Last night around 1 or 2 in the morning, I was looking at websites like alluc.org. I searched for "onclickvideo" in google. I found the website that I was looking for and went to it. It was onclickvideos.com. Somewhere between that homepage and one page that I clicked on there, my browser started acting really weird. I was using firefox. Firefox started to crash everytime I re-opened it. Then I got a fake security center result saying that there is a Trojan detected. It gives me this button to click to "fix" the problem. When I click it, it takes me to defender-review.com and that webpage tells me to download the software. This is the only webpage that firefox will open without crashing. I have NOT downloaded that software. While that page was up, I opened a new tab and searched google to see if it was legit, which it was not. Firefox still wasn't acting right, so I did what the people in the forums I found said, which was to go to the AppData folder and go through there seeing what was created around the same time that it first started acting up. I went into safe mode and did this. When I restarted, firefox would not open at all. It tells me that there is already a window of firefox running but that it is not responding and to either close that window or restart.

I went to Task Manager, and it doesn't show anything firefox running.
This is what Task Manager showed.

I tried to get HijackThis, but it said "Your current internet security settings do not allow this file to be downloaded." I changed all of my internet security settings to make it download, but it keeps giving me the same message, even when I turned my entire internet security off.
I have no idea what to do to try and fix this. Firefox won't even open, so I am using Internet Explorer, which I do not trust at all.

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. 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.
The power of accurate observation is commonly called cynicism by those who haven't got it.
