Thank you for the assistance.

As no logs have been posted, I am shifting this topic from the specialized HiJack This forum to the Am I Infected forum.

PLEASE DO NOT NOW POST LOGS unless a log is specifically requested.

Please describe your issue in full and as specifically as possible. We have no idea what topic you are referring to. Also, please be aware that the process that fixed one person's malware issue may not be the same that fixes another.

Welcome, let's see what we can get from an MBAM log.

Next run MBAM:
Please download Malwarebytes Anti-Malware (v1.36) and save it to your desktop.
alternate download link 1
alternate download link 2
If you have a previous version of MBAM, remove it via Add/Remove Programs and download a fresh copy.

• 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. Alternatively, you can update through MBAM's interface from a clean computer, copy the definitions (rules.ref) located in C:\Documents and Settings\All Users\Application Data\Malwarebytes\Malwarebytes' Anti-Malware from that system to a usb stick or CD and then copy it to the infected machine.

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 using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you after scanning with MBAM. Please temporarily disable such programs or permit them to allow the changes.

First, Thank you very much for the reply.

To answer the first reply post, here is a description of the problem I have been encoountering.

One of my computer has suddenly come up with repeated warning by McAfee software that each time we opens the browser (internet explorer), she sees the following message:

"McAfee has automatically blocked a buffer overflow.

About this buffer overflow

File: C:\Program Files\Internet Explorer\iexplore.exe"

It gives the option of trusting the activity, which I have not clicked on, and closing the alert, which I have done. When clicking to close the alert, the internet explorer freezes and must be ended via CTRL+ALT+DEL.

I am posting this from another computer - my wife's computer is currently on but offline. I ran the McAfee scan and nothing came up as infected or quarantined.

Second,

Here is the results of running the MBAM

Follow on questions I have is do you have any idea what the malware and stuff was that got on my computer? Any idea where it could be from? Why didn't my Mcafee catch this?

While this removed the problem, I really don't want it back!

Thank you
Robert

Hello ,It's hard to say exactly where it came from. I suspect these came from a game download,probably packed in the installer. Sometimes you need to read everything that you are agreeing to with game d'loads,especially if they are free. in the link below,I think the second is How did I get infected. That should shed a bit more light.

Please take a moment to read quietman7's excellent prevention tips in post 17 here
Click>>Tips to protect yourself against malware and reduce the potential for re-infection:


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.
