I have McAfee installed on my system. It came with my Dell laptop that I recently bought.
Windows 7 was updated today. After the update i received the message that my PC is infected with PWS:Win32/Zbot.gen!
How do I determine if this is indeed the case?

Thnx

Hello lets take a second look.

Next run MBAM (MalwareBytes):

Please download Malwarebytes Anti-Malware and save it to your desktop.
Download Link 1
Download Link 2MBAM 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.
    For instructions with screenshots, please refer to the How to use Malwarebytes' Anti-Malware Guide.
  • 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'd like us to scan your machine with ESET OnlineScan

  • Under scan settings, check Posted Image and check Remove found threats

    • 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.
  • Push the Posted Image button.

Hi,

Thanks again!

Installed ESET.
There was a message that Windows Defender and McAfee might interfere with ESET, but didn't know how to stop McAfee.
Anyway, ESET didn't find any threats.

Meanwhile I learned that this trojan can be quite harmful. Is there any way of knowing if any harm was done?

Thnx
Ray

Hi Ray, Threat characteristics of ZBot - a banking trojan that disables firewall, steals sensitive financial data (credit card numbers, online banking login details), makes screen snapshots, downloads additional components, and provides a hacker with the remote access to the compromised system. ThreatExpert

This is a serious infection.. You have assume all paaswords were harvested,
If you do any banking or other financial transactions on the PC or if it should contain any other sensitive information, please get to a known clean computer and change all passwords where applicable, and it would be wise to contact those same financial institutions to apprise them of your situation.


How Do I Handle Possible Identify Theft, Internet Fraud and CC Fraud?
When Should I Format, How Should I Reinstall

It was good that ESET came clean as it would be trouble if others were found.

If you do a lot of financials on here you should consider a reinstall to guarantee the security of your personal data.

it's really frustrating that the anti-virus SW that came with the PC was not able to catch this trojan while other SW did...

many thanks for your help and your advice!

To check the Proxy...
Please click Start > Run, type inetcpl.cpl in the runbox and press enter.

Click the Connections tab and click the LAN settings option.

Verify if "Use a proxy..." is checked, if so, UNcheck it and click OK/OK to exit.

Now check if the internet is working again.
