Hello, thanks for reading my post. Heres my situation:

Windows xp MCE sp2

About 6 hours ago, I was surfing the net with firefox, when I was redirected to another page and IE opened. As soon as that happened, I killed both firefox and IE with task manager, but it was too late I think.

First and foremost I had a bubble pop up from the start bar, which looked like a legit windows warning, - it was about antivirus software, saying I needed to upgrade and to click it. However, I noticed the word prevent was misspelled in the text, so I checked out my processes. I noticed a few processes I didn't recognize, one in particular "a.exe". So, I disconnected my hardline to the internet, then I manually tried to kill these processes but they kept rebooting themselves. I ran HJT, and it was immediately terminated. I watched the process menu and noticed a process or two popped up and went away as soon as HJT was killed. The same thing happened for SmitFraudFix, and I was unable to run either program after they were killed the first time. After getting back online, I found a program from microsoft that scanned for click fraud virus type problems, but it was killed too. Well, then I located some of the corresponding registry keys for these processes and deleted them, but it made little difference other than fixing the bubble that was popping up.
And about firefox - it was slow, and I noticed that searching through google showed "Transferring data from wewewesearch.com" for a split second in the status bar. After reinstalling firefox, it was no different.
I spent the next 3 hours researching my symptoms (I had read about a case similar to mine, and dl'ed ComboFix during that time), and then things got worse.


randomly, I fired up firefox and:
Instead of loading my homepage, firefox either showed my computer or had a mock-up website of it, and it had several pop-ups - I managed to scribble one thing down from it "HTTP://spyware-remover-free.org"

Something then tried to access something from microsoft word, which caused microsoft's installer to launch and prompt me because I don't have it installed. This was not caused by me.

The last thing that happened - my default fontsize changed (my clock and desktop fonts were like twice the size, google too), so when I saw that, I killed firefox, IE (which had opened again), msi.exe, everything else I could, and even explorer.exe

That all happened within about twenty seconds, and at that point I ran ComboFix and figured if ComboFix didn't work I'd reformat.


another three hours of researching later, I happened across these forums and decided to ask for advice. Things are better so far, - they seem normal - but I thought it would be wise to ask you guys. I've got my log from ComboFix if you guys want to see it.

I really appreciate it,
Austin

Please note the message text in blue at the top of this forum.

You should not be using Combofix unless instructed to do so by a Malware Removal Expert who can interpret the logs. It is a powerful tool intended by its creator to be "used under the guidance and supervision of an expert", NOT for general public or personal use. Combofix was never meant to be used as a general purpose malware scanner like SuperAntispyware or Malwarebytes' Anti-Malware. Using this tool incorrectly could lead to disastrous problems with your operating system such as preventing it from ever starting again. Please read Combofix's Disclaimer. That's the decision by the creator and we will abide by that decision.

Further, ComboFix logs are not permitted outside the HijackThis Logs and Malware Removal forum and then only when requested by a HJT Team member.

Please download Malwarebytes Anti-Malware (v1.41) and save it to your desktop.
alternate download link 1
alternate download link 2

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.
  • 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 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 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. 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.

Please download TFC by Old Timer and save it to your desktop.

  • Click the Start button to begin the cleaning process and let it run uninterrupted to completion.
  • Important! If TFC prompts you to reboot, please do so immediately. If not prompted, manually reboot the machine anyway to ensure a complete clean.
Please download and scan with Dr.Web CureIt - alternate download link.
Follow these instructions for performing a scan in "safe mode".
If you cannot boot into safe mode or complete a scan, then try doing it in normal mode. Be aware, this scan could take a long time to complete.
-- Post the log in your next reply. If you can't find the log, try to write down what was detected/removed before exiting Dr.WebCureIt so you can provide that information.
