Unwanted IE

[Corax]

Hello,

I have a very annoying problem, while working with Mozilla Firefox, suddenly, once for a while, for no reason, Internet Explorer opens and starts connecting to some website (broadcaster.com). My firewall says then, that IE tries to connect to the internet and a system32 file called svchost.exe is its parental application. Furthermore there is also some kind of a popup with some ads and a search bar after sites such as google.

Scanning for viruses, spyware, cookies and deleting the stuff I found didn't do the trick

Thank you for help beforehand.

Hi,

Thanks for the brief Here is the log from HijackThis (renamed the executable to Analyze as posted):

Your HJT log is clean as a whistle.

However, something doesn`t sound quite right.

Before diving in to the instructions in the sticky thread, please do the following.

Download the Autoruns programme from HERE. When the programme runs, click options and make sure the "Hide Microsoft Entries" is ticked. Click the file menu and select refresh. Click the save icon and save the Autoruns log to wherever you want.

Attach the Autoruns log here.

Here is the log from Autoruns with hidden Microsoft entries:

 

[howard_hopkinso]

I`ve found one nasty entry in your Autoruns log. This is only the second time I`ve come across this file and it appears to be some kind of unidentified trojan/worm. The file in questions is core.sys.

1. Please download The Avenger by Swandog46 from HERE. Save it to your Desktop and extract it.

2. Download the attached avengerscript.txt and save it to your desktop

Note: the above code was created specifically for this user. If you are not this user, do NOT follow these directions as they could damage the workings of your system.

3. Now, start The Avenger program by double clicking on its icon on your desktop.

Under "Script file to execute" choose "Load script from file".
Now click on the folder icon which will open a new window titled "open Script File"
navigate to the file you have just downloaded, click on it and press open
Now click on the Green Light to begin execution of the script
Answer "Yes" twice when prompted.

4. The Avenger will automatically do the following:

It will Restart your computer. ( In cases where the code to execute contains "Drivers to Unload", The Avenger will actually restart your system twice.)
On reboot, it will briefly open a black command window on your desktop, this is normal.
After the restart, it creates a log file that should open with the results of Avenger’s actions. This log file will be located at C:\avenger.txt
The Avenger will also have backed up all the files, etc., that you asked it to delete, and will have zipped them and moved the zip archives to C:\avenger\backup.zip.

5. Please attach the content of c:\avenger.txt into your reply and let me know if you`re still having problems.

Dear Howard, let me just say, that I feel lucky, that you already had anything to do with core.sys file. So far so good! After reboot, when this thingy was deleted, no IE opening while using Firefox, also no search bar after googles. I made few more reboots after some time, just to be sure. Everything seems fine now.

Thank you very much for help!

Best regards!

Oh, and just to finish the formalities, here is the log from Avenger:

 

[howard_hopkinso]

Turn off system restore.(XP/ME only) See how HERE.

Now, turn system restore back on. This will have deleted all your old restore points and any nasties that are in them. It will also have created a new, clean restore point.

If you have any further virus/spyware problems, please post in this thread.

Regards Howard
