Hello / mbam.exe file infected

Hello everyone,

I found information on this forum on the Internet and I am hoping you can help me with a problem I am having with my laptop. Everytime I open Internet Explorer I get a screen which says 'visiting this site may harm your computer!' I am unable to go on to any other websites. I also get an Antivirus Software Alert telling me to activate antivirus software.

I have tried to run Malwarebytes Anti-Malware scan but it tells me: 'Application cannot be executed. The file mbab.exe is infected.'

In the meantime, after a few minutes Internet Explorer starts up of its own accord and goes on to various dodgy websites.

Any assistance will be greatly appreciated. Many thanks in advance,

BS

We need to do some diagnostics to get started.

1. Please download and run RKill.

Download mirror 1 - Download mirror 2 - Download mirror 3

• Save it to your Desktop.
  
• Double click the RKill desktop icon.
  
• It will quickly run and launch a log. If it does not launch a log, try another download link until it does.
  
• Please post its log in your next reply.
  
• After it has run successfully, delete RKill.

Note: This tool only kills the active infection, the actual infection will not be gone. Once you reboot the infection will be active again! Please do not reboot until instructed further to do so.

2. Download MBRCheck to your desktop.

• Double click MBRCheck.exe to run (Vista and Windows 7 users, right click and select Run as Administrator).
  
• It will show a black screen with some data on it.
  
• A report called MBRcheckxxxx.txt will be on your desktop
  
• Open this report and post its content in your next reply.

3. Please download Cheetah-Anti-Rogue by me, and save to your Desktop.

• Double-click on Cheetah-Anti-Rogue.zip, and extract the file to your Desktop.
  
• Double-click on Cheetah-Anti-Rogue.cmd to start.
  
• It will finish quickly and launch a log.
  
• Post the contents of it in your next reply.

4. In your next reply, please post the following logs for my review:

• MBRCheck log (2)
• Cheetah log (3)

Thanks!
