Hello - first time post here.

I am working on my wife's computer which is running Vista Home Premium.

The machine had a nasty virus that pretended to be a antivirus program (called antivirus soft). I removed the virus or at least the main symptom of the virus (which was that it would not allow programs other than Internet Explorer to run) by running Malwarebytes and SuperAntiSpyware, both are the free editions. I scanned several times after removing infected files and both programs showed the computer as free from infection.

It is a week later and although there is no sign of the original virus, but Internet Explorer and Firefox are now redirecting me to junk websites when I click links from google searches. I have scanned the machine again using Malwarebytes, but the logs are showing the computer as clean.

Thanks in advance for any and all assistance.

Hello and :thumbsup: to BleepingComputer!

GMER
-------
Please download GMER from one of the following locations and save it to your desktop:
  • Main Mirror
    This version will download a randomly named file (Recommended)
  • Zipped Mirror
    This version will download a zip file you will need to extract first. If you use this mirror, please extract the zip file to your desktop.
  • Disconnect from the Internet and close all running programs.
  • Temporarily disable any real-time active protection so your security programs will not conflict with gmer's driver.
  • Double-click on the randomly named GMER file (i.e. n7gmo46c.exe) and allow the gmer.sys driver to load if asked.
  • Note: If you downloaded the zipped version, extract the file to its own folder such as C:\gmer and then double-click on gmer.exe.

    Posted Image
  • GMER will open to the Rootkit/Malware tab and perform an automatic quick scan when first run. (do not use the computer while the scan is in progress)
  • If you receive a WARNING!!! about rootkit activity and are asked to fully scan your system...click NO.
  • Make sure only the Sections option is checked, leave everything else unchecked!
  • Now click the Scan button. If you see a rootkit warning window, click OK.
  • When the scan is finished, click the Save... button to save the scan results to your Desktop. Save the file as gmer.log.
  • Click the Copy button and paste the results into your next reply.
  • Exit GMER and re-enable all active protection when done.
-- If you encounter any problems, try running GMER in Safe Mode.

regards, Elise

Hi Elise025

Thanks for the response.

I downloaded GMER and while scanning received a blue screen letting me know that my computer had encountered a problem and was being shut down to prevent damage.

It then restarted within 20 seconds went back to the same blue screen and restart mode.

I then received a black DOS screen that indicated that I had a problem and a recommendation that I run Windows Startup Repair. Which I am currently doing (it is taking quite a while).

If this was a bad move - please let me know, if not I will report back once this finishes and I am able to complete the GMER scan.

Thanks!

Nope, startup repair wasn't a bad move at all :thumbsup:

Could you please check out if you are still having the redirects (it is possible startup repair fixed this).

regards, Elise

No such luck. :thumbsup:

Startup Repair did complete its scan and ran its "attempting to repair" mode, but when it was done said that it wasn't able to fix the problem.

Well that TDSkiller program found a TDS bug and deleted it.

I ran a full scan with malwarebytes as instructed afterwards and it was clean - which isn't surprising considering it couldn't see this virus all along.

I have no idea what tipped you off to this solution, BUT HUGE THANKS. :thumbsup:


My computer seems to be operating normally, but if there is anything you would have me do to ensure that I am home free, please let me know.


:flowers: :trumpet:

I am glad to hear that :flowers:

This is a nasty rootkit that is quite common unfortunately and is characterized by persistent redirects. Usually normal security applications do not detect it, or, if they do, they cannot fix it.

Please read these advices, in order to prevent reinfecting your PC:
  • Install and update the following programs regularly:
    • an outbound firewall
      A comprehensive tutorial and a list of possible firewalls can be found here.
    • an AntiVirus Software
      It is imperative that you update your AntiVirus Software on regular basis.If you do not update your AntiVirus Software then it will not be able to catch the latest threats.
    • an Anti-Spyware program
      Malware Byte's Anti Malware is an excellent Anti-Spyware scanner. It's scan times are usually under ten minutes, and has excellent detection and removal rates.
      SUPERAntiSpyware is another good scanner with high detection and removal rates.
      Both programs are free for non commercial home use but provide a resident and do not nag if you purchase the paid versions.
    • Spyware Blaster
      A tutorial for Spywareblaster can be found here. If you wish, the commercial version provides automatic updating.
    • MVPs hosts file
      A tutorial for MVPs hosts file can be found here. If you would like automatic updates you might want to take a look at HostMan host file manager. For more information on thehosts file, and what it can do for you,please consult the Tutorial on the Hosts file
  • Keep Windows (and your other Microsoft software) up to date!
    I cannot stress how important this is enough. Often holes are found in Internet Explorer or Windows itself that require patching. Sometimes these holes will allow an attacker unrestricted access to your computer.
    Therefore, please, visit the Microsoft Update Website and follow the on screen instructions to setup Microsoft Update. Also follow the instructions to update your system. Please REBOOT and repeat this process until there are no more updates to install!!
  • Keep your other software up to date as well
    Software does not need to be made by Microsoft to be insecure. You can use the Secunia Online Software occasionally to help you check for out of date software on yourmachine.
  • Stay up to date!
    The MOST IMPORTANT part of any security setup is keeping the software up to date. Malware writers release new variants every single day. If your software updates don't keep up, then the malware will always be one step ahead. Not a good thing.
Some more links you might find of interest:

regards, Elise
