, most of my programs no longer work. For example, once booted up I have no internet access as my USB network adapter no longer works. In fact, my system tray is gone along with all the programs in it such as my virus scanner and my network stuff so on. Also, when I go to start programs such as Photoshop they don't start, I just get the spinning icon that indicates a program is trying to start but then nothing happens. I don't know why I had the opportunity to run my McAfee virus scan once, but now it won't run at all.

And, just to keep things interesting, on the rare times I do get booted up in normal mode after a matter of a minute or two Windows just crashes and tried to reboot, generally to safe mode.

Just FYI I connect to the internet using a little Netgear USB adapter that allows me to connect to the wireless network my upstairs neighbors have set up.

AND, when I try to reboot I get one of the mult-colored sort of shutdown screens but Windows never actually shuts down, it just remains locked on that screen without actually shutting down. In fact, it was stuck on that screen for about 3 hours last night before I had to manually shut my computer off by pressing the power button until it finally shut down.

So I think the virus or malware that I had may have been removed, unfortunately there is not much left of my brand new computer that works.

Thanks again for any assistance anyone can provide. This is really a huge disappointment.

In some instances an infection may have caused so much damage to your system that it cannot be completely cleaned or repaired. Wiping your drive, reformatting, and performing a clean install of the OS or doing a factory restore removes everything and is the safest action.
Reformatting a hard disk deletes all data. If you decide to reformat, you can back up all your important documents, data files and photos. The safest practice is not to backup any autorun.ini or .exe files because they may be infected. Some types of malware may disguise itself by adding and hiding its extension to the existing extension of files so be sure you take a close look at the full name. After reformatting, as a precaution, make sure you scan these files with your anti-virus prior to copying them back to your hard drive.

When Should I Format, How Should I Reinstall

I ended up doing a factory restore and it seems to be good as new. Which I guess is the point of a factory restore right? :thumbsup:

Anyway, thanks very much for the assistance, as I guess we all know how much is stinks when suddenly you are computerless!!! It's like losing a friend.

Hi, believe me I hated to have to say it. I guess i should ask if you mean you wiped(formatted ) the drive and reinstalled the OS,just so we arre talking about the same thing.
