Since a few weeks, I've had URL redirections when searching online (on google.com, bing.com, yahoo.com but not metacrawler.com or some other less known search engines) & random AD pages opening on new tabs while I'm just reading content on a page and not interacting actively with anything (they just randomly open once every hour or so).

I'm pretty sure I have a malware infectin but have no way of removing it. A friend recommended to run Malwarebytes' software and clean my computer.
I've done so and it seemed clean for a day or two and then it restarted doing the URL redirectino again.

In the last 2 days, there was a virus database update to my anti-virus, AVAST!, and since then whenever I perform a new search, it blocks a URL (recognized in Avast! as "MAL-URL") that it probably browsed by the malware installed in my browser/on my computer.

That is all fine and nice, but the random AD pages still happend and every time I search I am reminded by Avast! that it found some malware URL being browsed secretly.
I'd really feel a lot safer if this could be removed and my browsing experience could return to normal.

As a side note, all of this starting hapenning after attending a LAN with friends (as it always does... to me anyways).

I have no idea on how to go about this but I am ready to follow any steps as required of me.

Thank you.

Softtware related to the problem:
Windows XP Pro x64 SP2
Firefox 3.6.16

*EDIT: I added a watch with immediate notification, just in case :)

Hello and welcome ...Let's start here and see how we are sfter these.

Please download the TDSS Rootkit Removing Tool (TDSSKiller.exe) and save it to your Desktop. <-Important!!!
Be sure to download TDSSKiller.exe (v2.4.0.0) from Kaspersky's website and not TDSSKiller.zip which appears to be an older version 2.3.2.2 of the tool.
  • Double-click on TDSSKiller.exe to run the tool for known TDSS variants.
    Vista/Windows 7 users right-click and select Run As Administrator.
  • If TDSSKiller does not run, try renaming it.
  • To do this, right-click on TDSSKiller.exe, select Rename and give it a random name with the .com file extension (i.e. 123abc.com). If you do not see the file extension, please refer to How to change the file extension.
  • Click the Start Scan button.
  • Do not use the computer during the scan
  • If the scan completes with nothing found, click Close to exit.
  • If malicious objects are found, they will show in the Scan results - Select action for found objects and offer three options.
  • Ensure Cure (default) is selected, then click Continue > Reboot now to finish the cleaning process.
  • A log file named TDSSKiller_version_date_time_log.txt (i.e. TDSSKiller.2.4.0.0_27.07.2010_09.o7.26_log.txt) will be created and saved to the root directory (usually Local Disk C:).
  • Copy and paste the contents of that file in your next reply.



Rerun MBAM (MalwareBytes) like this:

Open MBAM in normal mode and click Update tab, select Check for Updates,when done
click Scanner tab,select Quick scan and scan (normal mode).
After scan click Remove Selected, Post new scan log and Reboot into normal mode.

Please ask any needed questions,post logs and Let us know how the PC is running now.

Hi,

Thanks for the welcoming and the help.

Only the driver for daemon tools was found, nothing else.

Do you want me to remove/disable it and try another scan afterwards or does it work even if it is loaded ?

Aside from that, I still get notices from Avast! that it is blocking something (malware URL, browser infection only maybe ?) when I search on google/yahoo/bing,etc.
I also still get the random ad (in new tabs). I just got one as I was typing this leading to "http://cydon.com/[...]".

What's next ?

*EDIT*: Sorry for the slow response, I was at school... my schedule is crap this winter semester, all 8h45 am and then big break till 20h00 !!!

Yes, disable it and spybot if running as they can interfere.
Did you rerun MBAM?


I'd like us to scan your machine with ESET OnlineScan
  • Hold down Control and click on the following link to open ESET OnlineScan in a new window.

    • Double click on the Posted Image icon on your desktop.
  • Check Posted Image
  • Click the Posted Image button.
  • Accept any security warnings from your browser.
  • Under scan settings, check Posted Image and check Remove found threats
  • Click Advanced settings and select the following:
    • Scan potentially unwanted applications
    • Scan for potentially unsafe applications
    • Enable Anti-Stealth technology
  • ESET will then download updates for itself, install itself, and begin scanning your computer. Please be patient as this can take some time.
  • When the scan completes, push Posted Image
  • Push Posted Image, and save the file to your desktop using a unique name, such as ESETScan. Include the contents of this report in your next reply.

Hey.
Yes, I rerun MBAM and still found nothing.

ESET is updating as I type this and should start scanning soon.

Thanks again!

I will post once it's done.
