Hi, I'm new to these boards, but I must say that based on some of the discussions in here - you guys are really excellent and extrmely helpful. I really hope to learn a great deal here.

Let me start by saying that for the first time in many, many years - I have caught a computer virus and boy, am I taken by surprise just how stubbon they are to remove. At first, I got one of those 'You're computer is infected' popups and 'you need to download our software' thing they tend to write and that also resulted in a big ugly sign saying the same thing on my wallpaper.

Before the malware infection, I have been using Avira, malware bytes and hijack this. At one point, I did a bit of research and used SDfix and after I thought I had killed that malware (it appeared it did), it came back in a different form, somewhat more stubborn than before. Suddenly, firefox, which was perfect till point - was now fair game.

Today, I noticed that my computer had suddenly downloaded the latest firefox beta 3.5, even though that's not the latest and I already had another firefox browser installed. Even so, I tried a few web pages and it quickly redirected me around the place to strange ad supported websites, scam websites, fake antivirus websites etc.

I then used hijack this and found a few crazy trusted zone sites I had never heard from and promtly deleted them. But still, im having probs - only with firefox. But im worried, the whole computer is infected. I've run countless scans, etc and there are plenty of trojans being picked up by Avira, although I can't really tell what aren't false positives. I'm experienced in technology, but not malware solving. This I hope to learn from the forum regulars.

I am very happy to post all my logs, etc and will be very keen to learn as we go along.

I look forward to working through the solution with somebody more informed in these areas. Many thanks im advance,

Sir Harry.

Hi Sir Harry.

Welcome to BC...

Let's get a look at your Malwarebytes log and try a things to see what files are infecting you. I want to rerun Malwarebytes, but run a few things before it.

:trumpet: Please download TFC by Old Timer and save it to your desktop.
alternate download link
  • Save any unsaved work. TFC will close ALL open programs including your browser!
  • Double-click on TFC.exe to run it. If you are using Vista, right-click on the file and choose Run As Administrator.
  • 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.
:flowers: Please download RKill by Grinler

Link #1
Link #2
Link #3
Link #4

  • Before we begin, you should disable your anti-malware softwares you have installed so they do not interfere RKill running as some anti-malware softwares detect RKill as malicious. Please refer to this page if you are not sure how.
  • Download Link #1.
  • Save it to your Desktop.
  • Double click the RKill desktop icon.
    If you are using Vista please right click and run as Admin!
  • A black screen will briefly flash indicating a successful run.
  • If this does not occur please delete that application and download Link #2.
  • Continue process until the tool runs.
  • If the tool does not run from any of the links tell me about it.
:thumbsup: 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.
-- 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
