There's some sort of malware on my computer I'm having a hard time tracking down.

When I search for something on Google, then click on a URL I am always redirected to some sort of advertisement/adware page, a differant one every time. This happens on almost every link I click on for every search I do, even for sites I've been to before like Wikipedia. Happens on both Internet Explorer 8 and Firefox. I've done a full system scan with Norton 360 with no results. I then disabled Norton and opened Avast and scanned with that, still nothing. However, then I ran a Boot-time scan with Avast and it found 4 infected files, all classified as high risk, which I deleted, here I will list the threats as Avast sees them and the directory Avast tells me they were at:

*E:\ is my boot drive*

Threat: Java:Djewers-N [trj]
E:%documents%\application data\sun\java\deployment\cache\6.0\42\32c0eb6a-7c00ee12|googles.class

Threat: Win32: Adan-055 [adw]
G:\Windows\downloaded program files\gsda.dll

Threat: Java:Openstream-H [trj]
G:\%documents%\application data\sun\java\deployment\cache\javapi\v1.0\jar\loaderadv669.jar-6aca14a-63c265d9.zip|>Matrix.class

Threat: Java:Openstream-H[trj]
G:\%documents%\application data\sun\java\deployment\cache\6.0\23\754cc257-4ff050a3|>Matrix.class

where %documents% is a variable for my documents folder.

Anyway, after I deleted these things nothing really happened and I still can't do Google searches without bein redirected to ads.

Currently running Norton scan, followed by Avast scan in safe mode.

Any ideas? Any way I can provide more info?

Additional info:
I recently installed Game maker 8, I'm starting to think I got infected form that.
I can type in any web address and it will work fine, its only when I do searches it doesnt work
If i click (cached) next to a google search result, I will Not get redirected to an ad.
Occasionally clicking on a search result will actually get me where I want to go. Then if I click back, and click on the result again, I'll get an ad.
Compuer has been running a bit slower than normal since I noticed this.
I don't see any suspicious processes on Task manager.

What operating system is this and what version of JAVA is running?
Go into Control Panel>Add Remove Programs. Be sure the 'Show Updates' box is checked. Go down the list and tell me what Java applications are installed and their version. (Highlight the program to see this).

Do you have 2 Antivirus applications running?


Next run MBAM (MalwareBytes):

Please download Malwarebytes Anti-Malware (v1.46) and save it to your desktop.alternate download link 1
alternate download link 2
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. Temporarily disable such programs or permit them to allow the changes.
  • 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 definition 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. Be sure to post the complete log to include the top portion which shows MBAM's database version and your operating system.
  • Exit MBAM when done.
Note: If MBAM encounters a file that is difficult to remove, you will be asked to reboot your computer so MBAM can proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.

I ran MBAM, and I think that solved the problem. It removed a few files and I don't see any signs of malware anymore. Thank you for your help.

Well if you think so OK.

Now you should Create a New Restore Point to prevent possible reinfection from an old one. Some of the malware you picked up could have been backed up, renamed and saved in System Restore. Since this is a protected directory your tools cannot access to delete these files, they sometimes can reinfect your system if you accidentally use an old restore point. Setting a new restore point AFTER cleaning your system will help prevent this and enable your computer to "roll-back" to a clean working state.

The easiest and safest way to do this is:
  • Go to Start > Programs > Accessories > System Tools and click "System Restore".
  • Choose the radio button marked "Create a Restore Point" on the first screen then click "Next". Give the R.P. a name, then click "Create". The new point will be stamped with the current date and time. Keep a log of this so you can find it easily should you need to use System Restore.
  • Then use Disk Cleanup to remove all but the most recently created Restore Point.
  • Go to Start > Run and type: Cleanmgr
  • Click "Ok". Disk Cleanup will scan your files for several minutes, then open.
  • Click the "More Options" tab, then click the "Clean up" button under System Restore.
  • Click Ok. You will be prompted with "Are you sure you want to delete all but the most recent restore point?"
  • Click Yes, then click Ok.
  • Click Yes again when prompted with "Are you sure you want to perform these actions?"
  • Disk Cleanup will remove the files and close automatically.
Vista and Windows 7 users can refer to these links: Create a New Restore Point in Vista or Windows 7 and Disk Cleanup in Vista.
