Hi guys - here is a description of my problem.

Around 3 or 4 weeks ago I became infected with acouple of trojans (according to Norton) so I deleted them (Virtumonde or something like that?)

Then ever since then my windows security alerts balloon keeps flashing red. When I click on it I can't re-enable the feature and my laptop has been running really slow.

I have hijak this and spybot enabled - plus ad-aware (which always says that new data Rundll32.exe "C:WINDOWS\system32\silxpchs.dll",s is always trying to add itself. The value is BM5796bdc3)

Hopefully this means something to someone and you can help?

Thank you so much in advance.

You can get rid of the virtumonde infection with relative ease. Download the virtumonde removal tool from F-Secure here:
http://www.f-secure.com/download-purchase/tools.shtml

Just double click the downloaded file and press 'y' on your keyboard. It doesn't scan, it just removes, so it should be relatively quick.

That should remove the infection, but if it doesn't, try the Windows Malicous Software Removal Tool here:
http://www.microsoft.com/downloads/details...;displaylang=en

I then recommend you get an online virus scan from Kaspersky here:
http://www.kaspersky.com/virusscanner
(you must go to this website in Internet Explorer, otherwise it won't work)

And finally you should download MalwareBytes Antimalware here:
http://www.malwarebytes.org/mbam.php

Before you scan, make sure you update by click the 'Update' tab accross the top. Once stuff has been removed, if it asks you to restart you should do it straight away to prevent re-infection

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.
Note: 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. MBAM may make changes to your registry as part of its disinfection routine. If you're using other security programs that detect registry changes, they may alert you after scanning with MBAM. Please permit the program to allow the changes.

Your MBAM log indicates some files will be deleted on reboot. If MBAM encounters a file that is difficult to remove, you need to restart the computer so the malware can be fully removed. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware. If you have not rebooted, make sure you do this. When done, rescan again with MBAM and check all items found for removal. Then click the Logs tab and copy/paste the contents of the new report in your next reply. If you did reboot, then rescan again anyway and post a new log.

If there are no more problems or signs of infection, 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 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.
  • 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.

hi again.

I've been away since we last spoke.

After doing everything you said my laptop is running smoothly but the internet is very intermittent.

I have another laptop I'm using now via wireless too and its working fine - but the problem laptop internet is really sluggish and keeps resetting.

I have no has a chance to do the system resore point yet but thought its best to report this problem first.

Thank you for all your help so far.

If you are having trouble logging into a website or Internet Explorer is behaving oddly, see:
"It's not always malware: How to fix the top 10 Internet Explorer issues".

If you're using Internet Explorer 7, see:
"Why is my Internet connection so slow?".
"Windows Vista - My Internet connection is slow".
"Tuning IE7 for Better Performance".
"How to optimize or reset Internet Explorer 7".
"How to Reinstall or Repair Internet Explorer 7".

The Phishing Filter could be causing your computer to respond very slowly as it evaluates Web page contents. See "The Phishing Filter may slow down the PC" and "Phishing Filter FAQs".

If you have a lot of toolbars, BHOs and add-ons attached to Internet Explorer, you could try improving performance by disabling those which are unnecessary. Sometimes add-ons cause Internet Explorer to quit unexpectedly or not perform properly especially if the add-on was poorly designed or was created for an earlier version of Internet Explorer. Incompatible browser extensions and add-ons can also cause compatibility issues such as application hangs in IE. See Control Internet Explorer Add-ons with Add-on Manager and Troubleshooting and Internet Explorerís (No Add-ons) Mode.
